Core tip: For patients with a Billroth II gastroenterostomy, endoscopic retrograde cholangiopancreatography (ERCP) is difficult because of altered anatomy, and the success rate decreases for those with Braun anastomosis. ERCP failure in such patients is caused by difficulties in entering the afferent loop and accessing the papilla. We reported the use of a wire-guided retrieval balloon to remove common bile duct stones and facilitate endoscope insertion for successful ERCP in post-gastrointestinal surgery patients. We termed the procedure “retrieval-balloon-assisted enterography”. We believe that retrieval-balloon-assisted enterography along the optimal route may improve the ERCP success rate after Billroth II gastroenterostomy and Braun anastomosis.
