Double pylorus is a rare condition consisting of a double communication between gastric antrum and duodenal bulb; in most cases it is a complication of penetrating ulcer, sometimes it is a congenital abnormality. The prevalence of this rare anomaly ranges from 0.02% to 0.13%; the male:female ratio is about 2:1. Two cases of acquired double pylorus are reported with a review of the literature. The first case represented an occasional report; in the other one the development of double pylorus from confluent prepiloric and bulbar ulcers was documented through serial endoscopies. Both patients were affected with chronic renal failure and referred previous treatment with diclofenac; however, their relationship with double pylorus onset remains unproven.
双幽门是一种罕见的情况，由胃窦和十二指肠球部之间的双重连通组成；在大多数情况下，它是穿透性溃疡的并发症，有时是先天性异常。这种罕见异常的患病率在0.02%至0.13%之间；男女比例约为2:1。本文报告了两例获得性双幽门病例并对文献进行了综述。第一例是偶然报告；另一例通过连续内镜检查记录了由融合的幽门前和球部溃疡发展而来的双幽门。两名患者均患有慢性肾衰竭，且之前均接受过双氯芬酸治疗；然而，它们与双幽门发病之间的关系仍未得到证实。
