目的 对 23例先天性肠道重复畸形患儿的临床症状、诊断方法及治疗予以总结。方法 22例患儿均有反复且无明显腹部症状的下消化道出血，术前有 15例用 99mTc检查，全部患儿术中切除重复的肠管及部分正常肠管后、行正常肠管端端吻合术。结果 报告小肠腔内有放射性分泌物异常积存，提示肠腔内有异位胃粘膜或出血灶。结论 无明显症状不明原因的下消化道反复出血、排除下消化道炎症、肿瘤、凝血机制障碍等疾病后，应考虑先天性肠道重复畸形出血的可能。该疾病可因肠道感染或胃及胰腺粘膜异位产生酸或碱性物质，腐蚀肠粘膜及血管破裂而产生大出血。 99mTc检查效果良好，出血时检查阳性率高且为无创性。切除病变，预后良好。
Objective To summarize the clinical symptoms, diagnosis and treatment of 23 patients with congenital intestinal deformity. Methods Twenty-two children underwent repeated lower gastrointestinal bleeding without obvious abdominal symptoms. Fifteen patients were examined with 99mTc before surgery. All patients underwent resection of the intestine and part of normal intestine during operation, and then received normal intestinal end-to-end anastomosis . The results report an abnormal accumulation of radioactive secretions in the small intestine, suggesting that there is ectopic gastric mucosa or hemorrhage in the intestine. Conclusion No obvious symptoms of unexplained gastrointestinal repeated bleeding, remove the lower gastrointestinal inflammation, cancer, coagulation disorders and other diseases, should consider the possibility of congenital intestinal deformity bleeding. The disease may be due to intestinal infection or gastric and pancreatic mucosa ectopic acid or alkaline substances generated, the erosion of the intestinal mucosa and blood vessels rupture and bleeding. 99mTc examination results are good, the positive rate of bleeding examination and non-invasive. Excision of the disease, the prognosis is good.
