临床上有关结肠检查的方法很多,本文就纤维乙结肠镜加气钡对比造影(ACBE)与全结肠镜对下消化道出血的初步诊断性检查价值进行一项随机对照研究。材料与方法:322例≥40岁的下消化道出血者被随机地分为两组,a组:接受全结肠镜检查164例;b组:接受纤维乙结肠镜检查加ACBE 168例。ACBE与纤维乙结肠镜检查安排在同一天内进行。全结肠镜检查时镜管须插至盲肠末端,乙结肠镜检查至少插入30cm。结果:161例(96％)接受纤维乙结肠镜检查者插入顺利,平均插入深度为50cm。31人(18％)无异常发
Clinically, there are many methods of colon examination. In this paper, a randomized controlled study was conducted on the diagnostic value of fibro-colonoscopy plus barium contrast angiography (ACBE) and colonoscopy for lower gastrointestinal bleeding. Materials and Methods: 322 cases of lower gastrointestinal bleeding ≥40 years were randomly divided into two groups, a group: 164 cases underwent colonoscopy; b group: received fibro-colonoscopy plus ACBE 168 cases. ACBE and fiber B colonoscopy arranged in the same day. Colonoscopy should be inserted into the end of the cephalic colonoscopy, B colonoscopy inserted at least 30cm. Results: 161 patients (96%) underwent fiberoptic colonoscopy were inserted smoothly, with an average insertion depth of 50cm. 31 people (18%) No abnormal hair
