RESUMEN
BACKGROUND: Endoscopic management of recurrent bile duct stones after endoscopic sphincterotomy (EST) is effective and safe. However, repeat EST for extension of a previous EST for recurrent bile duct stones may involve substantial risk. The aim of the present study was to evaluate the safety and efficacy of endoscopic papillary large balloon dilation (EPLBD) without repeat EST for recurrent difficult bile duct stones after previous EST. PATIENTS AND METHODS: From January 2006 to October 2010, a total of 52 patients were enrolled; all had undergone EPLBD (balloon diameter: 12-20 mm) to remove recurrent difficult bile duct stones after previous EST. In all patients, stone removal had failed with conventional methods using a basket and/or balloon. The size of the balloon for EPLBD was selected to fit the diameter of the common bile duct or the largest stone. RESULTS: The median interval between initial EST and stone recurrence was 2.2 years (range 1-10). Median diameters of thelargest stone and balloon were 20.1 mm (range 12-40) and 14.7 mm (range 12-20), respectively. Complete stone removal was achieved in all patients (100%). The median number of endoscopic retrograde cholangiopancreatography sessions needed for complete stone removal was 1.6 (range 1-3). Additional lithotripsy was required in 16 patients (30.7%). No procedure-related complications were documented, with the exception of four cases of asymptomatic hyperamylasemia. The recurrence rate of CBD stones after bile duct clearance was 17.3% (9/52) during the follow-up period (mean 27.0 ± 14.1 months). CONCLUSIONS: EPLBD without repeat EST is effective and relatively safe for the extraction of recurrent difficult bile duct stones after previous EST.

BACKGROUND: High-quality bowel preparation is a prerequisite for colonoscopy. Few studies have evaluated visual aids as a means of improving the quality of bowel preparation. OBJECTIVE: To assess the effect of patient education by using cartoon visual aids on the quality of bowel preparation. DESIGN: An endoscopist-blinded, randomized, controlled trial. SETTING: Tertiary referral center. SUBJECTS: Patients scheduled for screening colonoscopy in a health examination center. INTERVENTIONS: Patients were assigned to receive the existing verbal and written instructions (group A) or a new cartoon visual educational instruction (group B) for colonoscopy. MAIN OUTCOME MEASUREMENTS: The primary endpoint was the quality of bowel preparation, assessed by using the Boston Bowel Preparation Scale (BBPS). Secondary endpoints were the quality of bowel preparation assessed by using the Universal Preparation Assessment Scale; insertion, withdrawal, and workup times; and polyp detection rates in the 2 groups. Logistic regression analysis was performed to determine the factors associated with poor bowel preparation according to a BBPS score less than 5. RESULTS: Group B exhibited better bowel preparation than group A according to BBPS scores (mean BBPS score, 6.12 ± 2.19 vs 7.44 ± 1.87, P ≤ .01; median BBPS score, 6.00 ± 0.00 vs 9.00 ± 0.00, P ≤ .01; good bowel preparation for colonoscopy, BBPS score ≥5, 81.6% vs 93.1%, P = .02). Multivariate analysis revealed that older age (odds ratio 1.07, P ≤ .01) and no use of visual aids (odds ratio 3.08, P = .02) were independent factors associated with poor bowel preparation. LIMITATIONS: Single-center study. CONCLUSIONS: Patient education with cartoons effectively improved bowel preparation for colonoscopy.

Previously reported series suggested that the morbidity rate of internal surgical drainage procedure alone was about 15% and the mortality rate was less than 5% in patients with pancreatic pseudocysts. Recently, ultrasonography or CT-guided percutaneous drainage and endoscopic drainage techniques have created a new dimension of invasive, non-surgical treatment options for these patients. In the absence of prospective, randomized, controlled studies comparing outcomes of different pseudocysts drainage techniques, the decision as to which method should be employed often lies with local expertise and enthusiasm. In our experience, radiologic percutaneous drainage with subsequent transpapillary endoscopic drainage had a high success rate and was relatively less difficult which resulted in rapid clinical improvement. We report three cases of pancreatic pseudocysts treated with percutaneous drainage as a first-line treatment followed by endoscopic treatment.

BACKGROUND/AIMS: Endoscopic stent insertion with self expandable metal stent (SEMS) is one of the standard palliative treatments for the patients with unresectable bile duct carcinoma. The aim of this study was to determine whether detection of longitudinal spread of extrahepatic bile duct carcinoma by intraductal US (IDUS) would be helpful in the selection of metal stent for the palliative drainage in bile duct carcinoma. METHODS: Seventeen patients with histologically proven unresectable extrahepatic bile duct carcinoma who underwent endoscopic retrograde cholangiography with IDUS were included. Longitudinal cancer extension along the bile duct was determined and, then, compared with the cholangiographic image. The type and length of SEMS was selected based on IDUS findings. RESULTS: IDUS demonstrated more extensive tumor spread than ERC in 7 of 17 (41.2%) patients with the hepatic side of strictures and in 7 of 16 (43.8%) patients with the duodenal side of strictures. Five of 17 (29.4%) patients have changed the plan of endoscopic biliary drainage with SEMS after IDUS. There was no early dysfunction associated with endoscopic biliary drainage. CONCLUSIONS: IDUS prior to biliary drainage would be useful in demonstrating longitudinal extension of extrahepatic bile duct carcinoma. It has a potential role in helping stent selection and identifying factors which predict early stent dysfunction.

A secondary aortoenteric fistula (AEF) is a direct communication between the gastrointestinal tract and the aorta in a patient who has undergone major surgery on the aorta, often an aorta graft operation. We experienced a patient who had undergone graft interposition for abdominal aortic aneurysm and was admitted due to three episodes of hematemesis and following hamatochezia. Gastroscopy, colonoscopy, and radioactive iodine scan failed to identify the bleeding site in the patient. He was diagnosed with AEF by double balloon enteroscopy and recovered after surgical intervention.
