3. Inspection: accessible painful lump with fluctuation when touched; liquor puris can be
extracted via injector
2.1.4 Anal fissure
Main symptoms: a little defecation with pain and blood; fresh red; sometimes attached
to surface of defecation; blood drop at time; habitual constipation
Inspection: anal fissure in gradeⅠ, skin of anal canal splits completely, forming into
inflammatory ulcer, base of which is clean and trimmed, no complications or with a
light anal sinusitis, inflammation of anal papilla; in gradeⅡ,base of ulcer is hoary, rim
becomes thicker and untrimmed, undetermined texture, elasticity of anal canal
lessened, remaining looseness, complications are sentinel pile, hypertrophy of anal
papilla, anal sinusitis, etc.; in gradeⅢ, state of ulcer appears as in gradeⅡ with
fibrosis, anal stenosis, complications are sentinel pile, hypertrophy of anal papilla and
subcutaneous fistula, etc.
2.2 Intake standard: all those conforming to diagnostic criteria above
2.3 Exclusion standard: hypertension, hepatocirrhosis, patients suffering from
hemorrhagic diseases, severe heart diseases, psychopathy and those in gestation
period suckling period
3. Treatment method
3.1 Hemorrhoid
Complete defecation before operation, local cleaning, take lithotomy or literal
position according to morbid part, routine sterilization, anaesthetize by lidocaine of
1%, press electronic pincers, use tissue forceps to uplift upper part of hemorrhoid, use
electronic pincers to clip its base(excessive inward clip of internal hemorrhoids should
be avoided in case intestinal wall is injured); make sure it is well clipped, step on foot
switch, the device sounds alarm automatically after 3-5 seconds which means
treatment is finished, then take off pincers, cut residual tissues with pencil; for larger
ones, cilp the tissue from different surfaces untill the hemorrhoid nucleus retreat with
anus. 23 cases each time, after treatment, insert a piece of compound indomethacin
suppositories into the anus; use aquae tepida to wash anus after defecation everyday
and insert a piece of compound indomethacin suppositories so as to make defecation
easy and smooth.
3.2 Anal abscess
Preoperation preparations are as hemorrhoid, rutine strelization,local antisepsis, press
eletronic pencil button, step on foot switch, cut morbid part with high frequency
electronic pencers so as to discharge pus, then insert vaseline pledget, apply dressing
to focus, cover and fix its position, clean the anus everytime after defecation.
3.3 Anal fissure: Preoperation preparations are as hemorrhoid, through excision of
external sphincter muscle, rutine sterilization, treat in lithotomy position, local
antisepsis, four fingers away from sphincter, press electronic pencil, step on foot
switch, cut at 12cm in the perianal, at the centre behind anuas, 0.5-1cm or so under
skin, use vessel forceps to pick up sphincter, then cut it off; if incision is 0.5cm,
extrude two sides so as to match them; for bigger ones, bind them up after operation.

Keywords: hemorrhoid; LG2000 anorectal treating device; curative effect
observation
Our department has treated 62 hemorrhoid cases with satisfactory effect through
adopting LG2000 anorectal treating device (Enhancement) manufactured by
Zhengzhou Safute Electronic Equipment Co., Ltd. The treatment process is as follows:
1. Data and method
All of 112 cases are outpatients, divided into treatment group with 62 and control
group with 50. Treatment group: sex-28 males and 34 females; average age-32.5±14.4;
course of disease-1 month to 3 years; 40 internal hemorrhoids of Ⅱor Ⅲ grade, 22
Page 5 of 9

6. thrombotic external hemorrhoids. Control group: sex-21 males and 29 females;
average age-33.3±15.5; course of disease-3 months to 4 years; 37 internal
hemorrhoids of Ⅱor Ⅲ grade, 13 thrombotic external hemorrhoids. It is not
statistically significant in sex and age differences, so cases are comparable(P﹥0.05).
1.1 Treatment method
(1) Treatment group: Treated by electronic pincers and electronic pencil of LG 2000
anorectal treating device (E) in dorsosacral or lateral position, sterilized routinely,
applied sacral or local anaesthesia, consequently anus becomes completely loose and
hemorrhoid nucleus appears entirely. Notice that patients with hypertension,
hepatocirrhosis, hemorrhagic diseases, severe heart diseases, psychic diseases, and
those in sucking period are excluded.
For internal hemorrhoid, use tissue forceps to clip hemorrhoid, uplift it, then adopt
electronic pincers to closely clip its base (make sure it is well clipped), step on foot
switch for 3-5 seconds, the device sounds alarm and cut electricity automatically
when treatment is finished, then remove foot from foot switch, take off pincers, a dry
and hard tissue is formed without carbonization. For thrombotic external hemorrhoid,
first get rid of skin tissues at the thrombus with electronic pencil, and then treat it with
pincers. If hemorrhoid is larger, treat it in the same way for several times with special
attention to reserve Skin Bridge.
(2) Control group: use traditional ligation for internal hemorrhoid and excision for the
external, adopt postoperative anti-infection, and employ sitz bath in PP liquor with
concentration of 1:5000 or routine coptis chinensis ointment after defecation.
2. Consequence
2.1 Standard effect
Healing: hemorrhoid disappear, no uncomfortable feeling, get better, etc. hemorrhoids
dwindle, symptoms lessen
Inefficiency: no apparent improvement of symptoms and signs after treatment
2.2 Curative effect
See table 1 below:
Table1 Curative Effects Constrast between Two Groups in Different Periods
10d 20d 30d
Group n
n(%) n(%) n(%)
Treatment 62 41(66.1) 20(32.2) 1(1.6)
Control 50 19(38.0) 26(52.0) 5(10.0)
As shown in table 1, most in treatment group are cured for about 10 days, while 20
days for the other. Specially, for treatment group, it takes 13±2.3d to completely finish
treatment; control group 19±2.5d, delaying 6d averagely with apparent difference(P﹤
0.01).
2.3 Untoward reactions
4 cases with anal tenesmus and edema, 1 with anal pain, none with hemorrhage in
treatment group; in control group, all with pain and hemorrhage in different degrees, 8
Page 6 of 9

7. with anal tenesmus, 1 with edema; few untoward reactions and complications, no
hemorrhage in former group, but anal edema are comparatively more as contrasted
with the latter.
3. Discussion
When treating with electronic pincers and pencil of LG2000 anorectal treating device
(E), BEIM can intelligently and properly adjust output impedance, water of
hemorrhoid tissues vaporizes instantly, the tissues rapidly become dry and hard
without carbonization and consequently reach best treatment effect with little bleeding,
little suffering, and fine curative effect. It is an ideal anorectal treating device with
multiple functions.
By adopting an inspection system with a computer and a treating system with
electronic pincers, electronic pencil and electronic forceps, LG2000 anorectal treating
device (E) can clearly store pictures, compare them before and after treatment,
support dynamic replay of treating process, and print color graphic case note with
high clarity.
Treatment group is superior to control group in healing period and complication, 6d
compared with traditional surgery. Besides, there is little suffering, little bleeding
during and after surgery, no infection, complications like pain and tenesmus are fewer.
While a few patients, with muscle or skin dermatochalasis and circular hemorrhoids,
show anal edema in different degrees which can be lessened by hot compress and bed
rest. When clipping base of hemorrhoids with electronic pincers, make sure it is well
clipped and sealed, excessive inward clip of internal hemorrhoids should be avoided
in case intestinal wall is injured, resulting in negative consequences.

Observations on Curative Effects of 500 Anorectal Disease
Cases Treated by LG2000 Anorectal Treating Device
Yu Chenghai, Li Peisheng, Zhang Shengli The 460th Hospital of PLA
Du Shaoxian The Second Affiliated Hospital to Zhengzhou University
Due to the introduction of LG2000 anorectal treating device manufactured by
Zhengzhou Safute Electronic Equipment Co., Ltd., curative effects of 100 anorectal
disease cases like internal, external and mixed hemorrhoids, anal fissure,
hyperthrophy of anal papilla, proctopolypus, anal fistula and perianal abscess are
satisfactory from Aug. 2001 to Oct. 2002 . Except for 6 circular hemorrhoid cases
who need hospitalization, the rest are all clinical patients with cure rate reaching 98%,
no serious complications.
Page 7 of 9

8. 1. Clinical data
500cases in the group, 342 males, 158 females; mini age 9, max 74, average 48.6; 130
internal cases, 70 external, 110 mixed, 70 perianal abscess, 80 anal fistula; all are
cured completely one time, except for 10 complicated anal fistular
2. Case selection
Diagnostic criteria: refer to criteria made at National Academic Conference on
Coloproctology in 1975
3. Treatment method
3.1 Anaesthesia
Adopt local prolonged anaesthesia in the perianal, mix 1mm methylthioninium
chloride injecta with 10mm lidocaine of 2% and 10mm sodium chloride of 0.9%, stir
and dilute them, then start infiltration anaesthesia.
3.2 External hemorrhoid
Incise skin of base in the shape of V with high ferquency electronic pencil, clip and
cut it off; for patients with several hemorrhoids, skin bridge should be preserved, no
twin cut on the same planum in case of anal stenosis after operation.
3.3 Internal hemorrhoid
Plan operation according to the number of hemorrhoid and the extent of prolapsus; for
a single one, just clip it; for circular ones, clip vertically and horizontally so as to
avoid postoperative anal stenosis
3.4 Mixed hemorrhoid
For sigle hemorrhoids or those with clear boundary, such as dominant internal
hemorrhois with small external ones, clip the internal and external parts toghther;
conversly, first use high frequency electronic pencil to incise base in the shape of V,
then a little blunt dissection, finally clip and cut off remaining tissues on the two sides
respectively.
3.5 Anal fissure
For patients with sentinel pile, hypertrophy of anal papilla, subcutaeous fistula,
besides routine incision, genucubital position at 9 point and lateral internal sphincter
muscle excision are necessary so that spasm of internal sphincter muscle can be
eliminated, lessen anal stenosis, anal fissure can be cured within one week.
3.6 Prevention of anal abscess after operation
Add Chymotrypsin 1mg to anesthetics, inject it under the incision or spray
BFGF-ESSEX locally; Chymotrypsin can break down fibrin, promote calipary and
lymphatic circulation; BFGF-ESSEX is used for external application, and is named
companion of electronic pencil, hence, effective anal stenosis can be prevented.
4 Evaluation on curative effect
4.1 Standard
Healing: 3-6 months after treatment, hemorrhoid disappears when inspected through
anoscope, no obvious scar, skin of anal canal and rectal mucous membrane are
smooth, no convex or callosity when applied with digital examination, easy and
smooth defecation without blood; efficiency: apparent reduced hemorrhoid, no
propalapsus, lessened defecation with blood; inefficiency: no better sigh for clinical
symptoms. For other anal diseases, healing: focus eliminated, symptoms disappear;
Page 8 of 9

9. apparent efficiency: signs of getting better appear, efficiency: symptoms lessened;
inefficiency: no fine sign.
4.2 Consequence
For all 500 cases, 490 are healed, cure rate is 98%; 10 cases with inefficiency, taking
up 2%.
Discussion:
1. LG2000 anorectal treating device treat hemorrhoid via electronic pincers with
bipolar coagulation & biological electrical impedance anto-measurement (BEIM)
While curing hemorrhoid, high frequency electronic pincers generates heat rapidly to
vaporize water of hemorrhoid tissues instantly. The electronical impedance of
hemorrhoid tissues becomes larger and larger. While electrical impedance of
hemorrhoid tissues matches with output impedance of the device, the tissues become
dry and hard without carbonization, and at the same time the device sounds the alarm
automatically. Its advantages are: parts are heated regularly, tissues become dry and
hard instantly with clear boundary, bleeding is arrested securely and reliably.
2. Easy and convenient operation with multiple functions; wide applicable scope
such as internal, external and mixed hemorrhoids, anal fissure, anal fistula,
hypertrophy of anal papilla, condyloma acuminata, etc.
3. Short treatment: each hemorrhoid needs only 3-5 seconds; local anesthesia is
sufficient, no hospitalization for the most, no affection to normal work and low
expense
4. High cure rate, no complications, low recurrence; cure rate for the treated group is
98%; popular among patients
All in all, we believe that LG2000 anorectal treating device integrates advantages of
electrical ion, RF, microwave and far infrared besides bleeding arresting. It is an ideal
device with multiple functions, short treatment period and rare complication.
