Role of pediatric endoscopic retrograde cholangiopancreatography in an era stressing less-invasive imaging modalities.

Background: The significance of pediatric endoscopic retrograde cholangiopancreatography (ERCP) according to age or disease variation is inconclusive. This study aimed to evaluate the usefulness of pediatric ERCP in diagnosing or treating small children with pancreaticobiliary disorders, including choledochal cyst (CC) and biliary atresia (BA).

Methods: From 1980 to 2011, 235 ERCPs were performed in 220 pediatric patients (median age, 2 years) at our institution.
