Endoscopic retrograde cholangiopancreatography for the treatment of common bile duct dilatation with choledocholithiasis in children: a single-center retrospective cohort study of 58 cases

Abstract Background: Congenital biliary dilatation (CBD) represents a prevalent congenital anomaly in pediatric surgery, with concurrent choledocholithiasis observed in a notable subset of pediatric patients. Improper management of such cases can compromise early diagnosis of CBD and adversely impact outcomes of radical surgery. This retrospective study evaluated the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) in pediatric patients with common bile duct dilatation complicated by choledocholithiasis, aiming to refine clinical strategies for diagnosis and preoperative management to mitigate long-term
