抄録

ERCP with a side view duodenofiberscope JF-B2 was performed to a 53-year old male who had a previous history of Gastrectomy of Billroth II type, revealing cholecystocholedocholithiasis.At the first time, endoscopic papillotomy was carried out with a front view fiberscope GIF-P2 and a stone in the bile duct was removed. After confirming the removal of the stone in the bile duct, cholecystectomy was performed. Both Sohma type and Ikeda-Classen type cutting knives were used in this case. A slender front view fiberscope GIF-P2 is useful for ERCP or EPT for Billroth II gastrectomized cases.
