Abstract
BACKGROUND Pre-operative tissue diagnosis for suspected malignant biliary strictures remains challenging. AIM To develop evidence-based consensus statements on endoscopic tissue acquisition for biliary strictures. METHODS The initial draft of statements was prepared following a systematic literature review. A committee of 20 experts from Asia-Pacific region then reviewed, discussed, and modified the statements. Two rounds of independent voting were conducted to reach a final version. Consensus was considered to be achieved when 80% or more of voting members voted "agree completely" or "agree with some reservation." RESULTS Eleven statements achieved consensus. The choice of tissue sampling modalities for biliary strictures depends on the clinical setting, the location of lesion, and availability of expertise. Detailed radiological and endoscopic evaluation is useful to guide the selection of appropriate tissue acquisition technique. Standard intraductal biliary brushing and/or forceps biopsy is the first option when endoscopic biliary drainage is required with an overall (range) sensitivity and specificity of 45% (26%-72%) and 99% (98%-100%), and 48% (15%-100%) and 99% (97%-100%), respectively, in diagnosing malignant biliary strictures. Probe-based confocal laser endomicroscopy and fluorescence in situ hybridisation using 4 fluorescent-labelled probes targeting chromosomes 3, 7, 17 and 9p21 locus may be added to improve the diagnostic yield. Cholangioscopy-guided biopsy and EUS-guided tissue acquisition can be considered after prior negative conventional tissue sampling with an overall (range) sensitivity and specificity of 60% (38%-88%) and 98% (83%-100%), and 80% (46%-100%) and 97% (92%-100%), respectively, in diagnosing malignant biliary strictures. CONCLUSION These consensus statements provide evidence-based recommendations for endoscopic tissue acquisition of biliary strictures.

Abstract
Liver disease due to hepatitis C infection in renal transplant recipients is difficult to treat and often associated with reduced patient survival. A 43-year-old male, a renal allograft recipient, presented at 6 years follow-up with significant weight loss over 3 months. He was detected to have new onset diabetes mellitus together with hepatitis C virus (HCV) infection (genotype 1). His HCV load remained high despite the change of immuno-suppression from tacrolimus to cyclosporine. A decision to treat with a new anti-viral combination of ledipasvir and sofosbuvir for 12 weeks was taken. Within 3 weeks, his raised serum transaminases levels normalized and viral load became undetectable. At the end of 16 weeks, he continues to do well with normal renal function, has sustained remission from hepatitis C infection and resolution of diabetes.

Abstract
Acute pancreatitis is a medical emergency. Alcohol and gallstones are the most common etiologies accounting for 60%-75% cases. Other important causes include postendoscopic retrograde cholangiopancreatography procedure, abdominal trauma, drug toxicity, various infections, autoimmune, ischemia, and hereditary causes. In about 15% of cases the cause remains unknown (idiopathic pancreatitis). Metabolic conditions giving rise to pancreatitis are less common, accounting for 5%-10% cases. The causes include hypertriglyceridemia, hypercalcemia, diabetes mellitus, porphyria, and Wilson's disease. The episodes of pancreatitis tend to be more severe. In cases of metabolic pancreatitis, over and above the standard routine management of pancreatitis, careful management of the underlying metabolic abnormalities is of paramount importance. If not treated properly, it leads to recurrent life-threatening bouts of acute pancreatitis. We hereby review the pathogenesis and management of various causes of metabolic pancreatitis.

Abstract
BACKGROUND AND AIM The purpose of this study was to determine (1) the diagnostic yield for endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) in patients with pancreatic cystic lesions, (2) additional value of EUS-FNA over EUS alone in the diagnosis of pancreatic cysts, and (3) diagnostic sensitivity and specificity of EUS and EUS-FNA in the subset of patients where histopathology of surgical specimens were available. METHODS All patients who underwent EUS examination for the evaluation of pancreatic cystic lesions in six Asian centres were included in the study. RESULTS Of 298 patients with pancreatic cysts who underwent EUS, 132 (44.3 %) underwent FNA. In the entire cohort, pseudocysts and intraductal papillary mucinous neoplasm (IPMN) were the predominant cystic lesions. The cytologic yield of EUS-FNA was 47 %. On univariate analysis, factors associated with higher cytologic yield included vascular involvement on EUS, presence of solid cystic component, and increased number of needle passes during EUS-FNA. On multivariate analysis, presence of solid cystic components and increased number of needle passes during EUS-FNA were associated with higher diagnostic yield of EUS-FNA. For pancreatic cysts with a solid component, the diagnostic yield of EUS-FNA increased significantly from 44 % with one pass to 78 % with more than one pass (p = 0.016). In the absence of a solid component, the diagnostic yield was 29 % with one pass and was not significantly different from the diagnostic yield of 50 % with more than one pass, p = 0.081. CONCLUSION The cytologic yield of EUS-FNA was 47 %. When a solid component was present in the cyst, doing more than one pass during EUS-FNA increased its diagnostic yield.

Abstract
AIM Ampullary tumors are rare. Reports on ampullary tumor staging are heterogeneous and combine both periampullary and ampullary tumors. This study assessed the performance of endoscopic ultrasound (EUS) in the local staging of ampullary tumors only. METHODS Data were collected retrospectively. We included patients with an ampullary tumor who underwent EUS and surgical resection. Tumor (T) and nodal (N) TNM staging for EUS and histopathological (HP) staging were compared. RESULTS From 2009 to 2010, a total of 79 patients with ampullary tumors were identified. Of these, 26 had both EUS and Whipple's surgery and were included (28 did not undergo resection, 13 had palliative surgery only and 12 had resection without EUS). For T staging by HP, there were 2 (7.7 %) T1, 11 (42.3 %) T2, 12 (46.2 %) T3 and 1 (3.8 %) T4 tumors. The accuracy of EUS T staging was 73.1 % with a Kappa value of 0.564 (p < 0.0001). The sensitivity, specificity, positive predictive value (PPV), negative predictive values (NPV) of EUS, respectively were 50.0 %, 91.7 %, 33.3 % and 95.7 % for T1 tumors; 81.8 %, 80.0 %, 75.0 % and 85.7 % for T2; 75.0 %, 92.9 %, 90.0 % and 81.3 % for T3 tumors. For N staging by HP, 17 (65.4 %) were N0 and 9 (34.6 %) N1. The N staging diagnostic accuracy was 80.8 % with a Kappa value of 0.586 (p = 0.003). The sensitivity, specificity, PPV, NPV for N0 disease were 82.4 %, 77.8 %, 87.5 % and 70.0 %, respectively while for N1 they were 77.8 %, 82.4 %, 70.0 % and 87.5 %, respectively. CONCLUSIONS EUS had a moderate strength of agreement with histopathology for both T and N staging, and a high diagnostic accuracy for nodal staging.

Abstract
BACKGROUND AND AIMS Clarification of the position of the European Society of Gastrointestinal Endoscopy (ESGE) regarding the interventional options available for treating patients with chronic pancreatitis. METHODS Systematic literature search to answer explicit key questions with levels of evidence serving to determine recommendation grades. The ESGE funded development of the Guideline. SUMMARY OF SELECTED RECOMMENDATIONS For treating painful uncomplicated chronic pancreatitis, the ESGE recommends extracorporeal shockwave lithotripsy/endoscopic retrograde cholangiopancreatography as the first-line interventional option. The clinical response should be evaluated at 6 - 8 weeks; if it appears unsatisfactory, the patient's case should be discussed again in a multidisciplinary team. Surgical options should be considered, in particular in patients with a predicted poor outcome following endoscopic therapy (Recommendation grade B). For treating chronic pancreatitis associated with radiopaque stones ≥ 5 mm that obstruct the main pancreatic duct, the ESGE recommends extracorporeal shockwave lithotripsy as a first step, combined or not with endoscopic extraction of stone fragments depending on the expertise of the center (Recommendation grade B). For treating chronic pancreatitis associated with a dominant stricture of the main pancreatic duct, the ESGE recommends inserting a single 10-Fr plastic stent, with stent exchange planned within 1 year (Recommendation grade C). In patients with ductal strictures persisting after 12 months of single plastic stenting, the ESGE recommends that available options (e. g., endoscopic placement of multiple pancreatic stents, surgery) be discussed in a multidisciplinary team (Recommendation grade D).For treating uncomplicated chronic pancreatic pseudocysts that are within endoscopic reach, the ESGE recommends endoscopic drainage as a first-line therapy (Recommendation grade A).For treating chronic pancreatitis-related biliary strictures, the choice between endoscopic and surgical therapy should rely on local expertise, patient co-morbidities and expected patient compliance with repeat endoscopic procedures (Recommendation grade D). If endoscopy is elected, the ESGE recommends temporary placement of multiple, side-by-side, plastic biliary stents (Recommendation grade A).

Abstract
AIM Human epidermal growth factor receptor (HER2, also known neu, ERBB2) protein expression in gastric cancer is associated with poor prognosis, aggressive disease and poor response to chemotherapy. Trastuzumab, a monoclonal antibody against HER2, in combination with chemotherapy is currently advocated as a new standard option for patients with HER2-positive advanced gastric and gastroesophageal junction carcinoma. Frequency of HER2 expression in gastric cancer has been reported from different geographic zones with a wide range of 13 % to 91 %. There are no reported data of HER2 protein expression in gastric cancer tissue from India. The purpose of this study was to evaluate the frequency of HER2 expression in gastric cancer. METHODS The frequency of HER2 expression in 52 patients with gastric adenocarcinoma was prospectively evaluated over a six month period at Asian Institute of Gastroenterology from January 2010 to July 2010, using immunohistochemistry (IHC) and fluorescence in situ hybridization (FISH). RESULTS HER2 overexpression was confirmed in 23 of 52 (44.2 %) patients. Two patients had equivocal result by IHC (2+), one of whom was positive on analysis by FISH. There was no difference in HER2 overexpression (positivity) or negativity in relation to age, gender, tumor site, histological subtype, tumor differentiation, serosal involvement or lymph nodal status. HER2 overexpression rates were similar for intestinal type as compared to diffuse histological type (OR 1.84), as also for proximal as compared to distal gastric cancers (OR 0.81). CONCLUSION HER2 overexpression was observed in significant number of advanced gastric adenocarcinoma patients. There was no difference in HER2 overexpression in relation to clinicopathological parameters.

Abstract
Achalasia cardia is a motility disorder of the esophagus characterized by failure of relaxation of the lower esophageal sphincter. Nitrates and calcium channel blockers, pneumatic dilatation, botulinum toxin injection and surgical myotomy have been described in literature as possible management options. We present a patient who presented with achalasia and was co-incidentally diagnosed to have cryptogenic cirrhosis with portal hypertension and had esophageal varices. This clinical combination precluded the use of pneumatic dilatation and surgical myotomy. We injected botulinum toxin into the lower esophageal sphincter using a celiac plexus neurolysis needle under endoscopic ultrasound guidance; the clinical response was good.

Abstract
Endoscopic ultrasound (EUS) and EUS-guided fine-needle aspiration (EUS-FNA) play increasingly prominent roles in the diagnosis and management of pancreatic cysts. The Asian Consortium of Endoscopic Ultrasound was recently formed to conduct collaborative research in this area. This is a review of literature on true pancreatic cysts. Due to the lack of systematic studies, there are no robust data on the true incidence of pancreatic cystic lesions in Asia and any change in over the recent decades. Certain EUS morphological features have been used to predict particular types of pancreatic cysts. Pancreatic cyst fluid viscosity, cytology, pancreatic enzymes, and tumor markers, in particular carcinoembryonic antigen, can aid in the diagnosis of pancreatic cysts. Hemorrhage and infection are the most common complications of EUS-FNA of pancreatic cysts. Pancreatic cysts can either be observed or resected depending on the benign or malignant nature, or malignant potential of the lesions. Guidelines from an international consensus did not require positive cytological findings to be present in their recommendation for resection, which included all mucinous cystic neoplasms, all main-duct intraductal papillary mucinous neoplasms (IPMN), all mixed IPMN, symptomatic side-branch IPMN, and side-branch IPMN larger than 3 cm. In patients with poor surgical risks, EUS-guided cyst ablation of mucinous pancreatic cysts is an alternative. As long-term prospective data on pancreatic cysts are still not available in Asia, management strategies are largely based on risk stratification by surgical risk and malignant potential. Gene expression profiling of pancreatic cyst fluid and confocal laser endomicroscopic examination of pancreatic cysts are novel techniques currently being studied.

Abstract
BACKGROUND Currently available techniques to diagnose indeterminate biliary lesions have many limitations. OBJECTIVE To assess the accuracy of single-operator peroral cholangioscopy by using the SpyGlass system to differentiate malignant from benign disease in patients with indeterminate biliary lesions. DESIGN Prospective, single-arm, single-center study. SETTING Tertiary referral center. PATIENTS Thirty-six patients with indeterminate biliary strictures and filling defects who had inconclusive results on previous biliary ductal tissue sampling. INTERVENTIONS SpyGlass cholangioscopy with cholangioscopically guided intraductal biopsies. MAIN OUTCOME MEASUREMENTS Accuracy of SpyGlass visual impression and SpyBite biopsies for differentiating malignant from benign ductal lesions. RESULTS Thirty-six patients (22 men, mean age 48.3 years [range 27-68 years]) with indeterminate stricture and/or filling defects underwent SpyGlass cholangioscopy. Of the 22 patients with a final diagnosis of malignant lesion, cholangioscopic impression was malignant in 21 patients (95%) and benign in 1 patient (5%). Of the 14 patients with a final diagnosis of benign disease, including the 3 patients with common bile duct stones and no stricture, cholangioscopic impression was malignant in 3 patients (21%) and benign in 11 patients (79%). The overall accuracy of SpyGlass visual impression for differentiating malignant from benign ductal lesions was 89% (32/36). The accuracy of SpyBite biopsies for differentiating malignant from benign ductal lesions that were inconclusive on ERCP-guided brushing or biopsy was 82% (27/33) in an intent-to-treat analysis. LIMITATIONS No randomized comparison with alternative diagnostic modalities for the nature of biliary strictures. CONCLUSIONS SpyGlass cholangioscopy with SpyBite biopsies has a high accuracy with regard to confirming or excluding malignancy in patients with indeterminate biliary lesions.

Abstract
BACKGROUND AND STUDY AIMS Covered self-expanding metal stents (SEMSs) have proven effective for managing malignant bile duct strictures and may reduce risk of tumor ingrowth. A new nitinol partially covered biliary SEMS was prospectively evaluated. PATIENTS AND METHODS 70 patients with inoperable extrahepatic biliary obstructions were enrolled in a prospective multicenter trial, and followed up to 6 months or death, whichever came first. Primary endpoint was adequate palliation defined as absence of recurrent biliary obstruction from partly covered SEMS placement to end of follow-up. RESULTS Mean age of the patients was 69 years and 52 % were men. Pancreatic carcinoma was present in 68 %. One stent was placed in 67 patients, two patients received two, and in one patient a guide wire could not traverse the stricture. In 55 % of patients the SEMS was inserted de novo and in 45 % for exchange with a plastic stent. Technical success was 97 %. At 6 months, 62 % of patients were free of obstructive symptoms; compared with baseline the mean number of symptoms per patient was significantly reduced (3.1 at baseline, 0.6 at 6 months; P < 0.0001) and total bilirubin levels dropped by 73 %. There were four cases of recurrent biliary obstruction, due to stent migration (2), tumor overgrowth (1), and sludge formation (1). Device-related complications included cholecystitis (3), right upper quadrant pain (1), and moderate pancreatitis (1). No tumor ingrowth was reported. CONCLUSIONS This new partially covered nitinol SEMS is easily inserted, and safe and effective in the palliation of biliary obstruction secondary to malignant bile duct strictures.

Abstract
BACKGROUND/AIMS High-resolution manometry (HRM) with pressure topography is used to subtype achalasia cardia, which has therapeutic implications. The aim of this study was to compare the clinical characteristics, manometric variables and treatment outcomes among the achalasia subtypes based on the HRM findings. METHODS The patients who underwent HRM at the Asian Institute of Gastroenterology, Hyderabad between January 2008 and January 2009 were enrolled. The patients with achalasia were categorized into 3 subtypes: type I - achalasia with minimum esophageal pressurization, type II - achalasia with esophageal compression and type III - achalasia with spasm. The clinical and manometric variables and treatment outcomes were compared. RESULTS Eighty-nine out of the 900 patients who underwent HRM were diagnosed as achalasia cardia. Fifty-one patients with a minimum follow-up period of 6 months were included. Types I and II achalasia were diagnosed in 24 patients each and 3 patients were diagnosed as type III achalasia. Dysphagia and regurgitation were the main presenting symptoms in patients with types I and II achalasia. Patients with type III achalasia had high basal lower esophageal sphincter pressure and maximal esophageal pressurization when compared to types I and II. Most patients underwent pneumatic dilatation (type I, 22/24; type II, 20/24; type III, 3/3). Patients with type II had the best response to pneumatic dilatation (18/20, 90.0%) compared to types I (14/22, 63.3%) and III (1/3, 33.3%). CONCLUSIONS The type II achalasia cardia showed the best response to pneumatic dilatation.

Abstract
BACKGROUND AND AIM In spite of recent developments in the field of enteroscopy the small bowel remains the challenging organ to access. The spiral enteroscopy is a novel technique using a special over-tube (Endo-Ease Discovery SB) system for deep intubation of the small bowel. The aim of the present study was to evaluate the efficacy of spiral enteroscopy with an Olympus enteroscope (SIF Q 180) in an Asian subset of patients. METHODS Between January and March 2010, 11 patients underwent spiral enteroscopies. The indication for the procedure was obscure gastrointestinal bleeding in five patients, Crohn's disease in two, malabsorbtion syndrome in two, Peutz-Jeghers syndrome in one and Osler Weber Rendu disease in one patient. RESULTS Eleven patients (five male and six female) mean age 41.6 years (range 21-62 years) underwent spiral enteroscopy. Spiral enteroscopy advancement was successful in all patients. The average depth of insertion was 249 cm (range 120-400 cm) past the ligament of Treitz, and the average time for the procedure was 27.8 min (range 20-32 min). The findings included ulcers (n = 3), polyps (n = 1), arteriovenous malformation (n = 2), ulcer with stricture (n = 1), and lymphangiectasia (n = 1). No major complications were observed. CONCLUSION In conclusion, our initial experience with spiral enteroscopy shows that it is easy to perform, takes less time than balloon assisted enteroscopy and is relatively safe.

Abstract
AIM Large pancreatic ductal calculi and pain are a feature of chronic calcific pancreatitis (CCP) in the tropics. This large single center study evaluates the role of extracorporeal shock wave lithotripsy (ESWL) in fragmentation of large pancreatic stones and relief of pain in patients with CCP. METHODS Patients with CCP presenting with pain and large pancreatic duct (PD) calculi (>5 mm diameter) not amenable to extraction at routine endoscopic retrograde cholangio pancreatography (ERCP) were taken up for ESWL using a 3rd generation lithotripter. Stones in the head and body of pancreas were targeted at ESWL; 5,000 shocks were given per session. The calculi were fragmented to <3 mm size and then cleared by endotherapy. Pancreatic duct stents were deployed when indicated. A total of 1,006 patients underwent ESWL. Complete clearance was achieved in 762 (76%), partial clearance in 173 (17%) and unsuccessful in the rest. More than 962 (90%) of patients needed less than three sessions of ESWL. At 6 months, 711 (84%) of 846 patients who returned for follow up had significant relief of pain with a decrease in analgesic use. Complications were mild and minimal. CONCLUSION ESWL is an effective and safe modality for fragmentation of large PD calculi in patients with CCP.

Abstract
AIM: To evaluate the efficacy of thoracic epidural analgesia for extracorporeal shock wave lithotripsy (ESWL).
METHODS: ESWL is an effective, non-invasive technique for the treatment of difficult pancreatic and large bile duct calculi. The procedure is often painful and requires large doses of analgesics. Many different anesthetic techniques have been used. Patients with either large bile duct calculi or pancreatic duct calculi which could not be extracted by routine endoscopic methods were selected. Thoracic epidural anesthesia (TEA) was routinely used in all the subjects unless contraindicated. Bupivacaine 0.25% with or without clonidine was used to block the segments D6 to D12. The dose was calculated depending on the age, height and weight of the patient. It was usually 1-2 mL per segment blocked.
RESULTS: Ninety eight percent of the 1509 patients underwent ESWL under TEA. The subjects selected were within American Society of Anesthesiologists grade I to III. ESWL using EA permitted successful elimination of bile duct or pancreatic calculi with minimal morbidity. The procedure time was shorter in patients with TEA than in those who underwent ESWL under total intravenous anesthesia.
CONCLUSION: Almost all patients undergoing ESWL with EA had effective blocks with a single catheter insertion and local anesthetic injection.

Abstract
BACKGROUND AND AIM Single-balloon enteroscopy (SBE) is a novel method of balloon assisted enteroscopy which allows deep intubation of intestine and has therapeutic potential. This prospective study was done in a tertiary care center to evaluate the feasibility, complications, diagnostic and therapeutic yield of SBE in patients with suspected small bowel disorders. METHODS One hundred and six patients (mean age 40.1 years, range 12-76 years, 65 men) with suspected small bowel diseases underwent 131 SBE procedures between February 2007 and July 2008. RESULTS Indications for SBE included obscure gastrointestinal bleeding (OGIB) (40), chronic abdominal pain with abnormal imaging studies (34), chronic diarrhea (20), polyposis syndromes (11) and foreign body (1).The mean insertion depth was 255.8 +/- 84.5 cm beyond the duodenojejunal flexure by the oral route and 163 +/- 59.3 cm proximal to the ileocecal valve by the per anal approach. The mean duration of the procedure for antegrade and retrograde enteroscopy was 65.9 +/- 19.5 min and 72.3 +/- 18.3 min, respectively. Pan-enteroscopy was possible in 25% of cases (five of 20 cases in which total enteroscopy was attempted). Diagnostic yields in cases of OGIB, chronic abdominal pain and chronic diarrhea were 60%, 65% and 55%, respectively. Overall new diagnosis was established in 46% and the extent of known disease was assessed in 15% of cases. In 21% of patients, therapeutic interventions were carried out while surgical treatment was directed to 8.4% of the patients. No major complications were observed. CONCLUSION SBE is well tolerated and has good diagnostic yield, having a similar yield to previous double-balloon enteroscopy reports.

Abstract
BACKGROUND AND AIM Difficult common bile duct stones (CBD) are those not amenable to extraction by the standard technique of sphincterotomy followed by use of a Dormia basket or balloon. The role of extracorporeal shock wave lithotripsy (ESWL) in stone fragmentation and clearance of difficult CBD stones and the factors which favor fragmentation were prospectively evaluated in the present study. METHODS A total of 283 patients with large CBD stones were subjected to ESWL. A maximum of 5000 shocks was delivered per session until CBD stones were fragmented to less than 5 mm diameter. CBD was cleared by biliary endotherapy using a basket or balloon. Outcome was assessed by CBD clearance. RESULTS Total CBD clearance was achieved in 239 patients (84.4%) and partial CBD clearance in 35 patients (12.3%). Three or fewer sessions of ESWL were required in 74.6% of patients. Minor complications were seen in 45 patients (15.9%). There was no procedure-related mortality. Epidural anesthesia, shock frequency of 90/min, radiolucent calculi and presence of fluid around the calculus helped in better fragmentation. CONCLUSION A high success rate, negligible complications and non-invasive nature of the procedure make ESWL a useful tool for removing large CBD stones.

Abstract
BACKGROUND Coeliac plexus block (CPB) is a management option for pain control in chronic pancreatitis. CPB is conventionally performed by percutaneous technique with fluoroscopic guidance (PCFG). Endoscopic ultrasound (EUS) is increasingly used for CPB as it offers a better visualization of the plexus. There are limited data comparing the two modalities. AIM To compare the pain relief in chronic pancreatitis among patients undergoing CPB either by PCFG technique or by EUS guided technique. METHODS Chronic pancreatitis patients with abdominal pain requiring daily analgesics for more than 4 weeks were included. Fifty six consecutive patients (41 males, 15 females) participated in the study. EUSG-CPB was performed in 27 and PCFG-CPB in 29 patients. In both the groups, 10 mL of Bupivacaine (0.25%) and 3 mL of Triamcinolone (40 mg) were given on both sides of the coeliac artery through separate punctures. RESULTS Pre and post procedure pain scores were obtained using a 0-10 visual analogue scale. Improvement in pain scores was seen in 70% of subjects undergoing EUS-CPB and 30% in Percutaneous- block group (P = 0.044). CONCLUSIONS EUS-guided coeliac block appears to be better than PCFG-CPB for controlling abdominal pain in patients with chronic pancreatitis.

Abstract
BACKGROUND Endoscopic transmural pseudocyst drainage is a multistep procedure. OBJECTIVE Our purpose was evaluation of a new device, the transluminal balloon accessotome (TBA) in transmural drainage of pancreatic pseudocysts. DESIGN Case series. SETTING Subspecialty tertiary care center. PATIENTS AND INTERVENTIONS Between September and October 2007, all consecutive patients with symptomatic pancreatic pseudocysts in whom TBA was used for pseudocyst drainage were included. Through a therapeutic duodenoscope, the pseudocyst was punctured with the needle-knife of the TBA at the point of maximal bulge. After the cyst cavity was entered, the needle-knife and the handle of the TBA device were withdrawn and a 0.035-inch guidewire was passed into the cavity. The tract was dilated with the inflatable balloon of the TBA device, and a 10F double-pigtail was inserted. RESULTS Six patients, all male, median age 35 years, underwent transmural pancreatic pseudocyst drainage with TBA during this period. All procedures were completed successfully. There were no major complications during or after the procedure except for fever in 1 patient, which responded to parenteral antibiotics. At 6-week follow-up, the pseudocyst cavity had completely collapsed, and stents could be extracted in all patients. LIMITATIONS Single-center experience, small sample size. CONCLUSIONS TBA is a safe, useful, and easy-to-use device for transmural drainage of pancreatic pseudocysts.

Abstract
CONTEXT The association of Santorinicele with pancreas divisum has been well described. There is an increased risk of recurrent acute pancreatitis in patients with pancreas divisum who also have Santorinicele. Focal saccular dilation of the terminal part of the main pancreatic duct has been described as an incidental finding and termed, 'Wirsungocele'. CASE REPORT We report a case of a 39-year-old male who had recurrent episodes of acute pancreatitis. Laboratory tests, US of the abdomen and CECT of the abdomen confirmed acute pancreatitis. MRCP showed focal saccular dilation of the terminal part of the main pancreatic duct suggestive of Wirsungocele. An ERCP confirmed MRCP findings. An endoscopic pancreatic sphincterotomy was performed and a 5 Fr single pigtail pancreatic stent was placed. The pancreatic stent was removed after 4 weeks. At the 12-week follow-up, the patient was asymptomatic. CONCLUSION This case report describes the association of Wirsungocele with recurrent acute pancreatitis.

Abstract
The main pancreatic duct and the common bile duct can be evaluated with a variety of evolving invasive and non-invasive techniques. Virtual CT pancreatoscopy obtained using special computer software is a recent non-invasive innovation which shows the details of the ductal surface (endoluminal view) with greater precision. The use of special computer software in MRI in order to obtain pancreatic ductal surface details or a virtual MR pancreatoscopy has not been described up to now. We report a short series of four patients suffering from chronic pancreatitis who underwent virtual MR pancreatoscopy with an impact on their management and clinical outcome.

Abstract
BACKGROUND AND AIM The presence of a critical intestinal stricture is a contraindication for conventional capsule endoscopy for the risk of impaction. Prior assessment of intestinal patency can substantially minimize this risk. The aim of the present study was to assess the safety and efficacy of the M2A patency capsule (PC) for verification of intestinal strictures. METHODS The M2A PC consists of a biodegradable body surrounding a small radiofrequency identification (RFID) tag. This capsule was administered to patients with known or suspected intestinal strictures. Patency was verified if the capsule was excreted intact. The capsule disintegrated into small fragments and only the RFID tag was excreted if retained at the stricture beyond a stipulated time. The patency scanner was used to detect the RFID tag externally. The M2A video capsule (VC) was administered to patients who excreted the intact capsule. RESULTS Twenty-six patients with known or suspected intestinal strictures were administered the M2A PC. This included 16 (61%) patients with tuberculosis, eight (31%) with Crohn's disease, and one each of postoperative and malignant strictures. Eight capsules were excreted intact within 72 h and two at 109 and 110 h. Fifteen capsules disintegrated in the G(I) tract and one capsule was removed during surgery. No PC-related complications were noted. Six of the eight patients who tested positive for patency were tested with the regular M2A VC with normal excretion. CONCLUSION The M2A PC is a reliable indicator of functional patency in suspected or even known cases of intestinal stricture. It could be used prior to conventional capsule endoscopy to predict and minimize the risk of impaction.

Abstract
BACKGROUND AND AIMS Endoscopic retrograde cholangiopancreatography (ERCP) requires adequate patient sedation in order to carry out the procedure successfully. Propofol sedation is being increasingly used during ERCP. There are limited data to evaluate the efficacy of synergistic agents with propofol for sedation during ERCP. The aims of the current study were: (i) to compare patient sedation and tolerance during ERCP using either propofol alone or a "sedato-analgesic cocktail" for induction, along with propofol for maintenance, and (ii) to prospectively compare complications related to both sedation regimens. PATIENTS AND METHODS This was a double-blind, randomized controlled trial with patients receiving either intravenous propofol alone (Group A) or a sedato-analgesic cocktail (midazolam, ketamine, and pentazocine plus propofol) (Group B) for induction; all patients received propofol for maintenance. Patient sedation and tolerance were assessed using 100-mm visual analog scales (VAS). RESULTS A total of 199 patients undergoing ERCP were randomized (Group A, n = 104 vs. Group B, n = 95). Clinical characteristics were similar in both groups. Patient tolerance VAS scores were higher in Group B when assessed independently by both endoscopist ( P = 0.002) and anesthetist ( P = 0.001). The differences in scores occurred predominantly in younger patients. The mean propofol requirement was 192 mg in Group A and 131 mg in Group B; the mean difference was 61 mg (95%CI 40-82 mg). Patients reported equivalent levels of satisfaction with both sedation regimens. On multivariate analysis, "cocktail" use ( P = 0.013) and increasing age ( P = 0.027) significantly improved patient tolerance during ERCP. Caution during "cocktail" induction is required as transient oxygen desaturation occurs. CONCLUSION During ERCP, propofol with a sedato-analgesic cocktail for induction results in improved patient tolerance compared with propofol alone, particularly in younger patients. Generalizations from this study to the Western world and to different cultural groups require further study.

Abstract
BACKGROUND Magnification endoscopy (ME), with 115-fold magnification, allows visualization of duodenal villi. We assessed the efficacy of ME for evaluation of villous atrophy. METHODS ME and duodenal biopsy were done in 16 patients with suspected celiac disease and 16 control subjects undergoing endoscopy for reflux symptoms. The pathologist was unaware of the ME findings. RESULTS Sensitivity, specificity and positive and negative predictive values for villous atrophy (partial or total) were 100%, 91%, 83% and 100%, respectively. Corresponding values for normal villous structure were 91%, 100%, 100% and 83%, respectively. There was significant concordance between the ME and histology findings. CONCLUSION ME is a reliable technique to diagnose villous atrophy.

Abstract
BACKGROUND Obscure gastrointestinal bleeding (OGIB) is a common indication for capsule endoscopy (CE). Reports on diagnostic yield of CE in this situation show a wide variation. We evaluated the diagnostic yield and clinical impact of CE in patients with OGIB. METHODS We reviewed the medical records of patients with OGIB who underwent CE at our institution between June 2002 and October 2005. RESULTS 154 patients (mean age 47 [SD 17] years; 117 men), including 74 with overt OGIB and 80 with occult OGIB, underwent CE. CE yielded positive findings in 57 of 74 patients (77%) with overt OGIB and 22 of 80 (27%) of those with occult OGIB (p < 0.0001); the overall positive diagnostic yield was 52%. NSAID-induced lesions (15%), angiodysplasias (14%) and aphthous ulcers (12%) were the most frequent findings. CE helped in planning further management in 79% of patients with overt OGIB and 26% of those with occult OGIB. CONCLUSION CE is a useful diagnostic technique in patients with OGIB, especially those with overt OGIB.

Abstract
AIM: To assess the efficacy of peginterferon alpha 2b at doses of 50 μg weekly and 80 μg weekly (based on body weight) plus ribavirin in HCV genotype 2 and genotype 3 chronic hepatitis C patients.
METHODS: During the study period of Jan 2002 to Dec 2003, all patients diagnosed as chronic hepatitis C or HCV related compensated cirrhosis were treated with peginterferon alpha 2b 50 μg S/C weekly (body weight < 60 kg) or 80 μg S/C weekly (body weight > 60 kg) plus ribavirin 800 mg/d for 24 wk.
RESULTS: Overall 28 patients, 14 patients in each group (based on body weight) were treated during the period. Out of 28 patients, 75% were genotype 3, 18% were genotype 2 and 7% were genotype 1. The mean dose of peginterferon alpha 2b was 0.91 μg/kg in group 1 and 1.23 μg/kg in group 2 respectively. The end of treatment and sustained virologic response rates were 82% and 78% respectively. Serious adverse effects were seen in 3.5% patients.
CONCLUSION: Low dose peginterferon alpha 2b in combination with ribavirin for 24 wk is effective in HCV genotype 2 and 3 chronic hepatitis C patients.

Abstract
AIM To assess the utility and efficacy of Rome I and Rome II criteria for the diagnosis of irritable bowel syndrome (IBS) in India. METHODS Patients referred with a diagnosis of IBS by general practitioners answered a questionnaire about clinical features, including those listed in the Rome I and Rome II criteria. All patients underwent investigations to determine the cause of their symptoms. Sensitivity, positive predictive value and percent agreement of final diagnosis with Rome I and II criteria were calculated. RESULTS Among 138 patients studied, 6 patients had organic disease . Amongst 132 patients with functional bowel disease, Rome I criteria diagnosed more patients as IBS than Rome II criteria (110 [83.3%] vs. 41 [31.1%]); 36 patients fulfilled both the criteria. Of the patients positive by Rome I, 32.7% fulfilled Rome II criteria, and of those diagnosed by Rome II criteria, 87.8% fulfilled Rome I criteria. Seventeen patients did not fulfill either Rome I or Rome II criteria, and were classified as functional abdominal bloating, functional diarrhea or functional constipation. CONCLUSION Rome I criteria are more sensitive than Rome II criteria for the diagnosis of IBS in the Indian population.

Abstract
INTRODUCTION Only limited data are available regarding the safety of therapeutic ERCP in pregnancy. We report our experience with therapeutic ERCP in pregnant women. METHODS Medical records of 18 pregnant women (first trimester 4, second 6, third 8) who underwent ERCP between July 1994 and December 2004 were reviewed. Patients and their families were contacted to assess the well being of mother and baby. RESULTS All the women underwent therapeutic ERCP and biliary sphincterotomy for common bile duct (CBD) stones. In 4 patients, 10-Fr CBD stents were inserted; three of these four cases required mechanical lithotripsy after delivery. Median procedure time was 17 min and median fluoroscopy time was 8 seconds. One patient each developed mild post ERCP pancreatitis and post sphincterotomy bleed. One woman had a preterm delivery. At follow up after a median of 6 years, all the babies were healthy. CONCLUSION Therapeutic ERCP can be performed safely in all the trimesters of pregnancy provided appropriate precautions are taken.

Abstract
Hepatitis B (HB) virus infection is a major health problem in dialysis dependent end stage renal failure (ESRF) patients. The sero-conversion rate after recombinant HB vaccine in ESRF patients is poor. Adjuvants like Granulocyte Macrophage-Colony Stimulating Factor (GM-CSF) have been found to improve response rate to vaccines. This study was conducted to evaluate the efficacy of GM-CSF as an adjuvant to HB vaccine in ESRF patients who were non-responders to the usual three double dose vaccinations (primary non-responders). Fifty consecutive HBsAg negative and anti-HBs negative ESRF patients on hemodialysis over thirty months were prospectively included (Jan. 96-June 98). All received 40 microg of recombinant HB vaccine at 0, 1, 2 month interval. Anti-HBs titres were subsequently tested after four weeks of the third dose. There were 19 (38%) primary non-responders (antiHBs negative). Twelve (Group I) of primary non-responders were given an additional dose of HB vaccine with 300 microg (5-6 microg/kg) of GM-CSF (Leucomax) and the remaining seven (Group II) received only an additional dose of HB vaccine. Anti-HBs was determined by Abbott's ELISA kit, and titre above 10 mIU/mL was considered as protective. In Group I, sero-protective titres were obtained in 11 out of 12 (91.6%) patients, whereas in Group II none of the patients achieved sero-protection (p < 0.001). The sero-conversion rate improved from initial 62% (31/50) to overall 84% (42/150) after the use of GM-CSF. There were no adverse events noted with the use of GM-CSF. At one year, 24 out of 32 (75%) who were sero-protected earlier continued to remain sero-protected. This study indicates that GM-CSF is a potent HB vaccine adjuvant for sero-conversion in primary non-responders.

Abstract
INTRODUCTION Falciparum malaria occasionally presents with encephalopathy, jaundice and fever mimicking fulminant hepatic failure. PATIENTS We recently managed seven cases (mean age 34 years, range 20-45; all men) of acute falciparum malaria presenting with a short history [mean duration 8.1 (4-15) days] of fever, jaundice, altered sensorium and oliguria. Only one patient had splenomegaly. Investigations revealed jaundice (bilirubin 1.9-30.7 mg/dl), moderate to severe anaemia (Hb 4-8 gm/dl), increased liver enzymes (2-4 times normal) and azotaemia (serum creatinine 1.6-7.4 mg/dl). Coagulation parameters were deranged in 3 with clinical bleeding in two cases. One patient without a past history of diabetes had increased blood glucose values with ketonuria. HBsAg was negative in all cases. Patients received supportive therapy along with intravenous quinine. Peritoneal dialysis was done in one patient. Three patients showed rapid recovery and four succumbed to the disease. Post-mortem liver biopsy showed Kupffer cell hyperplasia, pigment deposition, foci of steatosis and necrosis along with submassive necrosis in one case. CONCLUSIONS In areas endemic for malaria, awareness of this entity is a must. In a patient with jaundice and altered sensorium, disproportionate anaemia, azotaemia and only mild elevation of liver enzymes should help differentiate these patients from cases of fulminant hepatic failure. The diagnosis can be confirmed by peripheral blood examination. Early institution of specific therapy may be the only life saving measure in these patients.

Abstract
The effect of single dose of three different types of high cholesterol diet on plasma total cholesterol (PTC) in 24 young healthy subjects (male:female = 1:1) aged 15 to 35 years was studied. One group (n1 = 8) was given a butter and milk diet (300 mg cholesterol and 95 g fat). In the first postprandial hour PTC level increased significantly in all but one subject (mean +/- S.D., 4.96 +/- 0.57 m mol/l to 5.61 +/- 0.60 m mol/l, P < 0.005). Second group (n2 = 8) was given a single egg diet (300 mg cholesterol and 6 g fat). In the first hour the PTC level decreased significantly in all but 2 subjects (4.82 +/- 0.58 m mol/l to 4.42 +/- 0.63 m mol/l, P < 0.02). Third group subjects (n2(3) = 8) were given a test diet consisting of crystalline cholesterol with 200 ml milk (1020 mg cholesterol and 14 g fat). The PTC level increased insignificantly. In the first hour in all but 2 subjects (4.94 +/- 0.43 m mol/l to 5.35 +/- 0.88 m mol/l, P > 0.10). In the third postprandial hour the PTC values in all the 3 groups showed a tendency to return to fasting values. Therefore, we conclude that the effect of dietary cholesterol on PTC depends not only on the amount of cholesterol content in the diet, but on the type of diet (cholesterol vehicle) as such and probably also on the fat content of the diet.
