Abstract

Double pylorus is either a congenital abnormality or an acquired complication of peptic ulcer disease. An accessory channel normally connects the lesser or greater curvatore of the prepyloric antrum with the duodenal bulb. Three cases of double pylorus, an unusual complication of peptic ulcer disease is herein reported. A peptic ulcer lay in the accessory channel in all cases. In one of the cases, the fistula closed spontaneously after Helicobacter pylori eradication. The remaining 2 patients became asympto-matic despite the persistence of the accessory channel.
