Radiographic and clinical features in five patients with the double channel pylorus deformity are reviewed and compared with previously reported cases. The double channel pylorus is a form of gastroduodenal fistula with a characteristic radiographic appearance. An accessory channel connects the lesser curvature of the prepyloric antrum with the duodenal bulb. A peptic ulcer lies in or immediately adjacent to the accessory channel in almost all cases. The double channel pylorus appears to be an acquired form of peptic deformity in the great majority of cases and is probably more common than the number of reported cases would imply.
回顾了5例双通道幽门畸形患者的影像学和临床特征，并与先前报道的病例进行了比较。双通道幽门是胃十二指肠瘘的一种形式，具有特征性的影像学表现。一条副通道将幽门窦前壁的小弯侧与十二指肠球部相连。几乎在所有病例中，消化性溃疡都位于副通道内或紧邻副通道。在绝大多数情况下，双通道幽门似乎是一种后天获得性的消化性畸形，其实际发生率可能比已报道病例数所显示的更为常见。
