ESOPHAGECTOMY : SURGICAL
APPROACHES AND CURRENT
EVIDENCE
DR AMIT DANGI
• Localized disease : 22 percent of all cases [1].
• Regional disease : 30 percent of patients.
• Goal of surgical management is curative.
• Surgical resection is the traditional mainstay of multidisciplinary
therapy for patients with localized disease [2-5].
• The clinical spectrum of esophageal cancer has changed over the last
few decades, with an increase in incidence of adenocarcinoma and a
decrease of squamous cell carcinoma [6-11].
• Surgical management is independent of histology.
ANATOMY
• 25 to 30 cm in length
• Posterior mediastinum.
• C6-T11
Anatomy of esophageal cancer primary
site, including typical endoscopic
measurements of each region
measured from the incisors.
Exact measurements depend on body
size and height. For tumors of the EGJ
and cardia, location of cancer primary
site (ie, esophagus, stomach) is defined
by cancer epicenter.
Divided into 4 anatomic areas
• Cervical
• Thoracic
• Lower thoracic/Esophagogastric
junction
• Abdominal esophagus (figure 4 and
figure 5 and figure 6).
• The esophagus is composed of
the mucosa, submucosa,
muscularis externa, and
adventitia (image 1).
• There are three critical anatomic
points of narrowing:
Cricopharyngeus ,
Broncho-aortic
constriction,
Esophagogastric junction.
• These are also the most common
sites of iatrogenic and
mechanical perforation (figure 7
and figure 8) [12].
BLOOD SUPPLY
Arterial supply:
• Inferior thyroid artery (cervical
esophagus),
• Bronchial arteries, and the aorta (thoracic
esophagus)
• Branches of the LGA and inferior phrenic
artery (abdominal esophagus).
Venous drainage:
• Inferior thyroid vein (cervical esophagus);
• Aygous vein, the hemiazygous vein, or the
bronchial veins (thoracic esophagus);
• Coronary vein (abdominal esophagus)
LYMPHATIC SUPPLY
• Rich network of submucosal lymphatic
that facilitate the longitudinal spread
of neoplastic cells along the
esophageal wall.
• Lymphatic drainage is to cervical
nodes, tracheobronchial and
mediastinal nodes, and gastric and
celiac nodes.
• An important point is that the regional
lymph nodes for all locations in the
esophagus, including the cervical
esophagus and esophagogastric
junction, extend from the
periesophageal cervical nodes to celiac
nodes.
HISTOLOGY OF ESOPHAGEAL CANCER
SQUAMOUS CELL CARCINOMA
• SCC arises from the cells that line the upper part of
esophagus.
• Smoking and alcohol
• Dietary factors : Alfatoxin, hot beverages, N nitroso
compounds, areca nut, red meat, low selenium,
zinc deficiency
• Underlying disease: Achalasia : 16 fold
Corrosive ingestion
• Prior gastrectomy or Atrophic gastritis
• HPV
• Tylosis
• Oral bisphosphonates
• Poor oral hygiene
ADENOCARCINOMA
• Adenocarcinoma arises from glandular cells
that are present at the GEJ.
• Barrett Metaplasia : 30 fold
• GERD
• Obesity and metabolic syndrome
• Smoking
• No association with alcohol
TNM STAGING (8th edition 2017)
• Recognizes biologic heterogeneity and provides separate stage groupings
for adenocarcinoma and SCC.
• Tumors involving the EGJ with the tumor epicenter no more than 2 cm into
the proximal stomach are staged as esophageal cancers.
• In contrast, EGJ tumors with their epicenters located more than 2 cm into
the proximal stomach are staged as stomach cancers, as are all cardia
cancers not involving the EGJ, even if they are within 2 cm of the EGJ.
• Thus, regardless of histology and Siewert type, esophageal tumors arising
in the cervical, thoracic esophagus or abdominal esophagus, and those
involving the EGJ that have an epicenter within 2 cm of the EGJ share the
same criteria for T stage, N stage, and M stage designation
PRETREATMENT EVALUATION
Endoscopic biopsy : 98% diagnosis with 7 biopsies (100% if brush
cytology added)
Computed tomography (CT) of the neck, chest and abdomen.
Endoscopic ultrasound (EUS) : Preferred for loco-regional staging.
Positron emission tomography (PET): Detect occult mets in 20%
Diagnostic laparoscopy and thoracoscopy : Selective use, invasive,
more accurate than CT or EUS alone, no comparison with EUS +
PET/CT
Brochoscopy and VDL.
SUV which reflects the metabolic activity of the tumor may also serve as a prognostic factor.
A high SUV predicted a worse survival.
However, some studies suggested a better response to NACRT in this group, but is uncertain.
Suspicious PET findings should be confirmed with biopsy before excluding a patient from
surgical consideration, given the high rate of false-positive findings.
Detect occult mets after CRT or induction CT in approx 8% of patients.
Role of Diagnostic laparoscopy
NCCN
Consider DL to be "optional" for patients with EGJ
tumors and no evidence of metastatic disease.
ESMO
Advocate DL for all patients with locally advanced
(T3/T4) adenocarcinomas of the EGJ infiltrating the
gastric cardia.
SAGES
Early stage esophageal cancer with no evidence of
distant or LN metastases on high- quality
preoperative imaging), who are considered for
curative resection may benefit from staging
laparoscopy (grade B).
The need for diagnostic laparoscopy for patients who appear to have potentially resectable distal esophageal and EGJ
adenocarcinomas is controversial.
IMPORTANCE OF PRE-TREATMENT STAGING
ASSESSMENT
• T1N0 : High cure rate from surgical or endoscopic therapy alone.
• Surgery: Primary curative modality for both esophageal and EGJ cancers
that have invaded through the esophageal wall or are node positive : Poor
long-term outcome with resection alone (even R0).
• T3 or N+ tumors: NACRT is generally preferred over initial surgery.
• Optimal approach to clinical T2N0 disease is debated.
• NCCN suggest NACRT for clinical T2N0 adenocarcinomas of the distal
esophagus and EGJ, and initial resection for clinical T2N0 SCC if they are <2
cm and well differentiated.
• Regardless of histology, between 50 and 80 percent of patients with
esophageal and EGJ cancers present with incurable, locally advanced
unresectable or metastatic disease.
Criteria for resection
Esophagectomy as first line of
therapy
● cT1N0M0 lesions
● cT2N0M0 lesions are candidates in
many medical centers
Esophagectomy following
NACT/NACRT
● Patients with thoracic esophageal
or EGJ tumors and full-thickness (T3)
involvement of the esophagus
with/without nodal disease.
● cT4a disease with invasion of
local structures (pericardium, pleura,
and/or diaphragm only) that can be
resected en bloc, and who are
without evidence of metastatic
disease to other organs (eg, liver,
colon).
cPR
• Surgical resection is recommended.
• cPR seen in 20-25% of patients.
• However, it is not possible to reliably identify these patients either by
EUS or repeat PET scan.
• The recommendation is to proceed with resection if the patient is fit
for surgery and has not progressed during chemoradiotherapy
Surgery after NACRT
• The impact of NACT/NACRT on perioperative morbidity and mortality
was addressed in a meta-analysis of 23 randomized trials comparing
neoadjuvant therapy versus surgery alone or NACT versus CRT [16].
• Neither NACT/NACRT increased the risk of total postoperative
mortality or morbidity.
• However, subgroup analysis suggested that patients undergoing
NACRT for SCC might be at an elevated risk for postoperative
mortality relative to those treated by surgery alone (risk ratio 1.95,
95% CI 1.06-3.6).
Relative contraindications
● Advanced age
● Comorbid illness
Indicators of unresectability —
• Metastatic disease
• Extra-regional LN spread (eg,
paraaortic or mesenteric
lymphadenopathy).
• The regional lymph nodes for
all locations in the esophagus,
including the cervical and
EGJ, extend from the
periesophageal cervical nodes
to celiac nodes.
• Celiac nodal metastases and
mediastinal/supraclavicular
nodes are scored as regional
nodal disease TNM staging
system, regardless of the
primary tumor location.
• Number rather than location
of involved LN determines
the N stage
(A-C) Lymph node maps for esophageal cancer. Regional lymph node stations for staging esophageal cancer from left (A),
right (B), and anterior (C).
PREOPERATIVE OPTIMIZATION
• PREOPERATIVE RESPIRATORY REHABILITATION —A retrospective
cohort study of 100 patients undergoing an esophagectomy found
that patients managed with preoperative respiratory rehabilitation (n
= 63) for seven days had a lower rate of postoperative pulmonary
complications (6 versus 24 percent) [18].
• NUTRITION AND IMMUNONUTRITION-
OPERATIVE PROCEDURES
Cervical esophageal cancer resection
• CRT : Primary modality
• Surgical resection : Patients who fail CRT, or who opt for a surgical resection.
• Resection usually requires removal of portions of the pharynx, the larynx, the
thyroid gland, and portions of the proximal esophagus.
• Single stage, three-phase operation requires cervical, abdominal, and thoracic
incisions.
• Permanent terminal tracheostomy.
• Bilateral radical neck dissections are generally performed [19-29].
• Restoration of GIT continuity with a gastric pull-up and anastomosis to the
pharynx.
• Free jejunal interposition graft or a deltopectoral or pectoralis major
myocutaneous flap are alternative reconstructive options.
Thoracic cancer resection
• EAC and SCC involving the middle or lower third of the esophagus (except GEJ
cancers), generally requires total esophagectomy (submucosal skip lesions) [30-
32].
• In selected superficial or early invasive esophageal cancer arising distally in the
setting of BE, a more limited resection can be performed.
• Optimal surgical approach : Unknown [33-35].
• Choice of surgical approach depends upon many factors:
● Tumor location, length, submucosal extension, and adherence to surrounding
structures
● The type or extent of lymphadenectomy desired
● The conduit to be used to restore GIT
● Postoperative bile reflux
● The preference of the surgeon
• The THE, Ivor-Lewis (TTE), and tri-incisional esophagectomy
(McKeown) procedures are the most commonly performed
esophagectomies in North America.
• Extended (three-field) lymphadenectomy is commonly performed in
Asia [36-42].
• Gastric interposition: preferred conduit
• Jejunum or the colon can also be used as the conduit [43-47].
• These conduits are resistant to the effects of gastric acid, and they
have a shape similar to the native esophagus.
Transhiatal esophagectomy
• Cervical, thoracic, and EGJ cancers.
• Upper midline laparotomy incision and a left neck incision[48,49].
• Blunt dissection of thoracic esophagus.
• Cervical anastomosis with a gastric pull-up.
• Disadvantages: Limited thoracic lymphadenectomy and blind midthoracic dissection.
• In the largest prospective database series of 2007 patients, the in-hospital mortality rate
decreased in the 1998 to 2006 cohort (n = 944 patients) compared with the 1976 to 1998 cohort
(1 versus 4 percent) [50].
• The anastomotic leak rate was also lower in the 1998 to 2006 cohort (9 versus 14 percent).
• Other postoperative complications included atelectasis and pneumonia (2 percent), and
intrathoracic hemorrhage, RLN paralysis, chylothorax, and tracheal laceration in <1 percent each.
Orringer MB, et al. Ann Surg. 2007
Ivor-Lewis transthoracic esophagectomy
• Lower third of the esophagus.
• Not the optimal approach for cancers located in the middle third because of the limited
proximal margin that can be achieved.
• Combines a laparotomy with a right thoracotomy and an intrathoracic anastomosis.
• Direct visualization of the thoracic esophagus & allows a full thoracic lymphadenectomy.
• Minimally invasive Ivor-Lewis approach to a thoracotomy.
• Disadvantages :
Limited length of proximal esophagus that can be resected to achieve a R0,
Intrathoracic anastomosis.
3 to 20 percent risk of severe bile reflux [51,56].
Higher morbidity (64%) and mortality associated with leak [57-62].
With current technique, mortality rates are substantially lower [63].
Modified Ivor-Lewis transthoracic
esophagectomy
Left thoracoabdominal incision (single incision)
Gastric pull-up and an esophagogastric anastomosis in the left chest
[77].
Most useful for tumors involving the GEJ.
Disadvantages include a high incidence of complications such as
postoperative reflux and limitation of the proximal esophageal margin
by the aortic arch.
Tri-incisional esophagectomy
• Combines the THE and TTE approaches (MIS can be perfomed)
• Transthoracic total esophagectomy with a thoracic lymphadenectomy and
cervical anastomosis [78-82].
• Allows a complete 2-field (mediastinal and upper abdominal)
lymphadenectomy under direct vision.
• Advantages of a neck anastomosis :
Easier management of a possible leak
Lower reflux
More extensive proximal resection margin
Location outside of radiation ports if administered preoperatively.
Oncological principles
1. Thoracotomy
A right posterolateral thoracotomy or a thoracoscopy is performed to assess
resectability and exclude local invasion of contiguous structures.
En bloc resection is performed
2. Laparotomy
Metastatic disease is excluded, and the stomach is mobilized with
construction of conduit.
3. Neck incision –
Left neck exposure preferred.
Left RLN recurs lower (around the aortic arch) than the right RLN, which recurs
around the subclavian artery and is therefore more likely to be injured from a right
neck approach.
Annals RCT
EGJ cancer resection
• Surgical management is standard of care
includes either an esophagectomy with partial
or extended gastrectomy, with/out
thoracotomy.
• Principles:
R0 resection,
4-cm (distal) gastric margin,
5-cm esophageal margin, and
Resection of at least 15 nodes in
basins appropriate for the primary tumor.
• Solely transabdominal approach without
thoracoabdominal incision or THE is not
acceptable for tumors that involve the distal
esophagus.
Siewert JR, et al. Chirurg 1987
• The contemporary operative approach for EGJ cancer is based upon
findings of 2 phase III trials.
● A Japanese trial (JCOG 9502)
Compared THE vs extended esophagectomy using a left
thoracoabdominal approach (LTA) for patients with Sievert
type II or III adenocarcinoma.
THE gp: Received a total gastrectomy plus a D2
lymphadenectomy (including splenectomy) and PALND.
LTA gp: Underwent thorough mediastinal nodal dissection
below the left IPV + D2 abdominal LAD.
The trial closed prematurely when a planned interim
analysis concluded that it was unlikely that LTA would be
significantly better than TH.
• 5 yr OS was lower in the LTA group (38 vs 52 %, p>0.05),
• 10 yr OS: 24 versus 37 percent (p>0.05)[89].
• More complications and mortality in LTA gp.
• Conclusion: LTA could not be recommended for type II/III
tumors.
● A phase III Dutch trial
N=220 patients with Siewert type I or II adenocarcinoma
Assigned to
a. THE
b. Extended thoracic resection (TTE) with an extended en
bloc lymphadenectomy via the right thoracic approach
[RTA]) [73,86].
• Similar In-hospital mortality.
• More pulmonary complications and postoperative
chylous leakage after RTA.
• More ICU and total hospital stays in RTA group [86].
• Similar 5 yr OS (36 versus 34 percent for RTA and THE)
• Better survival with extended thoracic resection in the
patients with a type I tumor (five-year survival 51
versus 37 percent, p = 0.33).
• Conclusions : Given the greater hazards a/w with
extended transthoracic resection, it could only be
recommended for patients with type I and not type II
tumors.

Type II
Arises from the cardia or the EGJ.
Resected by a total gastrectomy, distal
esophagectomy, and regional lymphadenectomy.
Type I
Located in the distal esophagus.
Resected by a subtotal gastrectomy, subtotal
esophagectomy, and regional lymphadenectomy.
Type III

infiltrates the EGJ and distal esophagus from
below.
Resected by a total gastrectomy, distal
esophagectomy, and regional lymphadenectomy
Open versus minimally invasive
Advantages of MIS include :
● Smaller incisions
● Less blood loss
● Fewer postop complications
● Shorter ICU and hospital stay
● Better preservation of
postoperative pulmonary function
Areas of uncertainty include:
● Optimal minimally invasive
procedure
● Adequacy of the esophageal and
gastric surgical margins
● Extent of LN dissection
● Safety of minimally invasive
esophagectomy in patients who have
undergone preoperative radiation
therapy
● Long-term oncologic outcomes
Safety of MIS Esophagectomy
• No consensus that MIE is associated with a decrease in 30-day
mortality and overall morbidity, as found in many retrospective and
prospective studies:
n=75,502 Esophagectomy
n = 1155 : MIE
• No significant benefits as defined by a decrease in 30-day mortality
and overall morbidity (4.3 versus 4.0 percent and 38.0 versus 39.2
percent, respectively).
• The re-intervention rate was significantly higher for patients
undergoing an MIE compared with an open esophagectomy (21.0
versus 17.6 percent).
A prospective TIME trial found that patients undergoing an MIE have a better
perioperative hospital course.
N=115
Patients undergoing an MIE had
• Lower rate of in hospital pulmonary infections (12 vs 34%)
• Lower perioperative (within 2 weeks) pulmonary infections (9 vs 29%).
• Similar DFS (36 versus 40 percent) and 3 yr OS (40 versus 51 percent)
12 studies
N = 672 MIE or hybrid minimally invasive esophagectomy (HMIE)
N = 612 Open esophagectomy
No significant difference in
• 30-day mortality.
• Frequency of anastomotic leak
MIS procedures were associated with
• Significantly lower blood loss
• Shorter ICU and hospital stay
• Fewer respiratory complications.
• 50 % reduction in total morbidity.
• Total morbidity was similar for HMIE
procedure and open esophagectomy.
• Lap THE was associated with
Fewer overall complications (risk ratio 0.64, 95% CI 0.48-0.86)
Fewer serious complications (risk ratio 0.49, 95% CI 0.24-0.99)
Shorter hospital stays (by three days).
However, RCTs are needed to determine the optimal approach to THE.
Total MIE approach
• Limited data for oncologic outcomes.
• In the largest series with oncologic outcomes, 70 of 77 attempts to perform a total MIE were successful.
2 yr OS and DFS were 81 and 74 %, respectively.
Recurrence was documented in 14 patients, 11 of which were distant recurrences.
• No RCTs comparing any form of MIE to an open procedure.
• However, a retrospective Australian series compared outcomes among
• 114 patients : open esophagectomy,
• 309 patients; Thoracoscopic-assisted surgery (TAS)
• 23 patients : Total MIE
While the data suggest potential for a total MIE approach, this cannot be considered a
standard approach.
Berrisford RG, et al; Br J Surg 2008; 95:602.
Smithers BM, et al.. Ann Surg 2007; 245:232.
No differences in the rate of margin positivity or
the no of LN retrieved,
No difference in the time to recurrence or
median or 3 yr OS (compared stage for stage).
Combined approach
• Thoracoscopic mobilization of the esophagus + node dissection combined with open laparotomy.
• Most popular MIE technique with the most extensive published experience.
• Relative C/I to thoracoscopic surgery include
Inadequate pulmonary function,
Extensive pleural adhesions,
Prior pneumonectomy,
Bulky tumors,
Locally infiltrative tumors, particularly those with airway involvement

Circumferential resection margin
• Unclear prognostic role till recently
• The College of American Pathologists (CAP) defines a positive CRM as the
presence of esophageal cancer at the resection margin.
• The United Kingdom Royal College of Pathologists (RCP) defines a positive
CRM as the presence of esophageal cancer within 1 mm of the resection
margin.
• CAP criteria differentiate a higher-risk group of patients with resectable
esophageal cancer than the RCP criteria.
• Meta- analysis (14 cohort studies including 3566 patients)
5 yr mortality rates were higher for patients with a + CRM
Chan DS, et al. Br J Surg. 2013
Extent of lymphadenectomy
• Debated.
• The minimum number of LN that should be removed has not been established.
• However, as many LN should be removed as is feasible, since more extensive
lymphadenectomy has been associated with better survival [42,119-122].
• In a retrospective review of 972 patients with node-negative esophageal cancer:
5 yr DSS : 55 percent when fewer than 11 nodes were resected,
5 yr DSS : 66 percent for 11 to 17 nodes resected
5 yr DSS : 75 percent for 18 or more nodes resected [119].
The data suggest that the higher number of nodes retrieved correspond to a more
extensive resection.
Greenstein AJ, et al. Cancer 2008
Definitions
• Many high-volume surgical centers routinely perform en bloc esophagectomy
with a two-field (mediastinal, upper abdomen) LN dissection.
• 3 field lymphadenectomy of the mediastinal, abdominal, and cervical nodes, is
commonly practiced in Asian countries for upper thoracic esophageal cancers.
• In a retrospective review of 1361 patients with SCC of the thoracic esophagus, the
frequency of nodal metastasis was
Neck (9.8 percent)
Upper mediastinum (18.0 percent)
Middle mediastinum (18.9 percent)
Lower mediastinum (11.8 percent)
Upper abdomen (28.4 percent)
Li B, Chen H, et al. J Thorac Cardiovasc Surg. 2012
• Proponents of extended lymphadenectomy emphasize the relationship between
total LN count and prognosis and quote long-term OS as evidence of its
therapeutic benefit.
• Atorki et al: 80 patients underwent 3 field LAD.
5 yr OS was 51 % (88 % for node-negative and 33% for node-positive).
• Unsuspected metastases in the RLN or cervical nodes were detected in 36 % of
pts.
• The location of the tumor (upper versus middle to lower-third) may have an
influence on the frequency of finding cervical nodal metastases.
• At least two randomized trials have compared different extents of
lymphadenectomy during esophageal cancer surgery.
Neither provided a conclusive result as to the benefit of 3 field LAD.
• In the US, en bloc resection of the mediastinal and upper abdominal lymph nodes
is considered a standard component of transthoracic esophagectomy.

2 field vs 3 field
Hand-sewn versus stapled anastomosis
• Hand-sewn (single versus double layer) vs Stapled (circular versus
side-to-side linear) vs Hybrid linear stapled technique,
• Surgeon experience : most important determinant at present.
Meta-analysis (12 RCTs with 1407 patients):
(Circular stapled vs hand sewn)
• Similar rate of anastomotic leak.
• More strictures with circular stapler.
A hybrid linear stapled technique (modified Collard
technique)
65 % increase in the anastomotic cross-sectional area
Reduced morbidity.
In a review of 274 patients (Hybrid i.e modified Collard
technique vs hand sewn), the pts with hybrid
anastomosis had:
Less cervical wound infections (8 versus 29 percent) .
Similar leak rate
Fewer anastomotic dilatations (4 versus 11%,
mean 2.4 versus 4.1 per patient, respectively).

Cervical versus thoracic anastomosis
• Equally safe when performed using standardized techniques.
• At present, the choice of anastomotic location remains clinician
dependent.
• A cervical anastomosis has a higher leak rate and risk of injury to the
RLN.
• However, the anatomic confines of the neck and thoracic inlet limit
surrounding tissue contamination and, thus, limit morbidity.
• 4 clinical trials (267 patients) : 132 cervical anastomosis vs thoracic
anastomosis
• Cervical anastomosis were associated
• Higher rate of anastomotic leak (18 versus 4 %).
• Significantly higher rate of RLN injury (OR 7.14, 95% CI 1.75-29.14)
• No difference in rate of pulmonary complications, perioperative
mortality, benign stricture formation, or tumor recurrence at the
anastomotic site.
Orthotopic placement
• Orthotopic placement is generally preferred.
• A meta-analysis of trials comparing the posterior mediastinal route
and the retrosternal route was unable to demonstrate any difference
in postoperative morbidity .
• Other series revealed a higher anastomotic leak rate in the
retrosternal route, likely due to increased length requirements for the
conduit as well as compression.

Role of pyloroplasty or pyloromyotomy
Meta-analysis:
9 trials and 553 esophagectomy patients
Randomized to pyloromyotomy vs none
Lower risk of GOO for patients with a
pyloromyotomy (p <0.046).
No difference for:
Operative mortality
Anastomotic leaks
Pulmonary morbidity
Fatal pulmonary aspiration.
Urschel JD, et al. Dig Surg. 2002
Prospective study :
N = 242 patients
Group A : No pyloromyotomy (n = 83)
Group B : Pyloromyotomy (n = 159)
Results:
Pyloromyotomy does not reduce the
incidence of symptomatic DGE.
(Group A 9.6% vs Group B 18.2%, p=0.078).
Post-operative GOO can be effectively
managed with endoscopic pyloric dilatation.

Recurrent laryngeal nerve identification
• Injury can occur during cervical or upper thoracic dissection.
• Incidence: 2-17 %
• More common when a cervical approach is utilized.
• Principles
Precise knowledge of cervical esophageal
anatomy.
Plane of dissection should be as close as possible to
the esophagus.
Avoidance of metal or rigid retractors along the TE
groove.
Orringer MB, et al. Ann Surg. 2007
Jejunal feeding tube placement
• A feeding jejunostomy tube is inserted at the time of the surgical
resection for all patients undergoing an esophagectomy and for select
patients who require nutritional support during induction
chemotherapy and/or radiation therapy.
• The jejunostomy tube is inserted 40 cm distal to the ligament of
Treitz, using either a laparoscopic approach if technically feasible or
through a small laparotomy incision.
POSTOPERATIVE MANAGEMENT
• Enteral feedings are started on POD 2 and slowly advanced.
• OGS is performed on POD 7 to evaluate for leak and emptying of the conduit.
• The NG tube generally remains in place until OGS is performed and demonstrates no leak.
• Minimal liquid diet for approximately 2 weeks.
• Postoperative thromboprophylaxis : Controversial
High risk procedure :Postoperative thromboprophylaxis is recommended (The American College of
Chest Physicians Guidelines on the Prevention of VTE)
High risk of bleeding : Especially in the setting of blunt mediastinal dissection, and thus argue for less
aggressive prophylaxis.
Frequent use of neuraxial anesthesia, which further limits the use of perioperative anticoagulants for
thromboprophylaxis .
Unfortunately, a paucity of data exists to help clarify these issues, and, therefore, clinical practice
varies.

Early Feeding after Esophagectomy
MORBIDITY AND MORTALITY
• The overall incidence of postoperative complications varies widely
between 20 and 80 percent
• Includes systemic complications (eg, pneumonia, myocardial
infarction) and complications specific to the surgical procedure (eg,
anastomotic leaks, recurrent laryngeal nerve injury).
• Pulmonary complications : mc (16 – 67%), mc of mortality.
• Anastomotic leak is the most dreaded (0-40%)
• The overall in-hospital mortality rates range from 0 to 22 percent.
• The overall 30-day mortality rates (excluding in-hospital deaths) is <1
to 6 percent.
Systemic complaints
Pulmonary
MC (16 to 67%)
60% of mortality
Cardiac
AF: 20%
MI: 1.1-3.8%
Anastomotic leak — 5-40 %,
Mortality a/w with leaks: 2-12 %.
Factors affecting leaks:
Anastomotic technique
Location (neck vs chest)
Type of conduit (stomach vs colon vs small bowel)
Location of the conduit (orthotopic vs heterotopic)
Other Risk Factors:
Conduit ischemia
Neoadjuvant therapy
Comorbid conditions like heart failure,
hypertension, renal insufficiency.
Type of procedure
M/M
Neck leaks : Wound m/m
Thoracic leaks: Re-exploration, Endoscopic
stenting or clips, transluminal vacuum therapy
Conduit ischemia — 9%
Minor leak to, rarely, complete loss of the
conduit.
Rate of ischemia similar for gastric pull-up &
colonic interposition graft (10.4 vs 7.4 %).
Total conduit ischemia: Rapidly deteriorating
course with septic shock.
Mandates aggressive resuscitation, surgical
removal, drainage and proximal esophageal
diversion, broad-spectrum antibiotic
coverage.
Anastomotic stricture : 9 to 40 %
Linked to conduit malperfusion/ischemia or
surgical technique. Endoscopic dilatation.
RLN injury — Hoarseness, dyspnea, and/or
aspiration pneumonia.
Laryngoscopy and esophageal swallow
evaluation.
More common in cervical anastomosis and
3-field lymphadenectomy.
Management of a laterally paralyzed cord
requires vocal cord injection or temporary
vocal cord medialization.
Chylothorax — 0 to
8% . 18% mortality
rates and 85% major
30-day complication.
Diagnosis : High
chest tube output
(milky)
TGs >110,
chylomicrons +
M/M: Parenteral nutrition +octreotide + fluid resuscitation.
Early surgical intervention (within 14 days from diagnosis) is favored if it
persists (>10 mL/kg for 5 days)
If the site of the leak is not identified, ligation of all tissue between the spine
and the aorta is performed as caudal as possible in the right hemithorax.
QUALITY OF LIFE
• Temporary and long-term detrimental impacts on HR-QOL.
• Recovery seems to occur within 12 to 24 months.
• Long-term survivors still report residual problems with eating,
breathlessness, diarrhea, reflux, fatigue, and odynophagia even after 3-4
years.
• Recovery of HR-QOL may be to the occurrence of postoperative
complications.
• Patients who sustained a major postoperative complication (eg,
pneumonia, anastomotic leak) had significant more dyspnea, fatigue and
eating restrictions.
Derogar M,et al. Influence of major postoperative complications on health-related quality of life among long-term survivors of esophageal
cancer surgery. J Clin Oncol. 2012
Centralization of Esophageal surgery
• Lower mortality rates and better clinical outcomes in large volume
centres compared with lower-volume institutions.
• The definition of low versus high volume is variable, with most studies
defining "low volume" as <4 to <10 procedures and "high volume" as
>9 to >40 procedures.
• As an example, in one report that used Medicare claims data, the
mortality following esophagectomy at the highest-volume hospitals
(>19 procedures annually) was significantly lower compared with the
lowest-volume hospitals (<2 procedures annually)

Esophagectomy : APPROACHES, CONTROVERSIES AND CURRENT EVIDENCE

  • 1. ESOPHAGECTOMY : SURGICAL APPROACHES AND CURRENT EVIDENCE DR AMIT DANGI
  • 2. • Localized disease : 22 percent of all cases [1]. • Regional disease : 30 percent of patients. • Goal of surgical management is curative. • Surgical resection is the traditional mainstay of multidisciplinary therapy for patients with localized disease [2-5]. • The clinical spectrum of esophageal cancer has changed over the last few decades, with an increase in incidence of adenocarcinoma and a decrease of squamous cell carcinoma [6-11]. • Surgical management is independent of histology.
  • 3. ANATOMY • 25 to 30 cm in length • Posterior mediastinum. • C6-T11
  • 4.
  • 5. Anatomy of esophageal cancer primary site, including typical endoscopic measurements of each region measured from the incisors. Exact measurements depend on body size and height. For tumors of the EGJ and cardia, location of cancer primary site (ie, esophagus, stomach) is defined by cancer epicenter. Divided into 4 anatomic areas • Cervical • Thoracic • Lower thoracic/Esophagogastric junction • Abdominal esophagus (figure 4 and figure 5 and figure 6).
  • 6.
  • 7. • The esophagus is composed of the mucosa, submucosa, muscularis externa, and adventitia (image 1). • There are three critical anatomic points of narrowing: Cricopharyngeus , Broncho-aortic constriction, Esophagogastric junction. • These are also the most common sites of iatrogenic and mechanical perforation (figure 7 and figure 8) [12].
  • 8. BLOOD SUPPLY Arterial supply: • Inferior thyroid artery (cervical esophagus), • Bronchial arteries, and the aorta (thoracic esophagus) • Branches of the LGA and inferior phrenic artery (abdominal esophagus). Venous drainage: • Inferior thyroid vein (cervical esophagus); • Aygous vein, the hemiazygous vein, or the bronchial veins (thoracic esophagus); • Coronary vein (abdominal esophagus)
  • 9. LYMPHATIC SUPPLY • Rich network of submucosal lymphatic that facilitate the longitudinal spread of neoplastic cells along the esophageal wall. • Lymphatic drainage is to cervical nodes, tracheobronchial and mediastinal nodes, and gastric and celiac nodes. • An important point is that the regional lymph nodes for all locations in the esophagus, including the cervical esophagus and esophagogastric junction, extend from the periesophageal cervical nodes to celiac nodes.
  • 10. HISTOLOGY OF ESOPHAGEAL CANCER SQUAMOUS CELL CARCINOMA • SCC arises from the cells that line the upper part of esophagus. • Smoking and alcohol • Dietary factors : Alfatoxin, hot beverages, N nitroso compounds, areca nut, red meat, low selenium, zinc deficiency • Underlying disease: Achalasia : 16 fold Corrosive ingestion • Prior gastrectomy or Atrophic gastritis • HPV • Tylosis • Oral bisphosphonates • Poor oral hygiene ADENOCARCINOMA • Adenocarcinoma arises from glandular cells that are present at the GEJ. • Barrett Metaplasia : 30 fold • GERD • Obesity and metabolic syndrome • Smoking • No association with alcohol
  • 11.
  • 12. TNM STAGING (8th edition 2017) • Recognizes biologic heterogeneity and provides separate stage groupings for adenocarcinoma and SCC. • Tumors involving the EGJ with the tumor epicenter no more than 2 cm into the proximal stomach are staged as esophageal cancers. • In contrast, EGJ tumors with their epicenters located more than 2 cm into the proximal stomach are staged as stomach cancers, as are all cardia cancers not involving the EGJ, even if they are within 2 cm of the EGJ. • Thus, regardless of histology and Siewert type, esophageal tumors arising in the cervical, thoracic esophagus or abdominal esophagus, and those involving the EGJ that have an epicenter within 2 cm of the EGJ share the same criteria for T stage, N stage, and M stage designation
  • 13.
  • 14.
  • 15. PRETREATMENT EVALUATION Endoscopic biopsy : 98% diagnosis with 7 biopsies (100% if brush cytology added) Computed tomography (CT) of the neck, chest and abdomen. Endoscopic ultrasound (EUS) : Preferred for loco-regional staging. Positron emission tomography (PET): Detect occult mets in 20% Diagnostic laparoscopy and thoracoscopy : Selective use, invasive, more accurate than CT or EUS alone, no comparison with EUS + PET/CT Brochoscopy and VDL.
  • 16. SUV which reflects the metabolic activity of the tumor may also serve as a prognostic factor. A high SUV predicted a worse survival. However, some studies suggested a better response to NACRT in this group, but is uncertain. Suspicious PET findings should be confirmed with biopsy before excluding a patient from surgical consideration, given the high rate of false-positive findings. Detect occult mets after CRT or induction CT in approx 8% of patients.
  • 17. Role of Diagnostic laparoscopy NCCN Consider DL to be "optional" for patients with EGJ tumors and no evidence of metastatic disease. ESMO Advocate DL for all patients with locally advanced (T3/T4) adenocarcinomas of the EGJ infiltrating the gastric cardia. SAGES Early stage esophageal cancer with no evidence of distant or LN metastases on high- quality preoperative imaging), who are considered for curative resection may benefit from staging laparoscopy (grade B). The need for diagnostic laparoscopy for patients who appear to have potentially resectable distal esophageal and EGJ adenocarcinomas is controversial.
  • 18. IMPORTANCE OF PRE-TREATMENT STAGING ASSESSMENT • T1N0 : High cure rate from surgical or endoscopic therapy alone. • Surgery: Primary curative modality for both esophageal and EGJ cancers that have invaded through the esophageal wall or are node positive : Poor long-term outcome with resection alone (even R0). • T3 or N+ tumors: NACRT is generally preferred over initial surgery. • Optimal approach to clinical T2N0 disease is debated. • NCCN suggest NACRT for clinical T2N0 adenocarcinomas of the distal esophagus and EGJ, and initial resection for clinical T2N0 SCC if they are <2 cm and well differentiated. • Regardless of histology, between 50 and 80 percent of patients with esophageal and EGJ cancers present with incurable, locally advanced unresectable or metastatic disease.
  • 19. Criteria for resection Esophagectomy as first line of therapy ● cT1N0M0 lesions ● cT2N0M0 lesions are candidates in many medical centers Esophagectomy following NACT/NACRT ● Patients with thoracic esophageal or EGJ tumors and full-thickness (T3) involvement of the esophagus with/without nodal disease. ● cT4a disease with invasion of local structures (pericardium, pleura, and/or diaphragm only) that can be resected en bloc, and who are without evidence of metastatic disease to other organs (eg, liver, colon).
  • 20. cPR • Surgical resection is recommended. • cPR seen in 20-25% of patients. • However, it is not possible to reliably identify these patients either by EUS or repeat PET scan. • The recommendation is to proceed with resection if the patient is fit for surgery and has not progressed during chemoradiotherapy
  • 21. Surgery after NACRT • The impact of NACT/NACRT on perioperative morbidity and mortality was addressed in a meta-analysis of 23 randomized trials comparing neoadjuvant therapy versus surgery alone or NACT versus CRT [16]. • Neither NACT/NACRT increased the risk of total postoperative mortality or morbidity. • However, subgroup analysis suggested that patients undergoing NACRT for SCC might be at an elevated risk for postoperative mortality relative to those treated by surgery alone (risk ratio 1.95, 95% CI 1.06-3.6).
  • 22. Relative contraindications ● Advanced age ● Comorbid illness Indicators of unresectability — • Metastatic disease • Extra-regional LN spread (eg, paraaortic or mesenteric lymphadenopathy). • The regional lymph nodes for all locations in the esophagus, including the cervical and EGJ, extend from the periesophageal cervical nodes to celiac nodes. • Celiac nodal metastases and mediastinal/supraclavicular nodes are scored as regional nodal disease TNM staging system, regardless of the primary tumor location. • Number rather than location of involved LN determines the N stage
  • 23. (A-C) Lymph node maps for esophageal cancer. Regional lymph node stations for staging esophageal cancer from left (A), right (B), and anterior (C).
  • 24. PREOPERATIVE OPTIMIZATION • PREOPERATIVE RESPIRATORY REHABILITATION —A retrospective cohort study of 100 patients undergoing an esophagectomy found that patients managed with preoperative respiratory rehabilitation (n = 63) for seven days had a lower rate of postoperative pulmonary complications (6 versus 24 percent) [18]. • NUTRITION AND IMMUNONUTRITION-
  • 26. Cervical esophageal cancer resection • CRT : Primary modality • Surgical resection : Patients who fail CRT, or who opt for a surgical resection. • Resection usually requires removal of portions of the pharynx, the larynx, the thyroid gland, and portions of the proximal esophagus. • Single stage, three-phase operation requires cervical, abdominal, and thoracic incisions. • Permanent terminal tracheostomy. • Bilateral radical neck dissections are generally performed [19-29]. • Restoration of GIT continuity with a gastric pull-up and anastomosis to the pharynx. • Free jejunal interposition graft or a deltopectoral or pectoralis major myocutaneous flap are alternative reconstructive options.
  • 27. Thoracic cancer resection • EAC and SCC involving the middle or lower third of the esophagus (except GEJ cancers), generally requires total esophagectomy (submucosal skip lesions) [30- 32]. • In selected superficial or early invasive esophageal cancer arising distally in the setting of BE, a more limited resection can be performed. • Optimal surgical approach : Unknown [33-35]. • Choice of surgical approach depends upon many factors: ● Tumor location, length, submucosal extension, and adherence to surrounding structures ● The type or extent of lymphadenectomy desired ● The conduit to be used to restore GIT ● Postoperative bile reflux ● The preference of the surgeon
  • 28. • The THE, Ivor-Lewis (TTE), and tri-incisional esophagectomy (McKeown) procedures are the most commonly performed esophagectomies in North America. • Extended (three-field) lymphadenectomy is commonly performed in Asia [36-42]. • Gastric interposition: preferred conduit • Jejunum or the colon can also be used as the conduit [43-47]. • These conduits are resistant to the effects of gastric acid, and they have a shape similar to the native esophagus.
  • 29. Transhiatal esophagectomy • Cervical, thoracic, and EGJ cancers. • Upper midline laparotomy incision and a left neck incision[48,49]. • Blunt dissection of thoracic esophagus. • Cervical anastomosis with a gastric pull-up. • Disadvantages: Limited thoracic lymphadenectomy and blind midthoracic dissection. • In the largest prospective database series of 2007 patients, the in-hospital mortality rate decreased in the 1998 to 2006 cohort (n = 944 patients) compared with the 1976 to 1998 cohort (1 versus 4 percent) [50]. • The anastomotic leak rate was also lower in the 1998 to 2006 cohort (9 versus 14 percent). • Other postoperative complications included atelectasis and pneumonia (2 percent), and intrathoracic hemorrhage, RLN paralysis, chylothorax, and tracheal laceration in <1 percent each. Orringer MB, et al. Ann Surg. 2007
  • 30. Ivor-Lewis transthoracic esophagectomy • Lower third of the esophagus. • Not the optimal approach for cancers located in the middle third because of the limited proximal margin that can be achieved. • Combines a laparotomy with a right thoracotomy and an intrathoracic anastomosis. • Direct visualization of the thoracic esophagus & allows a full thoracic lymphadenectomy. • Minimally invasive Ivor-Lewis approach to a thoracotomy. • Disadvantages : Limited length of proximal esophagus that can be resected to achieve a R0, Intrathoracic anastomosis. 3 to 20 percent risk of severe bile reflux [51,56]. Higher morbidity (64%) and mortality associated with leak [57-62]. With current technique, mortality rates are substantially lower [63].
  • 31. Modified Ivor-Lewis transthoracic esophagectomy Left thoracoabdominal incision (single incision) Gastric pull-up and an esophagogastric anastomosis in the left chest [77]. Most useful for tumors involving the GEJ. Disadvantages include a high incidence of complications such as postoperative reflux and limitation of the proximal esophageal margin by the aortic arch.
  • 32. Tri-incisional esophagectomy • Combines the THE and TTE approaches (MIS can be perfomed) • Transthoracic total esophagectomy with a thoracic lymphadenectomy and cervical anastomosis [78-82]. • Allows a complete 2-field (mediastinal and upper abdominal) lymphadenectomy under direct vision. • Advantages of a neck anastomosis : Easier management of a possible leak Lower reflux More extensive proximal resection margin Location outside of radiation ports if administered preoperatively.
  • 33. Oncological principles 1. Thoracotomy A right posterolateral thoracotomy or a thoracoscopy is performed to assess resectability and exclude local invasion of contiguous structures. En bloc resection is performed 2. Laparotomy Metastatic disease is excluded, and the stomach is mobilized with construction of conduit. 3. Neck incision – Left neck exposure preferred. Left RLN recurs lower (around the aortic arch) than the right RLN, which recurs around the subclavian artery and is therefore more likely to be injured from a right neck approach.
  • 34.
  • 36. EGJ cancer resection • Surgical management is standard of care includes either an esophagectomy with partial or extended gastrectomy, with/out thoracotomy. • Principles: R0 resection, 4-cm (distal) gastric margin, 5-cm esophageal margin, and Resection of at least 15 nodes in basins appropriate for the primary tumor. • Solely transabdominal approach without thoracoabdominal incision or THE is not acceptable for tumors that involve the distal esophagus. Siewert JR, et al. Chirurg 1987
  • 37. • The contemporary operative approach for EGJ cancer is based upon findings of 2 phase III trials. ● A Japanese trial (JCOG 9502) Compared THE vs extended esophagectomy using a left thoracoabdominal approach (LTA) for patients with Sievert type II or III adenocarcinoma. THE gp: Received a total gastrectomy plus a D2 lymphadenectomy (including splenectomy) and PALND. LTA gp: Underwent thorough mediastinal nodal dissection below the left IPV + D2 abdominal LAD. The trial closed prematurely when a planned interim analysis concluded that it was unlikely that LTA would be significantly better than TH. • 5 yr OS was lower in the LTA group (38 vs 52 %, p>0.05), • 10 yr OS: 24 versus 37 percent (p>0.05)[89]. • More complications and mortality in LTA gp. • Conclusion: LTA could not be recommended for type II/III tumors. ● A phase III Dutch trial N=220 patients with Siewert type I or II adenocarcinoma Assigned to a. THE b. Extended thoracic resection (TTE) with an extended en bloc lymphadenectomy via the right thoracic approach [RTA]) [73,86]. • Similar In-hospital mortality. • More pulmonary complications and postoperative chylous leakage after RTA. • More ICU and total hospital stays in RTA group [86]. • Similar 5 yr OS (36 versus 34 percent for RTA and THE) • Better survival with extended thoracic resection in the patients with a type I tumor (five-year survival 51 versus 37 percent, p = 0.33). • Conclusions : Given the greater hazards a/w with extended transthoracic resection, it could only be recommended for patients with type I and not type II tumors.

  • 39. Open versus minimally invasive Advantages of MIS include : ● Smaller incisions ● Less blood loss ● Fewer postop complications ● Shorter ICU and hospital stay ● Better preservation of postoperative pulmonary function Areas of uncertainty include: ● Optimal minimally invasive procedure ● Adequacy of the esophageal and gastric surgical margins ● Extent of LN dissection ● Safety of minimally invasive esophagectomy in patients who have undergone preoperative radiation therapy ● Long-term oncologic outcomes
  • 40. Safety of MIS Esophagectomy • No consensus that MIE is associated with a decrease in 30-day mortality and overall morbidity, as found in many retrospective and prospective studies:
  • 41. n=75,502 Esophagectomy n = 1155 : MIE • No significant benefits as defined by a decrease in 30-day mortality and overall morbidity (4.3 versus 4.0 percent and 38.0 versus 39.2 percent, respectively). • The re-intervention rate was significantly higher for patients undergoing an MIE compared with an open esophagectomy (21.0 versus 17.6 percent).
  • 42. A prospective TIME trial found that patients undergoing an MIE have a better perioperative hospital course. N=115 Patients undergoing an MIE had • Lower rate of in hospital pulmonary infections (12 vs 34%) • Lower perioperative (within 2 weeks) pulmonary infections (9 vs 29%). • Similar DFS (36 versus 40 percent) and 3 yr OS (40 versus 51 percent)
  • 43. 12 studies N = 672 MIE or hybrid minimally invasive esophagectomy (HMIE) N = 612 Open esophagectomy No significant difference in • 30-day mortality. • Frequency of anastomotic leak MIS procedures were associated with • Significantly lower blood loss • Shorter ICU and hospital stay • Fewer respiratory complications. • 50 % reduction in total morbidity. • Total morbidity was similar for HMIE procedure and open esophagectomy.
  • 44. • Lap THE was associated with Fewer overall complications (risk ratio 0.64, 95% CI 0.48-0.86) Fewer serious complications (risk ratio 0.49, 95% CI 0.24-0.99) Shorter hospital stays (by three days). However, RCTs are needed to determine the optimal approach to THE.
  • 45. Total MIE approach • Limited data for oncologic outcomes. • In the largest series with oncologic outcomes, 70 of 77 attempts to perform a total MIE were successful. 2 yr OS and DFS were 81 and 74 %, respectively. Recurrence was documented in 14 patients, 11 of which were distant recurrences. • No RCTs comparing any form of MIE to an open procedure. • However, a retrospective Australian series compared outcomes among • 114 patients : open esophagectomy, • 309 patients; Thoracoscopic-assisted surgery (TAS) • 23 patients : Total MIE While the data suggest potential for a total MIE approach, this cannot be considered a standard approach. Berrisford RG, et al; Br J Surg 2008; 95:602. Smithers BM, et al.. Ann Surg 2007; 245:232. No differences in the rate of margin positivity or the no of LN retrieved, No difference in the time to recurrence or median or 3 yr OS (compared stage for stage).
  • 46. Combined approach • Thoracoscopic mobilization of the esophagus + node dissection combined with open laparotomy. • Most popular MIE technique with the most extensive published experience. • Relative C/I to thoracoscopic surgery include Inadequate pulmonary function, Extensive pleural adhesions, Prior pneumonectomy, Bulky tumors, Locally infiltrative tumors, particularly those with airway involvement Santillan AA, et l.

  • 47. Circumferential resection margin • Unclear prognostic role till recently • The College of American Pathologists (CAP) defines a positive CRM as the presence of esophageal cancer at the resection margin. • The United Kingdom Royal College of Pathologists (RCP) defines a positive CRM as the presence of esophageal cancer within 1 mm of the resection margin. • CAP criteria differentiate a higher-risk group of patients with resectable esophageal cancer than the RCP criteria. • Meta- analysis (14 cohort studies including 3566 patients) 5 yr mortality rates were higher for patients with a + CRM Chan DS, et al. Br J Surg. 2013
  • 48. Extent of lymphadenectomy • Debated. • The minimum number of LN that should be removed has not been established. • However, as many LN should be removed as is feasible, since more extensive lymphadenectomy has been associated with better survival [42,119-122]. • In a retrospective review of 972 patients with node-negative esophageal cancer: 5 yr DSS : 55 percent when fewer than 11 nodes were resected, 5 yr DSS : 66 percent for 11 to 17 nodes resected 5 yr DSS : 75 percent for 18 or more nodes resected [119]. The data suggest that the higher number of nodes retrieved correspond to a more extensive resection. Greenstein AJ, et al. Cancer 2008
  • 50. • Many high-volume surgical centers routinely perform en bloc esophagectomy with a two-field (mediastinal, upper abdomen) LN dissection. • 3 field lymphadenectomy of the mediastinal, abdominal, and cervical nodes, is commonly practiced in Asian countries for upper thoracic esophageal cancers. • In a retrospective review of 1361 patients with SCC of the thoracic esophagus, the frequency of nodal metastasis was Neck (9.8 percent) Upper mediastinum (18.0 percent) Middle mediastinum (18.9 percent) Lower mediastinum (11.8 percent) Upper abdomen (28.4 percent) Li B, Chen H, et al. J Thorac Cardiovasc Surg. 2012
  • 51. • Proponents of extended lymphadenectomy emphasize the relationship between total LN count and prognosis and quote long-term OS as evidence of its therapeutic benefit. • Atorki et al: 80 patients underwent 3 field LAD. 5 yr OS was 51 % (88 % for node-negative and 33% for node-positive). • Unsuspected metastases in the RLN or cervical nodes were detected in 36 % of pts. • The location of the tumor (upper versus middle to lower-third) may have an influence on the frequency of finding cervical nodal metastases. • At least two randomized trials have compared different extents of lymphadenectomy during esophageal cancer surgery. Neither provided a conclusive result as to the benefit of 3 field LAD. • In the US, en bloc resection of the mediastinal and upper abdominal lymph nodes is considered a standard component of transthoracic esophagectomy.

  • 54. Cervical versus thoracic anastomosis • Equally safe when performed using standardized techniques. • At present, the choice of anastomotic location remains clinician dependent. • A cervical anastomosis has a higher leak rate and risk of injury to the RLN. • However, the anatomic confines of the neck and thoracic inlet limit surrounding tissue contamination and, thus, limit morbidity.
  • 55. • 4 clinical trials (267 patients) : 132 cervical anastomosis vs thoracic anastomosis • Cervical anastomosis were associated • Higher rate of anastomotic leak (18 versus 4 %). • Significantly higher rate of RLN injury (OR 7.14, 95% CI 1.75-29.14) • No difference in rate of pulmonary complications, perioperative mortality, benign stricture formation, or tumor recurrence at the anastomotic site.
  • 56. Orthotopic placement • Orthotopic placement is generally preferred. • A meta-analysis of trials comparing the posterior mediastinal route and the retrosternal route was unable to demonstrate any difference in postoperative morbidity . • Other series revealed a higher anastomotic leak rate in the retrosternal route, likely due to increased length requirements for the conduit as well as compression.

  • 60. POSTOPERATIVE MANAGEMENT • Enteral feedings are started on POD 2 and slowly advanced. • OGS is performed on POD 7 to evaluate for leak and emptying of the conduit. • The NG tube generally remains in place until OGS is performed and demonstrates no leak. • Minimal liquid diet for approximately 2 weeks. • Postoperative thromboprophylaxis : Controversial High risk procedure :Postoperative thromboprophylaxis is recommended (The American College of Chest Physicians Guidelines on the Prevention of VTE) High risk of bleeding : Especially in the setting of blunt mediastinal dissection, and thus argue for less aggressive prophylaxis. Frequent use of neuraxial anesthesia, which further limits the use of perioperative anticoagulants for thromboprophylaxis . Unfortunately, a paucity of data exists to help clarify these issues, and, therefore, clinical practice varies. Geerts WH, Bergqvist D, Pineo GF, et al.

  1. Although there seems to be little doubt that esophageal SCCs and adenocarcinomas represent two different diseases with characteristic pathogenesis, epidemiology, tumor biology, and outcomes, whether and how histology should influence the therapeutic approach remains controversia Squamous cell carcinoma (SCC) and adenocarcinoma account for over 95 percent of esophageal malignant tumors. For most of the 20th century, SCC has predominated. In the 1960s, SCC accounted for more than 90 percent of all esophageal tumors in the United States, and adenocarcinomas were considered so uncommon that some authorities questioned their existence. However, over time, the incidence of esophageal adenocarcinoma (predominantly arising in the distal esophagus and esophagogastric junction) has increased dramatically in Western countries such that adenocarcinoma now accounts for >60 percent of all esophageal cancers in the United States [1]. In contrast, worldwide, SCC still predominates [2].

Although there seems to be little doubt that esophageal SCCs and adenocarcinomas represent two different diseases with characteristic pathogenesis, epidemiology, tumor biology, and outcomes, whether and how histology should influence the therapeutic approach remains controversia The role of chronic reflux as an independent risk factor for esophageal adenocarcinoma has not been well defined since more than 50 percent of cases of adenocarcinoma have no history of symptomatic reflux disease
  3. The highest rates of SCC are found in Northern Iran, Central Asia, and North-Central China (the so-called "esophageal cancer belt" Squamous cell carcinoma (SCC) and adenocarcinoma account for over 95 percent of esophageal malignant tumors. For most of the 20th century, SCC has predominated. In the 1960s, SCC accounted for more than 90 percent of all esophageal tumors in the United States, and adenocarcinomas were considered so uncommon that some authorities questioned their existence. However, over time, the incidence of esophageal adenocarcinoma (predominantly arising in the distal esophagus and esophagogastric junction) has increased dramatically in Western countries such that adenocarcinoma now accounts for >60 percent of all esophageal cancers in the United States [1]. In contrast, worldwide, SCC still predominates [2].
  4. The tumor, node, metastasis (TNM) staging system of the combined American Joint Committee on Cancer (AJCC)/Union for International Cancer Control (UICC) for esophageal cancer is used universally. In the most recent (2017, eighth edition) revision [15,16], tumors involving the EGJ with the tumor epicenter no more than 2 cm into the proximal stomach are staged as esophageal cancer. In contrast, EGJ tumors with their epicenter located more than 2 cm into the proximal stomach are staged as stomach cancers, as are all cardia cancers not involving the EGJ, even if they are within 2 cm of the EGJ. Thus, regardless of histology, all esophageal tumors arising in the cervical, thoracic, or abdominal esophagus and those involving the EGJ that have an epicenter within 2 cm of the EGJ (table 4) share the same criteria for T, N, and M stage designation. However, there are separate stage groupings for SCC and adenocarcinoma, regardless of site, and stage groupings also differ according to whether the patient has been treated prior to surgery (the yp designation) (table 5).
  5. Prior to 2010, the specific lymph node groups that were considered regional for esophageal cancer varied according to the anatomic compartment and location within the esophagus. Data suggesting the prognostic importance of the number of involved lymph nodes rather than the location (particularly in the surgical specimen after chemoradiotherapy [24-32]) led to a change in the N stage classification in the 2010 (and subsequent 2017) revision of the AJCC/UICC staging system, with an emphasis on the number of involved nodes rather than location. Regional lymph nodes for all locations in the esophagus extend from periesophageal lymph nodes to celiac nodes and are illustrated in the figure (figure 4).
  6. Histology-specific stage groupings for adenocarcinoma and SCC, which were initially introduced in 2010, were based on an analysis of worldwide data on 4627 patients with cancer of the esophagus or EGJ who underwent surgery alone; among patients with node- negative tumors, prognosis was dependent on not only T stage but also histology and grade of differentiation, and for SCCs, tumor location [17].
  7. Precise pretreatment staging guides multidisciplinary management decisions, including a surgical resection [7]. It includes: For patients with a thoracic esophageal tumor at or above the carina, bronchoscopy is indicated. For cervical squamous cell carcinomas (SCCs), flexible laryngoscopy to assess local disease spread and exclude a synchronous malignancy of the head and neck is generally recommended. The most common sites of distant metastases in patients with esophageal cancer are the liver, lungs, bone, and adrenal glands [8]. Adenocarcinomas most frequently metastasize to intraabdominal sites (liver, peritoneum), while metastases from SCCs are usually intrathoracic.
  8. The need for diagnostic laparoscopy for patients who appear to have potentially resectable distal esophageal and EGJ adenocarcinomas is controversial. The need for diagnostic laparoscopy for patients who appear to have potentially resectable esophageal or EGJ carcinomas is controversial, and there is no consensus on this issue from expert groups. We reserve diagnostic laparoscopy for patients who, after conventional pretreatment staging studies, appear to have potentially resectable, clinical T3 or T4 (table 3), Siewert II to III (ie, located between 1 cm proximal and 5 cm distal to the anatomical squamocolumnar junction or Z-line (figure 5)) adenocarcinomas of the EGJ, or if there is suspicion for intraperitoneal metastatic disease that cannot otherwise be confirmed. We do not perform thoracoscopic staging in patients who have access to EUS and PET/CT.
  9. — It is vitally important that patients with newly diagnosed esophageal cancer be accurately staged prior to treatment in order to select the appropriate treatment strategy. ● For patients with apparently localized, potentially resectable tumors, the choice of initial treatment is highly dependent on pretreatment staging: Guidelines from expert groups differ. Some suggest initial resection regardless of histology [4]. Others, including the National Comprehensive Cancer Network (NCCN), suggest upfront chemoradiotherapy for clinical T2N0 adenocarcinomas of the distal esophagus and EGJ, and initial resection for clinical T2N0 squamous cell carcinomas as long as they are <2 cm and well differentiated. Thus, the appropriate selection of patients for palliative treatment, chemoradiotherapy, perioperative chemotherapy, or surgery/endoscopic therapy alone is highly dependent upon accurate preoperative assessment of disease stage.
  10. Patients with esophagogastric junction adenocarcinomas might also be considered for upfront chemotherapy alone if they cannot tolerate trimodality therapy, or if there is a high clinical suspicion of occult metastatic disease.
  11. For patients undergoing chemoradiotherapy for potentially resectable disease who have a clinical response, the necessity of subsequent surgery following NACRT is debated. Surgical resection is recommended , particularly for patients with adenocarcinoma, because of the higher local control rates and lesser need for palliative procedures when surgery is a component of therapy.
  12. ●  Advanced age – Advanced age is associated with greater morbidity following esophagectomy. However, age alone should not determine operability, as selected elderly patients have similar outcomes to younger patients. ●  Comorbid illness – Comorbid illnesses increase the risk of postoperative complications (eg, cardiorespiratory complications, anastomotic leakage, reoperation rates, wound infection) and death following esophagectomy. Obesity is not associated with any increase in overall morbidity following esophagectomy and should not be considered a contraindication for esophagectomy [17].

  14. Intensive preoperative respiratory rehabilitation reduces postoperative pulmonary complications after an esophagectomy.
  15. For tumors confined to the proximal portion of the cervical esophagus, with a sufficient distal resection margin, a free jejunal interposition graft or a deltopectoral or pectoralis major myocutaneous flap are alternative reconstructive options. Free jejunal grafts are advantageous because this approach avoids mediastinal dissection, although expertise in performing microvascular anastomosis is required. Graft necrosis, fistula formation, and later graft strictures are specific problems. When compared with gastric pull-up procedures, graft survival and leakage rates are similar. Alternatively, a transhiatal approach is reasonable.

If a limited resection is performed, intraoperative histologic analysis of the surgical margins must show no evidence of Barrett's changes In selected superficial or early invasive esophageal cancer arising distally in the setting of BE, a more limited resection (eg, an anastomosis in the thorax or a less radical resection such as a THE) can be performed. The optimal surgical approach in these clinical settings is unknown Esophagectomy is a technically difficult operation, and the complication rate is high due to the anatomic challenges of the procedure.
  17. However, their use requires two additional anastomoses; and in the case of the jejunal interposition, the fixed mesenteric length limits transposition to the proximal esophagus.
  18. The thoracic esophagus is bluntly dissected through the diaphragmatic hiatus superiorly and via the neck inferiorly.
  19. This approach permits direct visualization of the thoracic esophagus and allows the surgeon to perform a full thoracic lymphadenectomy. We prefer a minimally invasive Ivor-Lewis approach to a thoracotomy. Many centers report favorable results using the conventional Ivor-Lewis esophagectomy with a right thoracic anastomosis [54,64-70]. Prospective comparisons [55,71-75], plus at least one meta-analysis [76], suggest similar long-term outcomes compared to THE [69]. In one of the largest series of 228 patients undergoing an Ivor-Lewis subtotal esophagectomy, the perioperative mortality rate was 4 percent, and major respiratory and cardiovascular and/or thromboembolic complications occurred in 17 and 7 percent, respectively [69]. Nine patients (4 percent) developed a mediastinal leak, which was anastomotic in five, and due to either an ischemic gastric conduit or gastrotomy dehiscence in the remainder. Only one patient developed a chyle leak. (See "Complications of esophageal resection".)

  20. Left neck exposure is preferred for the esophagogastric anastomosis since this approach reduces the risk of injury to the recurrent laryngeal nerve (RLN) (figure 16) [51,64,65,78,83]. The left RLN recurs lower (around the aortic arch) than the right RLN, which recurs around the subclavian artery and is therefore more likely to be injured from a right neck approach.
  21. An en bloc resection is performed that includes the esophagus and mediastinal (figure 14) and upper abdominal lymph nodes (figure 15), including the right paratracheal, subcarinal, periesophageal, and celiac axis lymph nodes
  22. The extent of the esophageal resection that can be achieved solely via a transabdominal approach without thoracoabdominal incision or transhiatal esophagectomy is limited, and therefore this approach is not accepted for tumors that involve the distal esophagus due to difficulties in achieving an adequate negative proximal margin.
  23. Based upon the results of these, the surgical approach for resection is summarized as follows: ●  Patients with Siewert type I tumors should preferentially undergo a transthoracic en bloc esophagectomy and partial gastrectomy with two-field lymphadenectomy. Lymphadenectomy is important to assess disease stage and evaluate response to neoadjuvant therapy with minimal added risk in morbidity or mortality rates. Other reasonable options include a transhiatal approach, which does not include a lymphadenectomy. ●  Patients with Siewert type II and III tumors should undergo a total gastrectomy with a transhiatal resection of the distal esophagus with lymphadenectomy of the lower mediastinum and an extended lymph node dissection including nodes along the hepatic, left gastric, celiac, and splenic arteries as well as those in the splenic hilum.
  24. — An esophagectomy can be performed as an open or laparoscopic approach. In addition, a minimally invasive esophagectomy (MIE) can be performed by thoracoscopically resecting the thoracic esophagus and mediastinal nodes, in conjunction with a laparoscopic or laparotomy approach to resecting the intra-abdominal esophagus, stomach, and lymph nodes.
  25. The safety of minimally invasive esophagectomy (MIE) was confirmed by several studies [90,91,93-101
  26. from a population- based national data bank
  27. A 3 yr follow-up study showed similar disease-free (36 versus 40 percent) and overall (40 versus 51 percent) three-year survival for patients who underwent open surgery versus MIE [103].
  28. The differences between MIE and HMIE may be attributed to the thoracotomy or laparotomy portion of the procedure.
  29. A 2016 Cochrane systemic review and meta-analysis of six observational studies (five retrospective) concluded that Additionally, laparoscopic transhiatal esophagectomy is only one of the minimally invasive techniques that are used for esophagectomy. Others use various combinations of laparoscopy, thoracoscopy, mediastinoscopy, and robotics to remove esophageal cancers [105]. There is no consistent difference in outcomes for patients with cancer at the esophagogastric junction (EGJ) or intra-abdominal esophagus managed with either an esophagectomy with partial gastrectomy or an extended gastrectomy, with or without thoracotomy
  30. Total minimally invasive esophagectomy (MIE) is technically feasible, but data for oncologic outcomes are limited due to short follow-up and small number of patients evaluated Whether these results are at least as good as those achievable following an open esophagectomy is unclear Additional data, particularly regarding long-term complications and oncologic outcomes, are needed before it can be concluded that results are comparable to those seen with open surgical procedures.
  31. MIE has been associated with less blood loss, less postoperative pain, and decreased intensive care unit and hospital length of stay
  32. Higher 5 yr mortality seen in patients with CRM involvement between 0.1 and 1 mm vs patients with tumor more than 1 mm of the resection margin ( p <0.001).
  33. The appropriate extent of lymphadenectomy during esophageal cancer surgery is debated. The minimum number of LN that should be removed during potentially curative esophagectomy has not been established.
  34. However, while this approach increases the accuracy of staging, whether local control or survival is improved compared with two-field lymphadenectomy is uncertain.
  35. However, since the extent of lymph node dissection can affect the assignment of the final stage of disease, this resulting stage migration phenomenon hampers a stage-by-stage comparison between different forms of surgical resection [125]. In the US, en bloc resection of the mediastinal and upper abdominal lymph nodes is considered a standard component of transthoracic esophagectomy, and a three-field lymphadenectomy is not considered a standard treatment for patients with esophageal cancer. As an example, in one American series of 80 patients undergoing this technique in conjunction with en bloc esophagectomy, the overall five-year survival rate was 51 percent (88 percent for node-negative and 33 percent for node-positive patients). Unsuspected metastases in the RLN or cervical nodes were detected in 36 % of pts
  36. A hybrid linear stapled technique was developed in the 1990s that demonstrated a 65 percent increase in the anastomotic cross-sectional area [135] and reduced morbidity for patients undergoing a cervical esophagogastric anastomosis [137]. In a review of 274 patients, those undergoing a hybrid anastomosis (modified Collard technique, n = 86 patients) had fewer cervical wound infections compared with patients undergoing a hand-sewn anastomosis (8 versus 29 percent) [137]. Patients undergoing a hybrid anastomosis had a statistically similar leak rate but required fewer anastomotic dilatations (4 versus 11 percent, mean 2.4 versus 4.1 per patient, respectively).
  37. Orthotopic placement of the neoesophagus in the posterior mediastinum is generally preferred.
  38. The role of a pyloroplasty or pyloromyotomy to reduce the risk of gastric outlet obstruction following a gastric pull-up procedure has been challenged by prospective studies and randomized trials, including:
  39. Minimal liquid diet for approximately 2 weeks to allow the conduit to remain decompressed and straight in the mediastinum. The American College of Chest Physicians Guidelines on the Prevention of Venous Thromboembolism [150] classified esophagectomy as a high-risk procedure and thus recommend postoperative thromboprophylaxis with low-molecular-weight heparin, unfractionated subcutaneous heparin three times daily, or fondaparinux. Conversely, some would classify esophagectomy as high risk for bleeding, especially in the setting of blunt mediastinal dissection, and thus argue for less aggressive prophylaxis. Further complicating the matter is the frequent use of neuraxial anesthesia, which further limits the use of perioperative anticoagulants for thromboprophylaxis [151]. Unfortunately, a paucity of data exists to help clarify these issues, and, therefore, clinical practice varies. We use subcutaneous heparin and pneumatic boots beginning in the operating room and continuing until postoperative day 7 or until they are ambulatory.
  40. Postoperative pulmonary complications are the most significant factor contributing to death following esophageal resection and reconstruction. In a retrospective review of 379 patients, the incidence of death for patients who developed pneumonia was significantly higher compared with those who did not (20 versus 3 percent) [21]. Increasing age was the only other variable independently associated with postoperative mortality. Anastomotic complications were once associated with a 50 percent mortality rate, but with aggressive management, including immediate reoperation for uncontained leaks, or in some cases stent placement, mortality resulting from leak has declined [28]. (See 'Pulmonary' below and 'Anastomotic leak' below.)
  41. Clearly, this single-center study requires further evaluation but raises concern regarding potential long-term d etrimental effects of routine thoracic duct ligation. Short course of conservative management. Early surgical intervention (within 14 days from diagnosis) is favored by many surgeons because of the high mortality rate associated with the resultant immunologic and nutritional depletion in an already compromised patient population [80,81].
  42. An esophagectomy can exert temporary [156-163] and long-term detrimental impacts on health-related quality-of-life (HR-QOL)
  43. Surgeon experience, dedicated intensive care teams, nursing skill, respiratory therapy, resource allocation, multidisciplinary team management, and availability of advanced diagnostic and therapeutic equipment are examples of variables that are likely enhanced at high-volume centers
