异位胰腺发生于肠道比较多见,但发生于胃壁者甚为少见,我院自1977～1987年经手术及病理证实胃壁异位胰腺组织4例。其中有2例纤维胃镜诊断为“胃窦部息肉”,活检诊断分别为重度、中度慢性浅表性胃炎。术前均误诊为肿瘤,报告如下(附表)。讨论胃壁异位胰腺组织甚为少见,我院1977年以来,行胃大部切除1,198例,仅见4例。占胃切除标本的3‰。本病发生机理尚不清楚,一般认为与胚胎发育异常有关。本组4例,均发生在胃窦部及幽门环区。3例位于粘膜下,1例位于肌层中,文献报告,肿物一般较小,6cm以上者极少见,本组为1.5-4cm。肉眼观呈淡黄色或淡红色的单个分
Ectopic pancreas occurred in the intestine more common, but it is very rare in the stomach wall. Our hospital from 1977 to 1987 by surgical and pathological confirmation of ectopic pancreatic tissue in 4 cases. There were 2 cases of gastroscopic diagnosis of “gastric sinus polyps,” biopsy diagnosis was severe, moderate chronic superficial gastritis. Preoperatively misdiagnosed as a tumor, the report is as follows (annex table). Discussion of ectopic pancreatic tissue in the stomach wall is rare. Since our hospital began in 1977, 1,198 cases have undergone major gastrectomy and only 4 have been seen. 3% of the total gastrectomy specimen. The mechanism of this disease is not yet clear, and it is generally considered that it is related to abnormal embryonic development. Four patients in this group occurred in the gastric antrum and pylorus. 3 cases were located in the submucosa and 1 case was in the muscular layer. The literature reported that the tumors were generally small, and those 6cm or more were rare. This group was 1.5-4cm. A single point of light yellow or light red in the naked eye
