Impact of periampullary diverticulum on endoscopic retrograde cholangiopancreatography: bridging the gap between fiction and reality

Abstract Introduction: Periampullary diverticulum (PAD) is frequently discovered in patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Studies have yielded conflicting results regarding its impact on the technical success of ERCP and post-ERCP complications. Aim: This study aims to assess the success and safety of ERCP in patients with PAD. Material and methods: This study included 400 patients who underwent ERCP for common bile duct (CBD) stones. Patients were classified into the PAD group (200 patients) and the non-PAD group (200 patients).
