Common bile duct morphology is associated with recurrence of common bile duct stones in Billroth II anatomy patients

Abstract BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) is the primary choice for removing common bile duct (CBD) stones in Billroth II anatomy patients. The recurrence of CBD stones is still a challenging problem. AIM: To evaluate CBD morphology and other predictors affecting CBD stone recurrence. METHODS: A retrospective case-control analysis was performed on 138 CBD stones patients with a history of Billroth II gastrectomy, who underwent therapeutic ERCP for stone extraction at our center from January 2011 to October 2020.
