CLINICAL EXPERIENCE WITH ENDOSCOPIC PAPILLOTOMY BY USING THE IMPROVED PUSHING-TYPE-PAPILLOTOME (SECOND REPORT)

Abstract

There are several types of papillotome, but they are not always satisfactory for use. Therefore we devised an improved pushing-type-papillotome in November 1979 and reported it's structure and characteristics. Some advantages of the improved papillotome were as follows, (1) durability is stronger than ordinary ones, (2) well suited for pushing incision under duodenoscopic stretching approach, (3) suited for fine incision i, e. in cases with an juxtapapillary diverticulum or in cases with reincision, (4) can prevent serious complications due to it's fine incision. In Sakura National Hospital, endoscopic papillotomy was carried out on 43 patients with choledochlithiasis or benign papillary stricture by using the improved pushing-typepapillotome, from November 1979 to December 1983 and was successful in 40 cases (93%) without serious complications.
