Utilizing an equal mixture of 5% sodium morrhuate and 60% renografin, we studied four patients during a total of nine sessions of injection sclerotherapy of esophageal varices to determine radiographically the fate of injected sclerosant. Despite attempted intravariceal injections, 44% resulted in local and presumably paravariceal accumulation of contrast(More)
BACKGROUND The gastroenterology community's experience with esophageal self-expandable metallic stents (SEMS) is unknown. METHODS In order to assess indications, perioperative management, and self-reported complications associated with SEMS placement, a survey was mailed to ASGE members. RESULTS Of 3414 surveys mailed, 212 (6.2%) were completed and(More)
The American Society for Gastrointestinal Endoscopy has promulgated guidelines on quality assurance in gastrointestinal endoscopy. Thorough documentation of endoscopy reports and a peer review process were strongly recommended. We evaluated 1408 dictated endoscopy and colonoscopy reports for deficiency in reference to the guidelines during three periods: 6(More)
Results from 120 patients managed with a Sacks-Vine gastrostomy tube were analyzed. In our experience, this device can be successfully placed in almost all cases (96%), and has a low rate for procedure-related mortality (0.8%) and major (4.4%) and minor (12.4%) complications. Advantages and problems associated with this feeding catheter are discussed. The(More)
To assess the success rates and complications of esophageal foreign body extraction in adult and pediatric patients, the charts of 76 adults and 116 children with endoscopically or radiographically documented esophageal foreign body impaction were retrospectively reviewed. Success rates for rigid esophagoscopy (100%) and flexible endoscopy (96.2%) were not(More)
Push-enteroscopy using a disinfected colonoscope was performed on 39 patients with gastrointestinal bleeding of obscure origin. Our results show that: (1) A high percentage of patients (38%) have pathological lesions responsible for bleeding located in the distal duodenum and proximal jejunum, which are readily detected by push-enteroscopy. (2)(More)
Bipolar probe coagulation (BICAP) was evaluated and compared with conventional cold biopsy (CBx) as a potential therapeutic modality for eradication of diminutive colonic polyps (DPs). Seventy-seven and 79 DPs were treated with BICAP and CBx, respectively. Twenty-one percent of the BICAP and 29% of the CBx (p greater than 0.05) group had residual polypoid(More)
Fifty consecutive patients with bleeding esophageal varices were treated with endoscopic variceal sclerotherapy (EVS) using the free hand method and a flexible fiberoptic endoscope. During the study period, November 1981 through April 1984, 11 patients (22%) rebled after the initiations of EVS and six patients were lost to follow-up. Obliteration of(More)
Enlarging pancreatic pseudocysts, as well as those that develop complications such as bleeding, leak, infection, and intestinal or biliary obstruction, require treatment. This treatment is usually surgical and consists of internal or external drainage or, less commonly, excision. Transcutaneous aspiration with or without drain placement has also been(More)
Although recommended for patients requiring frequent dilations in whom surgery is not feasible, self-bougienage for benign esophageal stricture has not been examined critically. Thirteen patients performing self-dilations over a mean period of 4.8 years were evaluated. Dysphagia decreased in all patients and reflux symptoms were well-controlled in most(More)
