Arteriomesenteric Obstruction of the Duodenum and Peptic Ulcer

Abstract

Obstruction and dilatation of the duodenum are caused by a variety of diseases. Chronic intermittent arteriomesenteric obstruction (AMO) is the most common of the extrinsic disorders that cause duodenal obstruction. The diagnosis of the AMO is based on the symptoms and radiological findings. We present 3 cases of AMO of the duodenum with peptic ulcer treated by duodenojejunostomy and highly selective vagotomy. The diagnostic and clinical problems that are caused by the coexistence of AMO with peptic ulcer and the treatment indicated are discussed.
