•poor prognosis occurs in 1% of

5. GREY TURNER’S SIGN

6. CULLEN’S
SIGN

7. HEMATOLOGIC
AL
• ABG’s
• Etiology specific investigations
– Serum fasting lipid profile
– Serum Calcium (HypercalcemiaAPHypocalcemia)
– Autoimmune markers
• increased serum levels of IgG4
• serum autoantibodies such as anti-nuclear antibody (ANA),anti-lactoferrin
antibody, anti-carbonic anhydrase II antibody, and rheumatoid factor (RF),
Acid-Base Disturbance Etiology
Metabolic (Lactic)acidosis with high anion gap Hypovolemic shock
Chloride-responsive Hypokalemic Hypochloremic metabolic alkalosis
(Urine chloride < 20 mEq/L)
persistent vomiting
Respiratory acidosis ARDS/resp failure

8. HEMATOLOGIC
AL
• Pancreatic Enzymes’ Assays
– Serum Amylase:
• ONSET: almost immediately
• PEAK: within several hours
Raised Amylase  may not AP
Normal Amylase  may be AP
– 3-4 times upper limit of normal within 24 hrs(90%)
• RETURN to normal depends on severity(3-5 days)
• normal at time of admission in 20% cases
• Compared with lipase, returns more quickly to values below
the upper limit of normal.

9. – Serum Lipase:
• more sensitive/specific than amylase
• Remains elevated longer than amylase(12 days)
Useful if late presentation
Begins to increase 4-8 Hr after onset of symptoms and peaks at 24Hr
Remains elevated for days
Sensitivity 86-100% and Specificity 60- 99%
>3X normal Sensitivity & Specificity is 100%

10. – Urine Amylase
• More sensitive than serum levels
• Remain elevated for several days after serum levels returned to
normal
– Pancreatic-specific amylase (p-amylase)
• Measuring p-amylase instead to total amylase (also
includes salivary amylase) makes diagnosis more
specific(88-93%)

11. HEMATOLOGIC
AL• BASELINES
– CBC:
• Low Hb: prolonged hemetemesis/melena, internal hemorrhage
• Leucocytosis (10,000-30,000/mcL)-infection, non infectious inflammation
• Low platelets-DIC
• Hct –raised in hemoconcentration
– LFT’s:
• raised bilirubin, AST/ALT/LDH, ALP, GGTP- gall stone pancreatitis
– RFT’s:
• raised BUN/cretainine- ATN ARF
– Coagulation profile:
• increased INR-DIC
– BSR:
• > 180 mg/dl-diabetes as a sequelae or cause
– Serum electrolytes:
• Low sodium/potassium: persistent vomiting
• Hypocalcemia- saponification/fat necrosis
– Serum Protein:
• low protein/ albumin

22. GALL STONE PANCREATITIS BY ERCP

23. RENAL HALO
SIGNNORMAL RENAL HALO SIGN
• Renal halo sign
– RATIONALE: peripancreatic inflammatory reaction extension into
pararenal space
– ETIOLOGY: water-density (radiolucent-halo)of inflammation in
anterior pararenal space contrasts with perirenal fat; more common

24. IV CONTRAST ENHANCED COMPUTED
TOMOGRAPHY SCAN• INDICATIONS-DIAGNOSTIC
– Initial assessment of prognosis(CT severityindex)
– Perfusion CT at 3rd day  area of ischemia predict pancreatic
necrosis
• INDICATIONS-THERAPEUTIC:
– CT-guided aspiration of fluid collection/necrotic tissue for gram
staining and culture(sterile vs infected necrosis)
– specimen should be delivered to the laboratory within an hour and
interpreted promptly
– CT-guided pig tail catheter insertion
Seldom needed within first 72 hrs after symptom onset
unless the diagnosis is uncertain, because inflammatory
changes are often not radiological present until this time
*Use of IV contrast may increase risk of complications of pancreatitis and AKI
*Avoided if serum creatinine >1.5 mg/dL
*MRI suitable alternative

pancreatitis might worsen if ERCP is performed
– Provide non-invasive/fast/safe high-quality (Heavily T2–
weighted) imaging for diagnostic and/or severity purposes

30. ENDOSCOPIC
ULTRASONOGRAPHY• INDICATIONS
– Repeated idiopathic acute pancreatitis*
• occult biliary disease- small stones/sludge

• Sphincterotomy/stent and bile duct clearance reduces infective
complications/mortality
NOT INDICATED
• Not needed early in most patients with gallstone pancreatitis who lack
laboratory or clinical evidence of ongoing biliary obstruction
As most of gallstones causing AP readily pass to duodenum and are lost in
stool

• Manometry
– Sphincterof Oddi dysfunction as a cause
• Genetic testing
– may be considered in young(<30 yrs) patients if no cause is evident and a
family history (especially if >1 family member)of pancreatic disease is present

35. RANSON CRITERIA
The Ranson criteria form a clinical prediction rule for predicting the
prognosis and mortality risk of acute pancreatitis.
They were introduced in 1974 by the English-American Pancreatic
Expert and Surgeon, Dr. John Ranson

40. ATLANTA CLASSIFICATION
The Revised Atlanta classification of acute pancreatitis is an
international multidisciplinary classification of the severity of acute
pancreatitis, updating the 1992 Atlanta classification.
It was initially revised in 2012 and then further updated in 2016

45. CT SEVERITY INDEX
The CTSI sums two scores:
1.Balthazar score: grading of pancreatitis (A-E)
2.Grading the extent of pancreatic necrosis
The necrosis scoring system was added to the traditional Balthazar
score in the 1990
Modifications have been made to the CTSI, resulting in the Modified
CTSI (2004)

49. MANAGEMENT OF ACUTE
PANCREATITIS
Dr Avijit Banerjee

51. INITIAL MANAGEMENT
1. Aggressive hydration, defined as 250-500 ml per hour of isotonic
crystalloid solution should be provided to all patients, unless
cardiovascular and / or renal co-morbidites exist. Early aggressive
intravenous hydration is most beneficial the first 12 – 24 h, and may
have little benefit beyond.
2. In a patient with severe volume depletion, manifest as hypotension
and tachycardia, more rapid repletion (bolus) may be needed .
3. Lactated Ringer’s solution may be the preferred isotonic crystalloid
replacement fluid.
4. Fluid requirements should be reassessed at frequent intervals within
6 h of admission and for the next 24 – 48 h. The goal of aggressive
hydration should be to decrease the blood urea nitrogen

52. RATIONALE FOR RAPID HYDRATION
• Despite dozens of randomized trials, no medication has been shown to
be effective in treating AP.
• The rationale for early aggressive hydration in AP arises from
observation of the frequent hypovolemia that occurs from multiple factors:
i. including vomiting,
ii. reduced oral intake,
iii. third spacing of fluids,
iv. increased respiratory losses and
v. diaphoresis.
vi. In addition, researchers hypothesize that a combination of
microangiopathic effects and edema of the inflamed pancreas decreases
blood flow, leading to increased cellular death, necrosis, and ongoing
release of pancreatic enzymes activating numerous cascades.

53. WHY RL?
• Benefits to using the more pH-balanced lactated
Ringer ’ s solution for fluid resuscitation compared
with normal saline. Low pH activates the trypsinogen,
makes the acinar cells more susceptible to injury and
increases the severity of established AP in
experimental studies. Although both are isotonic
crystalloid solutions, normal saline given in large
volumes may lead to the development of a non-anion
gap, hyperchloremic metabolic acidosis.

54. ERCP IN AP
1. Patients with acute pancreatitis and concurrent acute
cholangitis should undergo ERCP within 24 h of admission.
2. ERCP is not needed in most patients with gallstone
pancreatitis who lack laboratory or clinical evidence of ongoing
biliary obstruction.
3. In the absence of cholangitis and / or jaundice, MRCP or
endoscopic ultrasound (EUS) rather than diagnostic ERCP should
be used to screen for choledocholithiasis if highly suspected.
4. Pancreatic duct stents and / or postprocedure rectal
nonsteroidal anti-infl ammatory drug (NSAID) suppositories
should be utilized to prevent severe postERCP pancreatitis in
high-risk patient

55. ROLE OF ANTIBIOTICS IN AP
1. Antibiotics should be given for an extrapancreatic infection,
such as cholangitis, catheter-acquired infections, bacteremia,
urinary tract infections, pneumonia .
2. Routine use of prophylactic antibiotics in patients with severe
acute pancreatitis is not recommended .
3. The use of antibiotics in patients with sterile necrosis to
prevent the development of infected necrosis is not
recommended .
4. Infected necrosis should be considered in patients with
pancreatic or extrapancreatic necrosis who deteriorate or fail to
improve after 7 – 10 days of hospitalization. In these patients,
either – (i) initial CT-guided FNA for Gram stain and culture to
guide use of appropriate antibiotics or – (ii) empiric use of

56. 5. In patients with infected necrosis, antibiotics known to
penetrate pancreatic necrosis, such as carbapenems,
quinolones, and metronidazole, may be useful in delaying or
sometimes totally avoiding intervention, thus decreasing
morbidity and mortality .
6. Routine administration of antifungal agents along with
prophylactic or therapeutic antibiotics is not recommended

57. • The need to place the pancreas at rest until complete
resolution of AP no longer seems imperative.
• Long held assumption that the inflamed pancreas requires
prolonged rest by fasting does not appear to be supported by
clinical and laboratory observations.
• TPN is associated with infections and other line related
complications. Enteral feeding maintains gut mucosal barrier,
prevents disruption and translocation of bacteria that seed
pancreatic necrosis.

58. ROLE OF SURGERY IN AP
• In patients with mild AP, found to have gallstones in the gallbladder, a
cholecystectomy should be performed before discharge to prevent a
recurrence of AP
• In a patient with necrotizing biliary AP, in order to prevent infection,
cholecystectomy is to be deferred until active inflammation subsides and
fluid collections resolve or stabilize .
• The presence of asymptomatic pseudocysts and pancreatic and / or
extrapancreatic necrosis do not warrant intervention, regardless of size,
location, and / or extension .
• In stable patients with infected necrosis, surgical, radiologic, and / or
endoscopic drainage should be delayed preferably for more than 4 weeks to
allow liquefication of the contents and the development of a fibrous wall
around the necrosis .

60. ACUTE NECROTIZING
PANCREATITIS
Conceptually, it is helpful to view the pathophysiology of ANP as
evolving in two clinical
phases:
1>Early (<7 days from the onset of pancreatitis) cytokine-mediated
vasoactive
phase where deaths are related to progressive organ dysfunction and
hypoperfusion;
2>Late (>14 days from the onset of pancreatitis) infection-mediated
septic phase, commonly attributed to secondary bacterial infection
(e.g., infected pancreatic necrosis) leading to persistent multiple
organ system failure

61. MANAGEMENT
1>Adequate, early (within 24 h of diagnosis) fluid resuscitation may
influence the clinical course of patients with AP by reducing the
systemic inflammatory response and development of organ failure
2>Improved supportive care (enteral nutrition, prophylactic
antibiotics),avoiding unnecessary or ill-timed surgical intervention
(CT-guided fine-needle aspiration [FNA], delayed operative
intervention), and targeted, minimally invasive necrosectomy for
infected necrosis using a step-up approach

62. NUTRITIONAL SUPPORT
1>The concept that limitation of enteral feeding is necessary in ANP
to avoid further stimulation of pancreatic exocrine secretion is
outdated
2>Enteral nutrition, when tolerated, is cost effective, decreases
catheter-related infectious complications, improves blood glucose
control and intestinal mucosal integrity
3> Unfortunately, not all patients tolerate enteral feeding, particularly
early in the course of their disease
4>Total parenteral nutrition providing adequate calories and protein
remains useful.

63. PROPHYLACTIC ANTIBIOTICS
<>Secondary infection in pancreatic necrosis is thought to occur
through
1> Translocation of intestinal bacteria (aerobic gram-negative rods,
Enterococcus, and anaerobes) or
2> Through seeding caused by transient bacteremias related to
invasive arterial monitoring lines and venous access sites (gram-
positive cocci)
<>Current policy is to give antibiotic “on demand” to cover possible
sources of infection for specific clinical indications in critically ill
patients until culture results are available to guide further therapy

64. TIMING OF SURGICAL
INTERVENTION
The presence of infection in pancreatic necrosis is confirmed by
either:
(1) radiographic evidence of extra-luminal gas located in the area of
necrosis as seen on cross-sectional imaging
(2) CT-guided percutaneous FNA showing organisms on gram stain
or culture
Operative necrosectomy is best utilized after the third week of a
patient’s clinical course to allow time for the resolution of early
cytokine-mediated vasoactive disease phase, as well as the structural
demarcation between live and dead tissue in the retroperitoneum
percutaneous
CT-guided catheter drainage (PCD) can be an extremely effective
treatment modality BEFORE 3 WEEKS of proven infected APN.

67. METHODS OF NECROSECTOMY

69. POST NECROSECTOMY
COMPLICATIONS
1> Residual retroperitoneal or intraperitoneal fluid collection
2> Postoperative bleeding can be categorized as either early (<24
h)<due to colonic or peripancreatic artery bleed> or late (>24 h) in
the postoperative period< due to pseudo aneurysm>
Common sites of pseudoaneurysm formation in necrotizing
pancreatitis include the splenic, gastroduodenal,
pancreaticoduodenal, and dorsal pancreatic arteries
3>Pancreatic fistulas
4>Postoperative incisional hernias

70. LOCAL COMPLICATIONS OF ACUTE
PANCREATITIS Dr Bulli Boyidi

71. LOCAL COMPLICATIONS OF ACUTE
PANCREATITIS- Pancreatic Fluid Collections
* Acute Peripancreatic Fluid Collection , Acute Necrotic Collection
* Pseudocyst and Walled off Pancreatic Necrosis
- Pancreatic Ascites
- Portal, Splenic Vein Thrombosis
- Pseudoaneurysm

72. PANCREATIC FLUID COLLECTIONS
Revised ATLANTA CRITERIA
- Pancreatic fluid collections are classified as
Acute (< 4 weeks after the episode of pancreatitis )
Chronic (> 4 weeks after the episode of pancreatitis )
- The acute and chronic collections are further subdivided based on the
presence of necrosis within the collections

73. PANCREATIC FLUID COLLECTIONS
Revised ATLANTA Criteria
- Acute collections are divided into
Acute Peripancreatic Fluid Collections (APFC)
Acute Necrotic Collections (ANC)
- Chronic fluid collections are divided into
Pseudocysts
Walled-Off Pancreatic Necrosis (WOPN)

74. PANCREATIC FLUID COLLECTIONS
- Fluid collections associated with Interstitial oedematous pancreatitis (i.e. minimal or
no necrosis)
Acute peripancreatic fluid collections (APFC)
Pseudocysts
- Fluid collections associated with Necrotising pancreatitis
Acute necrotic collections (ANCs):
Walled-off (pancreatic) necrosis ( WOPN):

76. ACUTE PERIPANCREATIC FLUID COLLECTIONS
(APFC)- Amylase rich collections, adjacent to the pancreas , lack a well defined wall
- Seen in Interstitial pancreatitis
- Majority remain sterile
- The usual locations are
Lesser sac
Anterior and posterior pararenal space of the retroperitoneum
Transverse mesocolon
Small bowel mesentery
- Usually resolve with conservative management in 2-4 weeks

77. MANAGEMENT OF APFC
- Majority of them resolve with conservative management
- Intervention is necessary in case of a large collection causing symptoms or
pressure effects
USG guided / CT guided PERCUTANEOUS ASPIRATION
EUS guided Transgastric Drainage
- An APFC that does not resolve can evolve into a PSEUDOCYST

78. ACUTE NECROTIC COLLECTIONS (ANC)
- Pancreatic necrosis refers to diffuse or focal area of non-viable parenchyma
that is typically associated with peripancreatic fat necrosis
- Occurs in Necrotising pancreatitis
- It involves both the pancreas and peripancreatic tissues
- Lacks a well defined wall

79. ACUTE NECROTIC COLLECTION -
MANAGEMENT- Sterile pancreatic necrosis should not be drained or interfered with
- If the patient shows signs of sepsis and peripancreatic fluid is infected ~USG
or more appropriately CT Guided percutaneous aspiration is performed
~ If the aspirate is purulent
. Percutaneous drainage of the infected fluid is done with the possible
widest bore tube drain
. Microbiological assessment of the aspirate and appropriate antibiotic
therapy according to the sensitivity report

80. ACUTE NECROTIC COLLECTION -
MANAGEMENT- If sepsis worsens ,Pancreatic Necrosectomy should be considered
- Pancreatic Necrosectomy
~ Open Surgical approach - challenging operation with high morbidity and
mortality
~ Laparoscopic Approach - Minimally invasive via Trans Peritoneal or
retroperitoneal approach

81. - Once the open surgical necrosectomy has been performed the options are
Closed Continuous Lavage ( Beger ): Tube drains are left in and the raw
areas are flushed
Lavage is carried out through several double and single lumen catheters in
lesser sac
1 litre of Saline is infused through and then drained over a period of hours
The process is repeated

83. - Closed Drainage : The incision is closed but the cavity packed with gauge
filled penrose drains and closed suction drains
The penrose drains are brought out through the flank and slowly pulled out
and removed after 7 days

84. - Open Packing : The incision is left open and the cavity is packed with the
intention of returning to the operation room at regular intervals and
repacking until there is clean granulating cavity
- Closure and Relaparotomy : The incision is closed with drains with the
intention of performing a series of planned laparotomies every 48-72 hours
until the raw area granulates

85. PANCREATIC NECROSECTOMY
- In recent years there has been a shift in paradigm from Open Surgical
Necrosectomy to Endoscopic or Percutaneous procedures
- Surgery is now reserved for cases in which endoscopic or percutaneous
procedures are not feasible
. Infection of the pancreatic bed before a well formed, walled-off collection
is formed
. Abdominal compartment syndrome

86. PANCREATIC NECROSECTOMY
EUS Guided Pancreatic Necrosectomy
- Standard treatment in specialized centres
- Under EUS guidance a cystogastrostomy is done
Minimally invasive Alternatives
- Percutaneous drainage followed by percutaneous or sinus tract endoscopy
with necrosectomy
- Retroperitoneal Laparoscopic necrosectomy via percutaneous access without
entering into the abdominal cavity

87. PSEUDOCYSTS
- Peripancreatic fluid collection containing high concentration of pancreatic
enzymes within a defined fibrous wall and lacking an epithelial lining
- Usually arises from APFC and matures after four weeks or more
- Usually single,occasionally multiple
- More than half communicate with the Main Pancreatic duct

88. PANCREATIC PSEUDOCYST -
MANAGEMENT- Pseudocysts resolve spontaneously in most instances
- Less likely to resolve Thick walled
Large(> 6 cm in diameter)
Lasting for > 12 weeks
Arisen in the context of Chronic pancreatitis
- The therapeutic intervention : Pseudocyst causing symptoms
Complications develop
Neoplasm is suspected

89. MANAGEMENT OF PANCREATIC
PSEUDOCYST- The possible approaches are
Percutaneous
Endoscopic
Open Surgical

90. PERCUTANEOUS DRAINAGE OF
PANCREATIC PSEUDOCYST- Usually done under radiological guidance
- Carries high likelihood of recurrence
- Contraindications - Suspected Neoplasm
Communication with the main PD
- Complications - Infection
Pancreaticocutaneous fistula

91. PANCREATIC PSEUDOCYST -
MANAGEMENT
- Endoscopic Transmural Drainage
Conventional Transmural Endoscopic drainage
. identifying the bulge of Pseudocyst on the gastric wall and creating a
fistulous tract between pseudocyst cavity and gastric lumen and placing one
or more PLASTIC STENT to allow continuous drainage
EUS Guided Transmural Drainage
. particularly useful in pseudocysts without bulge on the gastric wall
. ability to identify vascular structures between cyst and gastric lumen

92. PANCREATIC PSEUDOCYST -
MANAGEMENTEndoscopic Transmural Drainage
- Plastic stents : Multiple, long procedure times, stent occlusion
- Fully Covered Self Expanding Metal Stents (FCSEMS)
Single , shorter procedure times
With/without anti migratory fins
- Novel Lumen Apposing Metal Stents (LAMS) - Less risks of stent migration

93. OPEN SURGICAL DRAINAGE
- The open surgical drainage depending on the location of the pseudocyst
Cystogastrostomy
CystoJejunostomy

94. PANCREATIC PSEUDOCYST -
MANAGEMENT
- Pseudocyst communicating with the main Pancreatic duct
ERCP and placement of a Pancreatic stent across the ampulla

95. WALLED-OFF PANCREATIC NECROSIS (WOPN)
- It is a PFC that contains solid necrotic debris that contains a well defined
capsule with or without fluid component
- Usually develops after necrotising pancreatitis
- Small percentage may resolve spontaneously
- Majority require Surgical Intervention

96. WALLED-OFF PANCREATIC NECROSIS -
MANAGEMENT- Management includes
* Percutaneous Drainage
* Direct Endoscopic Necrosectomy(DEN) - endoscope is passed through the
fistulous tract , mechanical cleaning
* Fully Covered SEMS (limited value)- do not allow the passage of endoscope
* Lumen Apposing Metal Stents - allow the passage of endoscope

97. PANCREATIC ASCITES
- Pancreatic ascites is a chronic, generalised, peritoneal, enzyme rich effusion
usually associated with pancreatic bed disruption
- Paracentesis : Turbid fluid with high Amylase level
- Management : Wide bore drains placed under radiological guidance
Parenteral feeding
Octreotide

98. HAEMORRHAGE
- Bleeding may occur into the gut , into the retroperitoneum, peritoneal cavity
- Possible causes include : Bleeding into the pseudocyst cavity
Diffuse bleeding from a large raw surface
Pseudoaneurysm
False aneurysm of a major peripancreatic vessel
- Diagnosis - CT/ MR Angiography
- Management - Embolisation or Surgery

99. PORTAL OR SPLENIC VEIN THROMBOSIS
- Often develop silently and are identified on a CT Scan
- A marked rise in Platelet count should raise the suspicion
- Management ;
In the context of Acute pancreatitis is conservative
Patient should be screened for pro coagulant tendencies
Varices - Endoscopic banding/injection, Beta- blockade
Thrombocytosis - May mandate Aspirin
Systemic Anticoagulation
