Background To assess the diagnostic ability and safety of endoscopic retrograde cholangiopancreatography (ERCP) in in-depth preoperative examination of children patients with pancreaticobiliary maljunction (PBM). Methods In 63 patients with a definite diagnosis of PBM, the ability to visualize the bile and main pancreatic ducts was compared between ERCP, which was performed in 63 patients with a definite diagnosis of PBM, and magnetic resonance cholangiopancreatography (MRCP), which was performed before ERCP in 29 patients. For ERCP, its complications were also evaluated. Results The intrahepatic bile ducts could be visualized using ERCP in 44 patients (69.8%) and using MRCP in 18 (62.1%). The extrahepatic bile ducts could be visualized using ERCP in 59 patients (93.7%) and using MRCP in 29 (100%). The rates of the visualization of the main pancreatic duct and pancreaticobiliary ductal union were significantly higher in using ERCP than in using MRCP (96.8 vs. 41.4% and 90.5 vs. 37.9%, respectively; P < 0.0001). As complications, hyperamylasemia developed in 12 patients (19%), but no other severe complications such as pancreatitis were observed. Conclusions ERCP as part of an in-depth preoperative examination of children with PBM is useful and safe.
