Endoscopic Papillary Large Balloon Dilation for the Retrieval of Bile Duct Stones After Prior Billroth II Gastrectomy

Abstract Background/Aims: Endoscopic retrieval of large common bile duct (CBD) stones is often difficult in patients who have undergone Billroth II gastrectomy, as anatomic alterations may present technical barriers to successful cannulation and increase procedure-related complications. Endoscopic papillary large balloon dilation (EPLBD) can be an alternative technique for the removal of difficult stones. Accordingly, the aim of this study was to evaluate the safety and effectiveness of EPLBD for CBD stone extraction in patients with Billroth II gastrectomy. Materials and
