[Gastric resection with preservation of the pyloric sphincter in treating patients with duodenal ulcer].

An experience with pylorus-preserving resections of the stomach in 27 patients with duodenal ulcer and very high acid production is described. Specific technical features of this operation, immediate and long-term results are analyzed. Rhythmic evacuation was preserved in addition to a reliable drop of the acid production. Gastroduodenal reflux was prevented. Positive results were noted in all the examined patients in the remote follow-up.
