[Endoscopic evaluation of reflux gastritis in patients operated on for stomach and duodenal ulcers].

An analysis of results of the endoscopic examination of 320 patients who had been subjected to various operations for ulcer disease of the stomach and duodenum has shown that sphincter-preserving operations (selective proximal vagotomy without drainage of the stomach and pylorus-preserving resection of the stomach) in treatment of ulcer disease of the stomach and duodenum with correction of disturbances of duodenal passability is the most reliable method for prevention of duodeno-gastric reflux and reflux-gastritis.
