The stomach temporarily stores food and secretes gastric juices to break down and digest food. The normal process is the movement of food digested from the stomach to the duodenum, with the pylorus as a passageway. This paper reports the case of a patient with an ectopic gastric pylorus who presented with gastrointestinal bleeding. A 62-year-old man complained of melena with mild dizziness and nausea. An endoscopic examination revealed a gastric ulcer, approximately 1 cm in diameter, and exposed blood vessels on the posterior wall of the upper body. No normal pyloric structure was observed in the distal antrum, and an opening leading to the duodenum was noted in the posterior wall of the upper body adjacent to the ulcer. This case presents a congenital pyloric ectopic opening in the upper body of the stomach, not in the distal antrum, suggesting a rare gastric morphological variation.
胃暂时储存食物，并分泌胃液以分解和消化食物。正常过程是食物从胃消化后通过幽门移动到十二指肠。本文报告了一例异位胃幽门患者出现胃肠道出血的病例。一名62岁男性主诉有黑便，伴有轻度头晕和恶心。内镜检查发现一个直径约1厘米的胃溃疡，在上部后壁有暴露的血管。在胃窦远端未观察到正常的幽门结构，在与溃疡相邻的上部后壁发现一个通向十二指肠的开口。该病例显示胃上部存在先天性幽门异位开口，而非胃窦远端，提示一种罕见的胃形态变异。
