Existing guidelines for the management of choledocholithiasis in adults may not be applicable in children, given anatomic differences and the limited availability of ERCP in many pediatric centers.  This retrospective study seeks to develop a diagnostic and treatment algorithm for choledocholithiasis in children that minims unnecessary interventions and optimized clinical outcomes.  In addition, the study aims to determine the role of MRCP and ERCP in the diagnosis and management of gallstone disease in children.
