本文分析１２９例幽门管溃疡临床及内镜特点。患者多数有类似十二指肠溃疡的饥饿性腹痛，且出血、呕吐和幽门梗阻的发生率显著高于一般胃溃疡和十二指肠溃疡（Ｐ＜０．０５）。溃疡多发生在幽门前区小弯侧，多数溃疡呈圆形或椭圆形，直径＜１Ｏｍｍ，且多为浅凹状。幽门孔周常充血、水肿、变形及形成假幽门。Ｘ线钡餐或内镜检查时如不仔细观察易误诊为球部溃疡。 This article analyzes 129 cases of pyloric ulcer clinical and endoscopic features. The majority of patients had hunger-like abdominal pain similar to duodenal ulcer, and the incidence of bleeding, vomiting and pyloric obstruction was significantly higher than that of general gastric ulcer and duodenal ulcer (P <0.05). Occurred in the small ulcers in the pyloric front ulcer, the majority of ulcers were round or oval, diameter <1Omm, and mostly shallow concave. Pyloric cavity often congestion, edema, deformation and the formation of false pylorus. X-ray barium meal or endoscopy if not carefully observed easily misdiagnosed as a ball ulcer.
