Abstract
OBJECTIVE: Roles of magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), drip infusion cholangiography with computed tomography (DIC-CT), and intraoperative cholangiopancreatography (IOCP) in visualizing pancreaticobiliary anatomy for pediatric choledocal cyst (CC) operations were examined. METHODS: From 1980-2013, 117 pediatric CC patients (median age, 3 years) underwent hepaticojejunostomy at our institution, with imaging modalities of ERCP (n = 81 over 34 years), MRCP, DIC-CT, and IOCP (n = 45, 20, and 45 cases over the last 12 years). First, visualization rates for pancreaticobiliary maljunction (PBM), common bile duct (CBD), pancreatic duct (PD), and intrahepatic bile duct (IHBD) were investigated. Sensitivity, specificity, and accuracy for detecting hepatic duct stricture were then compared between MRCP and IOCP. RESULT: Visualization rates of PBM, CBD, PD, and IHBD were 57%, 100%, 64%, and 100% for MRCP; 82%, 77%, 95%, and 32% for ERCP; 25%, 75%, 21%, and 85% for DIC-CT; and 87%, 100%, 87%, and 100% for IOCP, respectively. Combination of MRCP and IOCP achieved rates of 89%, 100%, 91%, and 100%, respectively. Sensitivity, specificity, and accuracy for detecting stenosis were 86%, 68%, and 71% for MRCP, and 100%, 89%, and 91% for IOCP, respectively. CONCLUSIONS: Combining MRCP and IOCP can provide satisfactory pancreaticobiliary anatomical information for surgical planning for pediatric CC, with hepatic duct strictures evaluated more accurately by IOCP.
