Congenital pyloric atresia: a report of three cases.

Congenital pyloric atresia, a rare malformation producing gastric outlet obstruction during the neonatal period, was found in three patients. Sixty per cent of these malformations are membranous in type. Excision of the membrane and Heineke-Mikulicz pyloroplasty, which has been advocated as the procedure of choice, inevitably results in postoperative duodenogastric bile reflux. We suggest that to minimize reflux and hence possible increased risk of future development of gastric ulcer, maximal preservation of pyloric function in the operative management of the malformations is important.
