Efficacy and Safety of a Novel Rotatable Sphincterotome for Endoscopic Sphincterotomy in Patients With Roux-en-Y Gastrectomy During Balloon Enteroscopy-Assisted ERCP (With Video).

ABSTRACT: Endoscopic sphincterotomy (EST) is challenging for patients with surgically altered anatomy (SAA). The blades of conventional sphincterotomes designed for SAA do not always face the correct direction of EST. We aimed to evaluate the efficacy and safety of a novel rotatable sphincterotome for EST in patients undergoing Roux-en-Y gastrectomy during balloon enteroscopy-assisted endoscopic retrograde cholangiopancreatography (BE-ERCP). Patients with Roux-en-Y gastrectomy who underwent BE-ERCP and EST using a novel rotatable sphincterotome between April 2024 and February 2025 were analyzed. Overall, 30 patients were attempted EST with a novel rotatable sphincterotome. EST, including adjustment of the blade to the correct incision direction, was successfully performed in all patients.
