[The interposed jejunal loop after resection for gastric ulcer (endoscopic study)].

Authors refer about an endoscopic study concerning twenty patients who have been previously operated for gastric ulcer. In these patients it was performed a reconstruction of the alimentary canal by means of a gastro-duodenal interposition of an isoperistaltic jejunal loop. Authors show that this method has been proved valid to prevent duodeno pancreatic reflux in the residual gastric sac.
