Three Cases of Double Pylorus Due to Gastroduodenal Fistula Complicating Peptic Ulceration: Disappearance of gastroduodenal fistula in 1 case after eradication of a Helicobacter pylori infection / 대한소화기내시경학회지

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.
