Congenital double pyloric ostium in the adult.

Duplication of the pylorus, an extremely rare congenital anomaly of the stomach, consists of two openings connecting the antrum of the stomach to the duodenal bulb. Approximately 70 cases of double pylorus have been described in the literature, most of which are associated with the presence of chronic peptic ulcers, thus indicating an acquired origin of the condition. We report a case of congenital double pylorus in a 64-year-old man who complained about mild postprandial epigastric discomfort and nausea of approximately 3 months' duration.
