Endoscopic ostium incision at non-malignant post-surgical bilioenteric anastomotic stricture after complex abdominal surgery

Background and aims: Bilioenteric anastomotic stricture is a well-known complication after bile duct surgery or liver transplantation. This study reports our experience with endoscopic ostium incision of high-grade or subtotal stricture at the non-malignant biliary enteroanastomosis. Patients: Over a 7-yr period among more than 7500 ERCPs, 38 patients (0.50%) after complex abdominal surgery were identified with high-grade/subtotal bilioenteric anastomotic stricture with failed cannulation or inaccessible ostium. Interventions: DBE enteroscopy (n = 19), push enteroscopy (n = 7) or transstomal endoscopy via jejuno…
