黑便常常被认为是上消化道出血的指征,但它也可山结肠病变引起。本文研究了纤维结肠镜对黑便病人的诊断作用,这些病人经上胃肠道内窥镜检查阴性,上、下胃肠钡剂检查均未发现病变。放射线检查中发现有可能造成出血的病变(除憩室外)者则不列入本组中。结果 626例怀疑下胃肠道出血的病人做了全结肠镜检查。55例有黑便,其中2例经放射线证实为右半结肠癌而从研究组中除外,53例作为本组研究对象。
Black is often considered an indication of upper gastrointestinal bleeding, but it can also cause mountain colic lesions. In this paper, we studied the diagnostic value of fibro-colonoscopy for patients with melena. None of the patients were found to have pathology by upper gastrointestinal tract endoscopy, upper and lower gastrointestinal barium examination. Radiological examination found that there may be bleeding lesions (except diverticular disease) were not included in this group. Results A total colonoscopy was performed in 626 patients with suspected gastrointestinal bleeding. 55 cases were melena, of which 2 cases were confirmed by radiography right colon cancer and excluded from the study group, 53 cases as the study group.
