Background: Single balloon enteroscopy (SBE) is a recently developed diagnostic modality to assess small bowel mucosa. The data on learning curve of SBE is scanty. We aimed to assess the learning curve, diagnostic yield and safety of SBE Methods: All patients who underwent SBE at our centre from December 2007 to December 2010 were included retrospectively. The clinical details, enteroscopy findings and procedure related details were obtained for each patient from a prospectively maintained database. The extent of small bowel visualised with increasing number of procedures by a single endoscopist (Endoscopist A) who performed most of the procedures was used to estimate the learning curve using locally weighted regression curve. The diagnostic yield and complications rates of SBE were also estimated. The study was approved by the institute review board and ethics committee. Results: Ninety SBEs were performed in 84 patients (age: 42+15 years, 27.4% females). 57 procedures were performed (32 antegrade and 25 retrograde) by endoscopist A. There was gradual improvement in the extent of small bowel visualised during the first 15 procedures via antegrade route followed by flattening of curve. The retrograde route showed no definite trend towards improvement during the procedures performed. The overall diagnostic yield of SBE was 32.1%. There was no complication except for mild self-limiting abdominal pain in one patient. Conclusions: SBE via antegrade route has a higher success rate and better learning curve than the retrograde route. SBE is a safe procedure and helps in establishing a diagnosis in one-third of the patients examined.

Background and Aim: Gastrointestinal tract (GIT) is one of the major sites of extra-nodal lymphomas constituting 10-15% of all non-Hodgkin's lymphoma cases and about 30-40% of extra-nodal lymphomas. Considerable variation exists in the literature with respect to incidence of the various histological subtypes and sites of involvement. This study was undertaken to ascertain the anatomic distribution, histological subtypes and sites of all GIT lymphomas presenting to a tertiary referral hospital in southern India. Materials and Methods: The histological material of 361 patients over a period of 10 years (2001-2010), with histopathological diagnosis of lymphoma involving the GIT (both primary and secondary), was analyzed retrospectively. All lymphomas were reclassified according to the World Health Organization 2008 classification. Results: These 361 cases include 336 primary and 25 cases of lymphomas, where the involvement was secondary. Primary lymphomas consisted of 267 males (79.64%) and 68 females (20.24%) with a male:female ratio of 3.93:1. The mean age was 45 years (range 3-88). Diffuse large B-cell lymphoma (DLBCL) was the commonest subtype (222 cases; 66.71%), followed by low-grade marginal zone lymphoma of the mucosa associated lymphoid tissue (MALT) type (34 cases; 10.12%) and Burkitt's lymphoma (35 cases; 10.48%). The commonest site was stomach (180 cases; 53.57%), followed by small intestine (79 cases; 23.51%) and large intestine (68 cases; 20.23%), respectively. There were some uncommon types of GIT lymphomas documented during the study. Conclusion: In this largest retrospective single centre study from India, we establish that the pattern of distribution of primary GIT lymphomas (PGLs) in India is similar to the western literature in that the stomach is the commonest site of PGL and DLBCL is the commonest histological subtype. Immunoproliferative small intestinal disease cases were seen in this study, which is uncommon in the west.

Introduction The changing antimicrobial sensitivity pattern of causative organisms poses a therapeutic challenge in treating patients with acute cholangitis. We therefore evaluated the microbial profile and sensitivity pattern to antibiotics in patients with acute bacterial cholangitis. Methods Data of patients above 18 years of age with acute bacterial cholangitis seen between January 2004 and March 2007 were retrospectively analyzed. The study was continued prospectively from April 2007 to December 2008. Data on clinical features, etiological and microbial profile and therapy, and patient outcomes were analyzed. In the prospective group, the antibiotic susceptibility patterns of organisms grown on bile and blood culture were also obtained. Results One hundred and eighty-five patients with acute cholangitis were studied. Choledocholithiasis (62.7%) and malignancy (29.2%) were the main predisposing factors. Bile culture was positive in 88 of 95 patients, and blood culture was positive in 47 of 178 (26.4%) patients. Bile cultures were predominantly polymicrobial (69.5%) in contrast to blood cultures (2.2%). E. coli was the predominant isolate in blood and bile. No growth was seen on anaerobic bile or blood cultures. The prospective group showed high resistance of E. coli to third generation cephalosporins and ciprofloxacin. Conclusions Changing antimicrobial sensitivity patterns requires a revision of empiric antibiotic therapy policy in cholangitis.

Background Gastroesophageal reflux disease (GERD) and its complications are thought to be infrequent in India; there are no data from India on the prevalence of and risk factors for GERD. The Indian Society of Gastroenterology formed a task force aiming to study: (a) the frequency and profile of GERD in India, (b) factors including diet associated with GERD. Methods In this prospective, multi-center (12 centers) study, data were obtained using a questionnaire from 3224 subjects regarding the frequency, severity and duration of heartburn, regurgitation and other symptoms of GERD. Data were also obtained regarding their dietary habits, addictions, and lifestyle, and whether any of these were related or had been altered because of symptoms. Data were analyzed using univariate and multivariate methods. Results Two hundred and forty-five (7.6%) of 3224 subjects had heartburn and/or regurgitation at least once a week. On univariate analysis, older age (OR 1.012; 95% CI 1.003–1.021), consumption of non-vegetarian and fried foods, aerated drinks, tea/coffee were associated with GERD. Frequency of smoking was similar among subjects with or without GERD. Body mass index (BMI) was similar in subjects with and without GERD. On multivariate analysis, consumption of non-vegetarian food was independently associated with GERD symptoms. Overlap with symptoms of irritable bowel syndrome was not uncommon; 21% reported difficulty in passage of stool and 9% had mucus in stools. About 25% of patients had consulted a doctor previously for their gastrointestinal symptoms. Conclusion 7.6% of Indian subjects have significant GERD symptoms. Consumption of non-vegetarian foods was an independent predictor of GERD. BMI was comparable among subjects with or without GERD.

Background: Distinguishing Crohn’s disease (CD) from intestinal tuberculosis (ITB) is clinically challenging but important for prognostication and patient management. Methods: Patients with diagnosis of CD and ITB were prospectively enrolled in the study from January 2006 to October 2007. The patients were followed up for further 15 months to ascertain that the diagnosis had not changed. Clinical, laboratory, serological [IgG anti Saccharomyces cerevisiae antibody (ASCA)], endoscopic and histologic features were compared between the ITB and CD patients. The ASCA titers were estimated in 100 healthy controls. Patients were diagnosed as ASCA positive when their ASCA titers were three standard deviations above mean of controls. Results: Thirty patients with CD (age 33.9 + 15.2 years, 70% males) and thirty with ITB (age 35.1 + 12.2years, 53.3% males) were included in the study. Features commoner in CD were longer duration of symptoms (p<0.001), blood mixed stool (p=0.006), presence of longitudinal ulcers (p=0.005) and skip lesions (p=0.008) on colonoscopy and more number of colonic segments involved (p=0.004). Anorexia was commoner in ITB patients (p=0.008). Positive ASCA was commoner in CD (30%) than ITB (10%) but did not reach statistical significance (p=0.1). Conclusions: A combined evaluation of clinical features, endoscopy, histology and response to treatment is the key to differentiate between CD and ITB.

Background & objectives: Western studies show that up to 65 per cent of patients with Crohn’s disease have low serum 25-hydroxy vitamin D concentrations, and 45 per cent of these patients have metabolic bone disease. No data are available from India or from any country with comparable climatic conditions or ethnicity. We carried out this study to measure the serum 25 (OH) vitamin D levels of Crohn’s disease patients and compare with matched controls and to assess the consequences of low 25 (OH) vitamin D levels on bone and mineral metabolism in these patients. Methods: Adult patients with Crohn’s disease were compared with age and sex matched patients diagnosed to have irritable bowel syndrome. Serum 25 (OH) vitamin D, the effect of disease characteristics, sunlight exposure and milk consumption on 25 (OH) vitamin D level, and the consequences of low 25 (OH) vitamin D level on bone and mineral metabolism were assessed. Results: Thirty four patients with Crohn’s disease (M:F, 24:10, age 39.2 ± 12.9 yr) and 34 controls (M:F, 24:10, age 38.9 ± 13.4 yr) were studied. 25 (OH) vitamin D levels were significantly lower in patients with Crohn’s disease as compared to controls (Crohn’s disease vs controls: 16.3 ± 10.8 vs 22.8 ± 11.9 ng/ml; P<0.05). The severity of disease activity as assessed by the Harvey Bradshaw score correlated negatively (Correlation coefficient -0.484, significance P<0.004), and the duration of sunlight exposure correlated positively (Correlation coefficient 0.327, significance P=0.007) with the serum 25 (OH) vitamin D level. Interpretation & conclusions: Serum 25 (OH) vitamin D levels were significantly lower among patients with Crohn’s disease as compared to age and sex matched controls. Further, 25 (OH) vitamin D levels in patients with Crohn’s disease were lower in those with severe disease activity and less sun exposure. Further studies need to be done to correlate low 25 (OH) vitamin D level with bone density and assess the effect of vitamin D supplementation in these patients.

A 16-year-old boy presented with pericardial effusion, bilateral pleural effusion and mediastinal fluid collection. CT scan of abdomen revealed pancreatic calcification and a fistulous tract from a pseudocyst going along the inferior vena cava wall up to the pericardial cavity. After initial pericardiocentesis and pleurocentesis, lateral pancreatico-jejunostomy with Roux-en-Y loop was performed. The patient is well at 6 months follow up.
