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

ERCP is a safe and effective treatment for pediatric common bile duct dilatation with stones. Regardless of whether radical surgery was performed or the presence of PBM, patients showed improved laboratory parameters and symptom relief following ERCP. The effectiveness and incidence of adverse events were not related to PBM, but postoperative adverse events were associated with cannulation duration. Beyond its diagnostic utility in CBD and PBM, ERCP serves as a safe bridging therapy prior to radical surgery.
