Introduction: Irritable bowel syndrome occurs as recurrent abdominal pain that is related to defecation and associated with change in frequency and/or form of stool. Few Patients with IBS may have organic lesions detectable at colonoscopy. Methods: A cross sectional study was carried out in 140 consecutive patients of IBS fulfilling the ROME IV criteria. The study was conducted in Gastroenterology unit, Department of Medicine, Bir hospital, Kathmandu from July 2016 to September 2017. All patients underwent full colonoscopy along with biopsy from sigmoid colon and any visibly abnormal areas. Results: The average age of patients was 37.5 years with 76 (52.8%) males. Forty-two (30%) had IBS-D, 36 (26%) had IBS-C, 31 (22%) had IBS-M and 31 (22%) had IBS-U. Dyspepsia was seen in 16 (11.4%) and fear of TB/Malignancy/IBD was seen in 27 (19.2%). Organic lesions were seen in 39 (27.85%) patients. Nonspecific colitis was seen in 10 (7.1%) followed by ileal erosions in 7 (5%), polyps in 8 (5.7%), hemorrhoids in 6 (4.2%) and diverticula in 3 (2.1%). Only one (0.71%) patient had microscopic colitis and one (0.71%) had malignant lesion seen at histopathological examination. Females with IBS-D had more organic findings than males (P=0.03, RR=4.13, 95% CI=1.21-15.71). Conclusions: The prevalence of organic lesions in patients with IBS fulfilling ROME IV criteria is 27%. Dyspepsia is the most common comorbidity and fear of TB/malignancy/IBD is the most common reason for seeking health care. Females with IBS-D have a higher risk of detecting organic lesions by colonoscopy and histopathology examination.

Background Hepatic encephalopathy (HE) is a common cause of hospital admission in patients with liver cirrhosis (LC). The aims of this study were to evaluate the precipitant factors and analyze the treatment outcomes of HE in LC. Methods All the LC patients admitted between February 2017 and January 2018 for overt HE were analyzed for precipitating factors and treatment outcomes. Treatments were compared among three treatment groups: receiving lactulose, lactulose plus L-ornithine L-aspartate (LOLA), and lactulose plus rifaximin. The primary endpoints were mortality and hospital stay. The chi-square test was used to compare the different treatment outcomes with hospital stay and mortality with significance at p<0.05. Results A total of 132 patients (mean age 49.2 ± 10.2 years; male/female ratio of 103:29) were studied. The most common precipitating factor of HE was infection 65 (49.2%), followed by electrolyte imbalance 54 (41%), constipation 44 (33.33%), and gastrointestinal bleeding 21 (16%) patients. At the time of admission, 29 (22%), 76 (57.5%), 21 (16%), and six (4.5%) patients had grade I, II, III, and IV HE, respectively. The difference in mortality was not statistically significant (p=0.269) in three groups but the hospital stay was shorter among patients in groups B and C than in group A alone (7.36 ± 4.58 and 7 ± 3.69, 9.64 ± 5.28 days, respectively, p=0.015). Conclusions Infection, especially spontaneous bacterial peritonitis, was the commonest precipitating factor of HE. The combination of lactulose either with LOLA or rifaximin is equally effective in improving HE and reducing the duration of hospital stay than lactulose alone.

Introduction: Some studies have suggested that colorectal cancer at a younger age had distinct biological characteristics: different clinical presentations, more advanced stage at time of diagnosis and poorly differentiated carcinoma. The aim of the study is to analyze clinical and histopathological differences between younger (≤40 years of age) and older (>40 years of age) colorectal cancer patients.Methods: A cross-sectional analysis was conducted amongst the colorectal cancer patients who visited Bir Hospital between July 2015 and April 2017. All colonoscopically diagnosed and histopathologically proven cases of colon cancer were included. Chi-square test and independent t – test was performed to analyze the difference between clinical presentations and histopathological findings among two groups of patients and p value of <0.05 was considered as significant.Results: Thirty younger patients and thirty older patients were enrolled without any differences in gender proportion. There were no statistical differences between clinical presentation and histological grade and type in younger and older patients. The younger patients had more complaints of altered bowel habit (p <0.001) while older patients mostly presented with per rectal bleeding (p< 0.008).Conclusions: In this study, colorectal cancer at younger ages showed similar characteristics to those of older patients except altered bowel habit was more common in younger patients while per rectal bleeding was more common in older patients. Although colorectal cancer incidence increases with age, younger patients with altered bowel habits, weight loss, anemia and anorexia should also be given due medical attention and undergo evaluation promptly.  Keywords: carcinoma; colon; per rectal bleeding; younger group. [PubMed]

Introduction: AUGIB is characterized by hematemesis or melena or both. Peptic ulcers and variceal bleed account for majority of cases. Use of proton pump inhibitors in current era is associated with a gradual reduction in burden of peptic ulcer disease. We conducted this study to look into the cause of AUGIB in our community.Methods: We studied 100 patients in one year period who presented to us with hematemesis or melena. The study was conducted in department of Gastroenterology, Bir hospital, Kathmandu. We identified the culprit lesions by upper gastrointestinal endoscopy.Results: The average age of patients with AUGIB was 51.6 years with 59 (59%) males. Duodenal ulcers are most common 29 (29%), followed by varices 23 (23%) and gastric ulcers 14 (14%). More than one lesion was identified in 38 (38%) patients. Patients with variceal bleed were more likely to present with hematemesis alone as compared to those with ulcer bleed (p=0.005). Variceal bleed patients presented earlier to the hospital (p=0.005), had lower MAP at presentation (p=0.0002), had lower hemoglobin level (p=0.0001) and higher serum creatinine level at presentation (p=0.001). Patients with variceal bleed were more likely to have consumed alcohol 20 (86.9%) and patients with ulcer bleed were more likely to be smokers 29 (67.4%) or consume tobacco 14 (32.5%) (p=0.006).Conclusions: Ulcer related bleeding is still the most common cause of AUGIB. Many patients with AUGIB have more than one lesions identified during upper gastrointestinal endoscopy.Keywords:  bleeding; endoscopy; peptic ulcer; upper gastrointestinal;varices. [PubMed]

BackgroundGastro esophageal reflux disease (GERD) is a chronic and recurrent disease, and it varies in regions. However, to date, there are no reports available on clinical features and the risk factors for the asymptomatic reflux esophagitis in Nepalese adults.MethodsData were gathered from 142 erosive patients who had undergone endoscopy at Bir Hospital, Kathmandu. Los Angeles classification was used to grade the severity of the disease. Patients were interviewed to find out the presence of various reflux symptoms.ResultsBased on the Los Angeles classification, the severity of the disease assessed was; grade A 31.8% (31/142), grade B 39.4% (56/142), grade C 33.8% (48/142), and grade D 4.9% (7/142). One hundred and twenty six (88.7%) subjects had reflux symptoms. Prevalence of asymptomatic esophagitis was 16(11.3%). Age was independently linked to asymptomatic esophagitis (P<0.05), and the odd of being asymptomatic appeared lower in younger adults (P<0.05; OR: 0.118; CI: 0.014-.994).ConclusionA low prevalence of asymptomatic reflux esophagitis (RE) was seen. Most subjects experienced mild to moderate RE. Age remained an independent factor associated with reflux esophagitis, and the odds of being asymptomatic was lower in younger age.
