Endoscopic Retrograde Cholangiopancreatography with Balloon-Assisted Enteroscope in Patients with Surgically Altered Upper GI Anatomy

AbstractEndoscopic retrograde cholangiopancreatography (ERCP) is technically more challenging in patients with postsurgical anatomy such as Billroth II anastomosis and Roux-en-Y anastomosis, frequently mandating an operative intervention. Currently, ERCP using balloon-assisted enteroscopy (BAE) has become the main approach in patients with complex postoperative anatomy. This article presents the technical aspects of performing ERCP with BAE in patients presenting with complex postsurgical anatomy having biliary problems. ERCP using BAE is feasible in patients with complex postsurgical anatomy, permitting diagnostic and therapeutic interventions in 80% of patients. This article is part of an expert video encyclopedia
