A Rare Case of Endoscopic Removal of 63 Coins From the Stomach of an Adult.

The paper focuses on the use of endoscopy in the extraction of 63 coins from the stomach of an adult psychiatric patient. So far, most such cases were dealt with by traditional surgery, and endoscopy was used for the removal of a few coins only. The present work emphasizes that endoscopy is a better option than surgical intervention as it is faster and has a shorter recovery time, lower risk of infection, and lower cost.

Nutrition in Chronic Liver Disease: Consensus Statement of the Indian National Association for Study of the Liver.

Malnutrition and sarcopenia are common in patients with chronic liver disease and are associated with increased risk of decompensation, infections, wait-list mortality and poorer outcomes after liver transplantation. Assessment of nutritional status and management of malnutrition are therefore essential to improve outcomes in patients with chronic liver disease. This consensus statement of the Indian National Association for Study of the Liver provides a comprehensive review of nutrition in chronic liver disease and gives recommendations for nutritional screening and treatment in specific clinical scenarios of malnutrition in cirrhosis in adults as well as children with chronic liver disease and metabolic disorders.

Colitis and Crohn's Foundation (India) consensus statements on use of 5-aminosalicylic acid in inflammatory bowel disease.

Despite several recent advances in therapy in inflammatory bowel disease (IBD), 5-aminosalicylic acid (5-ASA) therapy has retained its place especially in ulcerative colitis. This consensus on 5-ASA is obtained through a modified Delphi process, and includes guiding statements and recommendations based on literature evidence (randomized trials, and observational studies), clinical practice, and expert opinion on use of 5-ASA in IBD by Indian gastroenterologists. The aim is to aid practitioners in selecting appropriate treatment strategies and facilitate optimal use of 5-ASA in patients with IBD.

Indian consensus on gastroesophageal reflux disease in adults: A position statement of the Indian Society of Gastroenterology.

The Indian Society of Gastroenterology developed this evidence-based practice guideline for management of gastroesophageal reflux disease (GERD) in adults. A modified Delphi process was used to develop this consensus containing 58 statements, which were generated by electronic voting iteration as well as face-to-face meeting and review of the supporting literature primarily from India. These statements include 10 on epidemiology, 8 on clinical presentation, 10 on investigations, 23 on treatment (including medical, endoscopic, and surgical modalities), and 7 on complications of GERD. When the proportion of those who voted either to accept completely or with minor reservation was 80% or higher, the statement was regarded as accepted. The prevalence of GERD in India ranges from 7.6% to 30%, being < 10% in most population studies, and higher in cohort studies. The dietary factors associated with GERD include use of spices and non-vegetarian food. Helicobacter pylori is thought to have a negative relation with GERD; H. pylori negative patients have higher grade of symptoms of GERD and esophagitis. Less than 10% of GERD patients in India have erosive esophagitis. In patients with occasional or mild symptoms, antacids and histamine H2 receptor blockers (H2RAs) may be used, and proton pump inhibitors (PPI) should be used in patients with frequent or severe symptoms. Prokinetics have limited proven role in management of GERD.

Indian guidelines on imaging of the small intestine in Crohn's disease: A joint Indian Society of Gastroenterology and Indian Radiology and Imaging Association consensus statement.

The Indian Society of Gastroenterology (ISG) Task Force on Inflammatory Bowel Disease and the Indian Radiological and Imaging Association (IRIA) developed combined ISG-IRIA evidence-based best-practice guidelines for imaging of the small intestine in patients suspected to have or having Crohn's disease. The 29 consensus statements, developed through a modified Delphi process, are intended to serve as reference for teaching, clinical practice, and research.

Acute hepatitis E in India appears to be caused exclusively by genotype 1 hepatitis E virus.

BACKGROUND: Hepatitis E is caused by infection with hepatitis E virus (HEV), which has four well-known genotypes. Genotypes 1 and 2 HEV have been reported from human cases in areas where the disease is highly endemic. By contrast, genotypes 3 and 4 HEV, which primarily infect several animal species worldwide, have been reported mainly from sporadic human cases in non-endemic areas such as Japan and high-income countries of Europe and North America. To determine whether genotype 3/4 HEV cause sporadic disease in India, a disease-endemic area, we determined HEV genotype in a group of patients with such disease. METHODS: A part of the HEV open reading frame (ORF) 1 was amplified and sequenced from sera of 74 patients with sporadic acute viral hepatitis E from four cities in India. The sequences were compared with prototype sequences for various HEV genotypes and subgenotypes and analyzed using phylogenetic tools to determine the genotype of the isolates. For 12 specimens, a part of HEV ORF2 was also similarly analyzed. RESULTS: Partial ORF1 sequences of all the 74 isolates belonged to genotype 1 HEV, with 88.2% to 100% nucleotide identity with the prototype genotype 1 isolates. Partial ORF2 sequences for all the 12 isolates also belonged to genotype 1 HEV. On phylogenetic analysis, 71 isolates clustered with prototype genotype 1a HEV; the remaining three isolates were located between subgenotypes 1a and 1c but were closer to the former. CONCLUSION: Human sporadic acute hepatitis E in India is caused almost exclusively by genotype 1 HEV.

Imaging of the small intestine in Crohn's disease: Joint position statement of the Indian Society of Gastroenterology and Indian Radiological and Imaging Association.

The Indian Society of Gastroenterology (ISG) Task Force on Inflammatory Bowel Disease and the Indian Radiological and Imaging Association (IRIA) developed combined ISG-IRIA evidence-based best-practice guidelines for imaging of the small intestine in patients with suspected or known Crohn's disease. These 29 position statements, developed through a modified Delphi process, are intended to serve as reference for teaching, clinical practice, and research.

Hepatitis B immunization in healthcare workers.

BACKGROUND: Healthcare workers (HCWs) are at high risk for hepatitis B virus (HBV) infection. The aim of the study was to evaluate HBV immunization status and anti-HBs titer among HCWs. METHODS: AntiHBs titer was prospectively examined in all vaccinated of the 464 HCWs enrolled. A comparison was done between two groups who had received vaccination within or beyond 5 years (Group A >5 years, Group B <5 years) and also between those who received a booster dose, Group I (<1 year) and Group II (>1 year). RESULTS: 49.6% HCWs were vaccinated, 46.1% were unvaccinated, and 4.3% were partially vaccinated. Among HCWs, doctors had the highest vaccination rate of 92.5%, followed by medical students (62.4%), nursing staff (41.6%), technical staff (24.2%), administrative staff (12.1%), nursing students (8.5%), and grade IV/laundry staff (0%). Of the vaccinated HCWs, 30% had anti-HBs titer <10 mIU/mL, 10.8% between 10-100 mIU/mL, and 59.2% >100 mIU/mL. Mean anti-HBs titer between groups A and B was 334.8 and 649.2 mIU/mL, respectively (P<0.05); mean anti-HBs titer between groups I and II was 1742.7 and 629.2 mIU, respectively (P<0.002). CONCLUSION: A significant proportion of HCWs is unvaccinated. A fair proportion of fully vaccinated HCWs can have low titers to protect them against HBV infection. Measuring anti-HBs titer, administering a booster dose, and offering general screening for HBs antigen should be made compulsory for HCWs.

Indian Society of Gastroenterology consensus statements on Crohn's disease in India.

In 2012, the Indian Society of Gastroenterology's Task Force on Inflammatory Bowel Diseases undertook an exercise to produce consensus statements on Crohn's disease (CD). This consensus, produced through a modified Delphi process, reflects our current recommendations for the diagnosis and management of CD in India. The consensus statements are intended to serve as a reference point for teaching, clinical practice, and research in India.

Use of narrow band imaging in assessing duodenal villous atrophy.

BACKGROUND AND OBJECTIVE: Narrow band imaging endoscopy with magnification (NBI-ME) has already been established in Barrett's esophagus, stomach, and colonic mucosa, but limited work has been done in the mucosal evaluation of duodenum. A study was done to determine the correlation between NBI and histology in grading villous architecture in varied etiology. METHOD: A prospective observational study comprising 105 subjects with suspected malabsorption. The presence of a diagnosed celiac disease, severe life threatening comorbidity, or pregnancy was considered as exclusion criteria. Standard endoscopy (SE), NBI-ME, multiple duodenal biopsies with histopathological examination were done in all. RESULTS: Fifty-one patients had celiac disease while 54 patients comprised mainly functional dyspepsia, iron deficiency anemia, tropical malabsorption syndrome, and irritable bowel syndrome. Four NBI-ME image subtypes of villous morphology have been proposed (NBI type I/II/III/IV). NBI-ME had 95 % sensitivity, 90.2 % specificity, 91.2 % positive predictive value, and 94.2 % negative predictive value for diagnosing altered villous morphology. Intraobserver kappa agreement coefficient (κ) for NBI-ME was 0.83 while interobserver agreement was 0.89 (95 % CI 0.8-0.97). CONCLUSION: NBI-ME has good performance characteristics and very good kappa intra/interobserver agreement coefficient for varied subtypes of villous morphology. NBI-ME is most useful for obtaining a targeted biopsy which can be missed by conventional white light endoscopy.

Insulin resistance in euglycemic cirrhosis.

BACKGROUND: Insulin resistance (IR) is associated with hepatic fibrosis and cirrhosis, regardless of its etiology but the mechanism of hyperinsulinemia in cirrhosis is still unclear. The current study was designed to assess hyperinsulinemia and pancreatic ß-cell function in euglycemic cirrhosis of varied etiology. METHODS: A cross sectional case control study of 100 subjects. IR was assessed by the Homeostasis Model Assessment (HOMA) and quantitative insulin sensitivity check index in euglycemic cirrhosis of varied etiology and in different stages of cirrhosis. HOMA-ß was calculated for insulin secretion ability of pancreatic ß-cells in different stages of cirrhosis. RESULTS: Overall IR in euglycemic cirrhosis was seen in 68.5%. IR was seen in the order hepatitis C (100%), non-alcoholic fatty liver disease (100%), autoimmune hepatitis (100%), hepatocellular carcinoma (80%), alcoholic liver disease (72%) and hepatitis B (45%). HOMA-IR value was raised in Child Turcotte Pugh (CTP) score >9 (P value 0.0004) and model of end stage liver disease (MELD) score >15 (P value 0.02). HOMA-ß was raised in CTP score >9 (P value 0.02) and MELD score >15 (P value 0.0003). HOMA-ß level among diabetic controls was 27.1±7.7 compared to 154.6±80.7 in euglycemic cases (P value <0.0001). CONCLUSION: IR is common in euglycemic cirrhosis and with advancement of liver disease; there is a compensatory increase in pancreatic ß-cell insulin secretion to overcome the IR. However, over a period of time with fall in ß-cell function development of hepatogenous diabetes may occur.

Cardiac dysfunction in cirrhotic portal hypertension with or without ascites.

BACKGROUND: Alteration of cardiovascular functions in patients with liver cirrhosis has been described and it correlates with severity of hepatic failure. But cardiac functions by conventional 2-dimensional (2-D) echocardiography has limitations. The aim of the study was to evaluate cardiac systolic and diastolic functions in liver cirrhosis patients with or without ascites by tissue Doppler imaging and conventional 2-D- echocardiography. METHODS: A cross sectional case control study of sixty patients. Twenty subjects grouped as healthy controls, pre-ascitic cirrhosis and cirrhosis with ascites were enrolled. Cardiac evaluation was done by both conventional Doppler and tissue Doppler echocardiography. RESULTS: Cirrhosis with portal hypertension is associated with increased heart rate, ejection fraction and mean peak systolic velocity, while mean arterial pressure is decreased. All cardiac chamber dilation occurs and is mostly seen in the left atrium. Ratio of early diastolic annular velocity to peak early diastolic annular wave velocity (E/e') was the most significant marker for diastolic dysfunction. E/e' ratio was 7.76±0.40, 12.55±1.73 and 11.4±1.19 in healthy controls, pre ascitic cirrhosis and ascitic cirrhosis respectively (P<0.0001). Overall Type I and II Left ventricular diastolic dysfunction was present in 70% cirrhotic patient with or without ascites, while there were no cases of Type III (Severe) diastolic dysfunction. CONCLUSION: Left ventricular diastolic dysfunction is commonly associated with advancement of hepatic dysfunction while systolic function is maintained till advanced hepatic failure. Peak early diastolic wave velocity, deceleration time and E/e' ratio for left ventricular diastolic dysfunction are accurately assessed by pulsed tissue Doppler imaging.

Colonic involvement in amebic liver abscess: does site matter?

BACKGROUND: Colonic involvement in amebic liver abscess (ALA) occurs in more than half of the patients. However no studies have found any association between the site of the colonic lesions and location of abscesses in the liver. Thus, the present study was designed to find the correlation between colonic involvement in solitary and multiple ALAs. METHODS: This is a case control study of 80 patients allocated in two groups, the first with solitary (controls) and the second with multiple ALAs (cases). Colonoscopy was performed in all patients enrolled in the study. RESULTS: Solitary ALA was seen in 70% of patients whereas multiple ALAs in 30%. Colonic involvement in the form of erythema, inflammation and ulceration was seen in 77.5% of cases of ALA. 71.4 % cases of solitary ALA had colonic lesions compared to 91.6% cases of multiple ALAs (P=0.02). Most of the patients with multiple ALAs had involvement of the transverse and right colon (75%). Involvement of right colon was present in all patients with colonic involvement. A significant involvement of the right and transverse colon was seen in cases of multiple compared to solitary ALA (P<0.0001). CONCLUSION: Colonic involvement is present in more than two thirds of patients with ALA. When colonic involvement is present, right colon lesion is universally present. Colonic involvement may extend beyond hepatic flexure in patients with multiple amebic ALAs, either involving right hepatic lobe or both lobes.

A young lady with post-partum jaundice and right upper quadrant lump abdomen: an unusual etiology.

Intraductal papillary mucinious neoplasm-biliary type is the biliary counterpart of intraductal papillary mucinious neoplasm-pancreatic type. We report a rare case of intraductal papillary mucinous tumor arising from extrahepatic biliary system. The diagnosis was established on histopathological analysis following endoscopic retrograde cholangiopancreatography-guided biopsy. Isolated papillary adenoma of the bile duct is extremely rare, and in this unusual case the patient was a 22-year-old young lady who had delivered a healthy infant 6 weeks previously.

Comparison of Manning, Rome I, II, and III, and Asian diagnostic criteria: report of the Multicentric Indian Irritable Bowel Syndrome (MIIBS) study.

BACKGROUND: Attempts to diagnose and subtype irritable bowel syndrome (IBS) by symptom-based criteria have limitations, as these are developed in the West and might not be applicable in other populations. OBJECTIVES: This study aimed to compare different criteria for diagnosing and subtyping of IBS in India. METHOD: Manning's and the Rome I, II, and III criteria as well as the Asian criteria were applied to 1,618 patients (from 17 centers in India) with chronic lower gastrointestinal (GI) symptoms with no alarm features and negative investigations. RESULTS: Of 1,618 patients (aged 37.5 [SD 12.6] years; 71.2% male), 1,476 (91.2%), 1,098 (67.9%), 649 (40.1%), 849 (52.5%), and 1,206 (74.5%) fulfilled Manning's, Rome I, II, and III, and the Asian criteria, respectively. The most common reason for not fulfilling the criteria was absence of the following symptoms: "more frequent stools with onset of pain," "loose stool with onset of pain," "relief of pain with passage of stool," "other abdominal discomfort/bloating," and, in a minority, not meeting the duration criterion of 3 months/12 weeks. By stool frequency, constipation-predominant IBS (<3 stools/week) was diagnosed in 319 (19.7%), diarrhea-predominant IBS (>3 stools/day) in 43 (2.7%), and unclassified in 1,256 (77.6%). By Bristol stool form, constipation, diarrhea, and unclassified were diagnosed in 655 (40.5%), 709 (43.8%), and 254 (15.7%) patients, respectively. By their own perception, 462 (28.6%), 541 (33.4%), and 452 (27.9%) patients reported constipation-predominant, diarrhea-predominant, and alternating types, respectively. CONCLUSION: By Manning's and the Asian criteria, a diagnosis of IBS was made frequently among Indian patients with chronic functional lower GI symptoms with no alarm features; the Rome II criteria gave the lowest yield. By the stool frequency criteria, a majority of patients had unclassified pattern, unlike by the stool form and patients' perception of their symptoms.

Indian Society of Gastroenterology consensus on ulcerative colitis.

In 2010, the Indian Society of Gastroenterology's Task Force on Inflammatory Bowel Diseases undertook an exercise to produce consensus statements on ulcerative colitis. This consensus, produced through a modified Delphi process, reflects our current understanding of the definition, diagnostic work up, treatment and complications of ulcerative colitis. The consensus statements are intended to serve as a reference point for teaching, clinical practice, and research in India.

Survey of inflammatory bowel diseases in India.

INTRODUCTION: Inflammatory bowel disease (IBD), both ulcerative colitis (UC) and Crohn's disease (CD), once thought to be uncommon, is now seen commonly in India. The Indian Society of Gastroenterology (ISG) Task Force on IBD decided to collate data on the clinical spectrum of IBD currently prevailing in India. METHODS: An open call to members of ISG was given through publication of a proforma questionnaire in the Indian Journal of Gastroenterology and the web portal of ISG. The proforma contained questions related with demographic features, family history, risk factors, clinical manifestations and characteristics, course of disease, and pattern of treatment of IBD. RESULTS: Of 1,255 filled questionnaires received, 96 were rejected and 1,159 (92.3 %) were analyzed. This comprised data on 745 (64.3 %) patients with UC, 409 (35.3 %) with CD, and 5 with indeterminate colitis. The median duration of illness was longer in patients with CD (48 months) compared to those with UC (24 months) (p = 0.002). More than one half of patients (UC 51.6 %, CD 56.9 %) had one or more extraintestinal symptoms. A definite family history of IBD was present in 2.9 % (UC 2.3 % and CD 4.6 %; p = 0.12). The extent of disease in UC was pancolitis 42.8 %, left-sided colitis 38.8 %, and proctitis alone in 18.3 %. The extent of disease involvement in CD was both small and large intestine in 39.6 %, colon alone in 31.4 % and small intestine alone in 28.9 %. Stricturing and fistulizing disease were noted in 18.8 % and 4.4 % of patients with CD respectively. Chronic continuous and intermittent disease course were present in 35.5 % and 47.2 % of UC patients respectively, and in 23.1 % and 68.8 % of CD patients. Four percent of patients with UC had undergone colectomy, while 15.2 % of patients with CD underwent surgical intervention. CONCLUSIONS: The present survey provides a reasonable picture of the demographic features and clinical manifestations of Indian patients with IBD, their risk factors, course of disease, and the treatment given to them.

Epidemiology and symptom profile of gastroesophageal reflux in the Indian population: report of the Indian Society of Gastroenterology Task Force.

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.

Clinical and laboratory differentiation of cirrhosis and extrahepatic portal venous obstruction in children.

BACKGROUND AND AIM: Differentiation between cirrhosis and extrahepatic portal venous obstruction (EHPVO) in children presenting with features of portal hypertension is important for cost-effective management and proper resource utilization. We undertook this study to differentiate clinical and laboratory features between these two groups of patients. METHODS: Clinical features and laboratory parameters at presentation of children with portal hypertension and cirrhosis of the liver were analyzed. The variables analyzed were age at presentation, duration of symptoms, incidence and frequency of upper gastrointestinal (GI) bleeding, encephalopathy, jaundice, ascites, splenomegaly, and presence of dilated abdominal veins. The laboratory parameters studied were hemoglobin, prothrombin time, serum bilirubin, albumin, aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase. Two groups were compared using appropriate statistical methods; and the differentiating features were analyzed using logistic regression analysis. RESULTS: Of the total of 120 cases, cirrhosis was diagnosed in 28.3% and EHPVO in 71.6%. Children with EHPVO, in comparison to cirrhosis, had significantly higher frequency of upper GI bleeding (61.6%vs 14.7%), increased number of previous bleeding episodes (2.7 +/- 0.5 vs 1.2 +/- 0.4), longer duration of symptoms (25.7 +/- 4.6 vs 12.3 +/- 3 months) and a lower frequency of jaundice (2%vs 76.4%). Low hemoglobin (6.4 +/- 2.7 g/dL) and preserved liver functions characterized by normal bilirubin, albumin levels and prothrombin time were observed in EHPVO cases. Cirrhosis patients had higher hemoglobin (8.8 +/- 2.8 g/dL) and abnormal liver function tests. CONCLUSION: Presence of UGI bleeding and the absence of jaundice are 97.5% accurate in predicting diagnosis of EHPVO.
