近年来纤维结肠镜已发展成为常规检查方法,可检查整个结肠,甚至末端回肠20～50cm,其对结肠病变的诊断正确率高,且可进行活检,也可同时进行息肉电凝套圈摘除等,故我院已将纤维结肠镜检查作为结肠病变主要的检查方法。纤维乙状结肠镜:纤维结肠镜最适宜的长度为130～140cm,更长的结肠镜(160～180cm)使用不便、无任何优点。短的纤维乙状结肠镜(60～65cm)易于使用,但是否能完全代替硬的乙肠镜仍有争论。纤维
In recent years, colonoscopy has developed into a routine examination method. It can inspect the entire colon, and even the terminal ileum is 20 to 50 cm. It has high diagnostic accuracy for colon lesions, and can be used for biopsy. It can also be used for polyelectrocoagulation and ferrule removal. Therefore, our hospital has used fiber colonoscopy as the main method of examination of colon lesions. Fiber sigmoidoscopy: The most suitable length of the colonoscopy is 130 to 140 cm. The longer colonoscope (160 to 180 cm) is inconvenient to use and has no advantages. The short fibrous sigmoidoscope (60-65 cm) is easy to use, but it is still controversial whether it can completely replace the hard ileoscope. fiber
