Gastroduodenal endoscopic examination revealed an oval-shaped submucosal tumor at the prepyloric area on the posterior wall of the stomach. A degenerated gastrointestinal stromal tumor was suspected. Distal gastrectomy was performed and a histological diagnosis of heterotopic pancreas （HPs） was confirmed. The patient had an uneventful postoperative course and was discharged 7 d a^er operation. The patient remains healthy and symptom-free in the follow-up of 6 mo. This is a report of a case of gastric outlet obstruction resulting from pancreatic heterotopia in the gastric antrum in an adult woman.展开更多

METHODS:Fifteen consecutive patients underwent peroral placement of Wallstent^(TM)Enteral Endoprosthesis to treat gastric outlet and duodenal obstructions(14 malignant,1 benign).All procedures were completed under fluoroscopic guidance without endoscopic assistance.Follow-up was completed until the patients died or were lost,and the clinical outcomes were analyzed. RESULTS:The technique success rate was 100%,and the oral intake was maintained in 12 of 14 patients varying from 7 d to 270 d.Two patients remained unable to resume oral intake,although their stents were proven to be patent with the barium study.One patient with acute necrotizing pancreatitis underwent enteral stenting to treat intestinal obstruction,and nausea and vomiting disappeared.Ten patients died during the follow- up period,and their mean oral intake time was 50 d. No procedure-related complications occurred.Stent migration to the gastric antrum occurred in one patient 1 year after the procedure,a tumor grew at the proximal end of the stent in another patient 38 d post-stent insertion. CONCLUSION:Fluoroscopically guided peroral metal stent implantation is a safe and effective method to treat malignant gastrointestinal obstructions,and complications can be ignored based on our short-term study.Indications for this procedure should be discreetly considered because a few patients may not benefit from gastrointestinal insertion,but some benign gastrointestinal obstructions can be treated using this procedure.展开更多
