Introduction: Severe acute pancreatitis, according to Atlanta classification, is a heterogeneous group of patients with different outcomes. The patients with local complications and without organ failure have better outcome. This study has been conducted to determine the proportion of moderately severe acute pancreatitis and validate this subgroup in our population of patients.Methods: A total of 172 patients with the diagnosis of acute pancreatitis were categorized into three groups according to presence or absence of local complications and organ failure as mild acute pancreatitis, moderately severe acute pancreatitis and severe acute pancreatitis and were compared in terms of need for intensive care unit care, length of ICU stay, need for intervention, length of hospital stay and mortality.Results: Fifty seven (33%) were categorized as moderately severe acute pancreatitis. Need for ICU care (19.3% vs 100%, p < 0.001), length of ICU stay (1 vs 9.8 days, p < 0.001), length of hospital stay (8.3±3.7 vs 16.6±8.1 days, p < 0.001) and mortality (0% vs 33.3%, p < 0.001) between moderately severe acute pancreatitis and severe acute pancreatitis was significantly different. Moreover, mild acute pancreatitis and moderately severe acute pancreatitis had no mortality.Conclusions: This study showed that moderately severe acute pancreatitis exists as a separate group different from mild acute pancreatitis and severe acute pancreatitis with no mortality as in mild acute pancreatitis. Keywords: moderately severe acute pancreatitis; Atlanta classification; outcome.

INTRODUCTION:Irritable bowel syndrome (IBS) is a common public health problem. The condition is characterized by a scarcity of biological markers; thus, diagnostic definitions and classifications have relied to a large extent on symptoms, gastrointestinal manifestations of patients. While thyroid disorder should be considered in the differential diagnosis of patients with IBS symptoms, it is not clear if thyroid disturbances amongst patients with IBS are high enough to warrant routine screening. This study was done to see the prevalence of thyroid dysfunction in IBS patients and hence its significance

Introduction:A casual relation has been thought to exist between Helicobacter pylori infection and gastric cancer. The present study was carried out to find correlation between H. pylori and gastric carcinogenesis. Methods: A case control study was performed in the department of endoscopy, Tribhuvan University Teaching Hospital, between January 2008 and February 2009. All patients having carcinoma stomach on endoscopic evaluation later confirmed by histopathological examination were included. Total 50 healthy individuals, with no positive finding in endoscopy were included in control group. Results: Total 37 cases were analyzed. There were 23 (62.2%) males and 14 (37.8%) females. Majority were above 60 years (46%). Blood group A was commonest group found in patients with carcinoma stomach. Distal part, antrum, 20 (54%) was commonest location of tumor and Borrmann type three was commonest endoscopic type of tumor presentation. Majority of patients received triple therapy and H. pylori detection was low in those treated with triple therapy. Distal tumors were significantly associated with increased prevalence of H. pylori positivity. Total incidence of H. pylori in cases was 54% (20/37). In 15 (75%) cases, H. pylori could be detected by both ELISA and biopsy method. Incidence of H. pylori in controls was 64% (32/50). There was no statistically significant difference in H. pylori presence in cases and control. Conclusions: Our study couldn’t establish association between H. pylori and gastric cancer. More prospective trials can help find out correlation between combination of risk factors and gastric cancer.  Keywords: helicobacter pylori; gastric cancer; risk factors.

Introduction: As cites, a common entity in practice of gastroenterology is path physiologically divided into high SAAG and low SAAG category, to rapidly classify, formulate a workup plan and expedite the diagnosis. The cause of low SAAG as cites is often due to local peritoneal cause e.g. peritoneal tuberculosis, peritoneal carcinomatosis etc, mandating the need of peritoneoscopy for definitive diagnosis. This study aims to present the peritoneoscopy and peritoneal biopsy result of patients with low SAAG as cites of uncertain etiology. Methods: Peritoneoscopy was prospectively performed in 12 patients with low SAAG as cites of unclear etiology. Patients with low SAAG as cites and willing to give consent for peritoneoscopy were enrolled in the study. Patients underwent laparoscopic peritoneoscopy under general anesthesia and appropriate biopsies were taken during the procedure for histopathological analysis. Results: Of the twelve patients with low SAAG enrolled in the study, 3 (25%) were male and 75% (9) were female. The success rate of the procedure was 100% and there was no procedure related complications. Specific findings were seen in all patients undergoing peritoneoscopy. Of the twelve patients, 9 (75%) patients has metastatic deposits in the peritoneum, 3 (25%) had benign etiology, 2/3rd (2) of whom had granulomatous deposits suggestive of tuberculosis and 1/3rd (1) had extensive dense adhesions and peritoneal fibrosis. Primary focus was revealed (ovary) in only 1 patient undergoing peritoneoscopy. Conclusion: Peritoneoscopy with simultaneous biopsy is safe, efficient and accurate diagnostic method due to its high diagnostic capacity and low complication rate in selected patients who have low SAAG as cites of uncertain etiology.
