The usefulness of a novel sphincterotome with smooth rotatability for selective guidewire insertion Video 1 A novel sphincterotome that can undergo smooth rotation and subtle adjustment was useful for selective guidewire insertion. Fig. 1 The novel sphincterotome (Engetsu; Kaneka Medics, Osaka, Japan) can undergo smooth rotation and subtle adjustment. Fig. 2 Computed tomography and magnetic resonance cholangiopancreatography showed distal biliary obstruction (blue arrowheads).
