摘　　要：Double pylorus(DP), or duplication of the pylorus, is an uncommon condition that can be either congenital or acquired. Acquired DP(ADP) occurs when a peptic ulcer erodes and creates a fistula between the duodenal bulb and the distal stomach. The clinical features and endoscopic characteristics of four patients with ADP were reviewed and compared with previously reported cases. An accessory channel connects the lesser curvature of the prepyloric antrum with the duodenal bulb, and in all cases, a peptic ulcer was located in or immediately adjacent to the accessory channel. In one of the patients, the bridge between the double-channel pylorus disappeared, resulting in a single large opening and duodenal kissing ulcer after two years and three months. Finally, nonsteroidal anti-inflammatory drugs, Helicobacter pylori and other risk factors associated with ADP are assessed.Double pylorus(DP), or duplication of the pylorus, is an uncommon condition that can be either congenital or acquired.
