Introduction: Anal fissure is an ischemic ulcer caused by combination of spasm of internal anal sphincter and poor blood supply to the posterior midline of anal canal. This study aimed to assess the efficacy of Glyceryl Trinitrate and Nifedipine in the treatment of chronic anal fissure. Methods: Ninety patients with symptomatic anal fissure in Kathmandu Medical College Teaching Hospital are allocated for study in two groups of 45 each from March 2013 to April 2014. The patients are assigned alternatively to GTN group and Nifedipine group. All patients were assessed every week till 8 weeks in regards to headache, compliance, healing and recurrence. The patients who had complete healing in 8 weeks were further followed up for 6 weeks to detect recurrence. Results: Patients in the two groups were comparable in regard to demographic data (age and sex) as well as clinical factors. Headache was main complaint of patients using GTN in high percentage (16.6%) than complained by patients using topical Nifedipine (6.9%). This factor led to poor compliance with GTN compared with Nifedipine.  Nifedipine showed better healing rate 82.5% compared with GTN 60%. Recurrence was comparable among the two groups. Conclusions: Nifedipine ointment showed better results than GTN ointment in chronic anal fissure regarding headache, compliance, healing and recurrence in 6 weeks of follow up period after complete healing of fissure in 8 weeks. Keywords: anal fissure; glyceryl trinitrate; nifedipine.

Background: Laparoscopy surgery trials are small and unconvincing at present and are limited to higher centers. The objective of the study is to determine the clinical features, prevalence of site of hydatid cyst and complications of this modality of this treatment. Methods:A cross sectional study was carried out in all patients with one or two hepatic hydatid cyst who underwent laparoscopic management in KMCTH from January 2013 to March 2015 were included in the study. Aspiration, deroofing and evacuation of the hydatid cyst were done.Results: Twenty six patients underwent laparoscopic management for liver hydatid cysts. Males were seven (65.38%) and females were 9(34.61%).The mean age was 35.5±13.1 years (range 21-55years.) The commonest complaint was pain and discomfort in 13(50%) patients and lump in 6(13.06%) patients. Twenty four (92.3%) patients were successfully treated with laparoscopic approach. Two (7.69%) patients had to be converted to laparotomy because of dense adhesions and bleeding. Mean operation time was 43.6±10.6 minutes. Two (7.69%) patients had port site infection. One (3.84%) patient had bile leak and no recurrence and mortality in our series. Conclusions:Laparoscopic management of liver hydatid cyst was safe and effective in selective group of patients in equipped hospital.

Background: Peptic ulcer disease is one of the most common diseases prevalent in developing country like Nepal and with availability of endoscopy there have been increase in diagnosis and therapeutic use of endoscopy. Objective: The aim of this study is to investigate the prevalence of peptic ulcer disease in patient who came for upper gastrointestinal endoscopy in Kathmandu Medical College Teaching Hospital. Materials and methods:All patients who were referred to department of endoscopy from outpatient department (OPD) and inpatient department with symptoms like dyspepsia, upper GI bleeding were included from August 2004 to August 2008. Results: A total of 2761 patient were evaluated, with mean age group of 40.57 years (range 8-95 years) and with sex distribution of male 1353 (49%) and female 1408 (51%) and racial difference into Aryan 2050 (74.2%) and Mongoloid 771 (25.8%). There were 983 patients (35.60%) with peptic disease which includes erosive gastritis, non erosive gastritis, duodenitis and gastroduodenitis without obvious ulcer. The prevalence of peptic disease with or without ulcer was more common in age group of 20-49 years (n= 764, 27.67 %) with 70 patient with gastric ulcer (2.5%) and 50 patient with duodenal ulcer (1.8%). There was no signi¿ cant racial difference among incidence of peptic ulcer (P value= 0.527). Conclusions: Peptic ulcer disease is a signi¿ cant cause of morbidity in urban population of Nepal with more prevalent of erosive diseases in productive age group (20-49 years). However both male and female have equal incidence of peptic ulcer disease and there was no signi¿ cant racial difference in its incidence.

Introduction: Safe dissection of Calot’s Triangle is important during the performance of laparascopic cholucystectomy. The purpose of the study is to determine the frequency of demonstrable Rouviere’s sulcus in patients with symptomatic gall stones and its role in safe dissection in Calot’s triangle. Methods: This is a prospective descriptive study design done in Department of surgery, Kathmandu Medical College Teaching Hospital from Jan 2013 to Jan 2015. Patients who were posted for laparoscopic cholecystectomy were included. During laparoscopy, Rouviere’s sulcus was noted in the operative note and classified according to following: Type I: Open type was defined as a cleft in which the right hepatic pedicle was visualized and the sulcus was opened throughout its length. Type II: if the sulcus was open only at its lateral end. Type III If the sulcus was open only at its medial end. Type IV: Fused type was defined as one in which the pedicle was not visualized. Results: A total of 200 patients underwent laparoscopic cholecystectomy during period of 2 years. Out of which Rouviere’s sulcus was visualized in 150 patients (75 %).Type I (open type) was commoner in 54%, type II in 12%, Type III in 9% and type IV (fused type) in 25%. Conclusions: Rouviere’s Sulcus is an important extra biliary land mark for safe dissection of Calot’s triangle during laparoscopic cholecystectomy.  Keywords: Rouviere’s Sulcus, laparoscopic cholecystectomy, bile duct injury.
