A gastric diverticulum containing pancreatic tissue and presenting as congenital double pylorus: case report and review of the literature.

Abstract

Double pylorus is a rare condition consisting of a double communication between the gastric antrum and the duodenal bulb. Double pylorus can occur as a congenital abnormality or as a complication of peptic ulcer disease. Although almost 100 patients with acquired double pylorus have been described (1,2), only a few patients with congenital double pylorus have been described, and, in only one patient, this anomaly was recognized in childhood (3). Herein we describe another child with congenital double pylorus, who presented with gastric outlet obstruction.
