目的探讨小肠胃黏膜异位并发消化道出血的临床诊断与治疗。方法对我院24年间收治的11例小肠胃黏膜异位并发消化道出血的病例资料进行回顾性分析。结果11例患者发病中位年龄29岁。其中9例发病有腹痛。常规内镜检查均无阳性发现；6例于手术前行放射性~(99m)锝核扫描均有放射性示踪剂吸收和浓集；1例肠系膜钡餐示末段回肠重复畸形；1例选择性肠系膜血管造影发现近端空肠出血。本组病例均行病变部位小肠段切除,术后病理报告均为胃黏膜异位症,其中病变位于空肠者5例,回肠者6例。11例病灶与肠憩室、肠壁炎性肿块、肠重复畸形并存。11例术后均痊愈出院。结论放射性~(99m)锝扫描对小肠胃黏膜异位症术前诊断有重要意义；手术治疗有效。
Objective To investigate the clinical diagnosis and treatment of gastrointestinal mucosal ectopic gastrointestinal hemorrhage. Methods A retrospective analysis was performed on 11 cases of gastrointestinal mucosal ectopic gastrointestinal bleeding treated in our hospital for 24 years. Results The median age of 11 patients was 29 years old. Nine of them had abdominal pain. Radiological 99m Tc nuclear scintigraphy was performed in all 6 patients with radioactive tracer absorption and concentration before radiography; 1 case of mesenteric barium meal showed terminal ileum deformity; 1 case of selective mesentery Angiography revealed proximal jejunal hemorrhage. All patients underwent pathological resection of the small intestine, and postoperative pathological reports were all gastric mucosal ectopic. Among them, 5 were located in the jejunum and 6 were ileum. 11 cases of lesions and intestinal diverticulum, intestinal wall inflammatory mass, intestinal deformity co-exist. Eleven patients were cured after surgery. Conclusion Radioactive 99m Tc scan has important significance for preoperative diagnosis of small intestine gastric mucosa. Surgical treatment is effective.
