抄録

Recent progress in colonof iberscope has made the possible understanding of the direct observation on the entire colon, following the remarkable improvement on the diagnosis of the lower bowel. In some cases, however, it is difficult to introduce the scope into the right sidded colon because of the extension of the sigmoid colon, which prevents from the sufficient arri-val to the lesion. We deviced a overcoat-tube of the scope for pressing clown the extension of the sigmoid colon. In directly leading the inserting force to its tip, this tube aids the scope in reaching into the caecum with ease and shortly. A "sliding tube" we named, is an elastic tube which is 1.5 and 2.0 cm in an inside and an outside diameter and is 47 cm in length. We have applied the "sliding tube" to 28 cases and obtained some statisf actory results. This paper shows the frame and the method of the tube and the results of the cases we used.
