下消化道出血922例纤维结肠镜检查结果分析

FIBEROPTICAL COLOSCOPY IN 922 PATIENTS WITH LOWER GASTROINTESTINAL HEMORRHAGE

总结了下消化道出血922例患者纤维肠镜检查的结果。922例中,结肠息肉354例,占38.4％,息肉癌变19例,占5.36％,癌变以绒毛状腺瘤最多,占47％。本组大肠癌便血者134例,占同期结肠镜检查下消化道出血患者的14.5％;炎症性肠病50例,占本组下消化道出血5.4％;其余病例见于结肠特异性和非特异性感染,如肠结核、肠阿米巴病、血吸虫病、非特异性孤立性溃疡等。少见病例见于结肠憩室、血管瘤、及鞭虫感染等均不同程度导致下消化道出血。并分别讨论了不同病因所致下消化道出血的内镜下表现。

Lower gastrointestinal (GI) bleeding with different causes was studied with fiberoptic coloscopy in 022 patients,and the endoscopic features were discussed.Of the 922 cases,colonic polyps were identified in 354 cases (38.4%),and neoplastic polyps in 10 (5.36%).in which villous adenomas was the most common,accounting for 47%.Large intestinal cancers were diagnosed in 134 cases (14.5%) and inflammatory bowel disease in 50 cases (5.4%).The etiology of the bleeding also included infectious diseases in colon,such as tuberculosis,amebiasis,schistosomiasis,idiopathic solitary colonic ulcer.Rarer causes of the lower GI hemorrhage included di-verticulum,hemangioma and trichuriasis.
