BACKGROUND Normal saline (NS) plus epinephrine (E) is the traditionally used solution as submucosal fluid cushion for a safe and effective endoscopic mucosal resection (EMR) of sessile colorectal polyps. It was hypothesized that hydroxyethyl starch (HES), an inexpensive and easily available solution might be an ideal solution for prolonged elevation of(More)
BACKGROUND Ingested foreign bodies and food bolus impaction are frequently seen in endoscopic practice. Successful foreign body and food bolus removal may depend on the method used, the choice of device, and the experience level of the endoscopist, although few papers report experience and outcome of tertiary centers. AIM To investigate the effectiveness(More)
A 76-year-old diabetic man underwent cholecystectomy for gangrenous calculous cholecystitis. His postoperative course was complicated by the development of Candida albicans esophagitis necessitating antifungal therapy, and total parenteral nutrition (TPN) for 15 d. Seven weeks after cholecystectomy, he presented with cholangitis. Endoscopic retrograde(More)
Colonic lipomas are uncommon nonepithelial neoplasms that are typically sessile, asymptomatic and incidentally found during endoscopy, surgery, or autopsy. We present a very rare case of a 34-year-old female patient with symptomatic pedunculated cecal lipoma causing intermittent colo-colonic intussusception. Despite adequate imaging studies, definite(More)
BACKGROUND EMR traditionally performed by using normal saline solution (NS) plus epinephrine (E) as a submucosal fluid cushion does not maintain the submucosal elevation for a prolonged time. It was hypothesized that 50% dextrose (D(50)) plus E as a hypertonic, inexpensive, and easily available solution might be an ideal alternative for producing and(More)
BACKGROUND Biliary decompression is a key factor in the treatment of postcholecystectomy bile leak. However, the optimal size of the stent introduced by therapeutic endoscopic retrograde cholangiopancreatography (ERCP) is yet to be determined. The aim of the study was to compare the effectiveness of two straight plastic stents with different sizes (10-Fr(More)
Lateral spreading tumors (LSTs) of the colon are lesions over 10 mm in diameter that are low in height and grow superficially. They are increasingly being diagnosed in Western cohorts. The aim of this study was to investigate the safety and efficacy of dextrose 50% solution in the endoscopic mucosal resection (EMR) of LSTs. The study population consisted of(More)
BACKGROUND The aim of this retrospective study was to evaluate the success rate and complications of three precut techniques of sphincterotomy after failure of conventional techniques of cannulation of common bile duct (CBD). PATIENTS AND METHODS Between January 2003 and October 2011, 2,903 consecutive ERCPs were performed in patients with naïve major(More)
BACKGROUND Endoscopic retrograde cholangiopancreatography (ERCP) is now the exclusive endoscopic therapeutic modality for biliary as well as pancreatic diseases. The aim of the present study was to investigate patient- and procedure-related risk factors for post-ERCP complications in a large-scale study of procedures performed by a single experienced(More)
BACKGROUND Endoscopic stent insertion is the optimum method of palliation for malignant biliary obstruction. Various types of self-expanding metal stents have been introduced in the market. Whether one type of stents is superior to the others in terms of stent patency remains undefined. GOALS This randomized trial compared 2 uncovered metal stents with(More)
