Efficacy and Safety of Endoscopic Papillary Balloon Dilation Using Cap-Fitted Forward-Viewing Endoscope in Patients Who Underwent Billroth II Gastrectomy

Abstract Background/Aims: Endoscopic exploration of the common bile duct (CBD) is difficult and dangerous in patients with Billroth II gastrectomy (B-II). Endoscopic papillary balloon dilation (EPBD) via a cap-fitted forward-viewing endoscope has been reported to be an effective and safe procedure. We analyzed the technical success and complications of EPBD in patients who underwent B-II. Methods: Thirty-six consecutive patients with B-II were enrolled from among 2,378 patients who had undergone endoscopic retrograde cholangiopancreatography in a single institute in the last
