Usefulness of Magnetic Resonance Cholangiopancreatography and Intraoperative Cholangiography in Detection of Biliary Variants in Children with Choledochal Cysts

SJ Huang, JF Tou, ZG Gao, WG Liu, ZY Zhao


Abstract

Background: Paediatric choledochal cyst (CC) is mainly diagnosed and evaluated by magnetic resonance cholangiopancreatography (MRCP). Although visualisation of CC, biliary stenosis, and pancreaticobiliary maljunction (PBM) is valuable for preoperative diagnosis, it is not enough for making a meticulous surgical plan in consideration of biliary variants. Therefore we aim to evaluate biliary variants as well as CC, biliary stenosis, and PBM by MRCP in children with CC, and to share our experience in managing children with CC using MRCP and intraoperative cholangiography (IOC). Methods: Totally 39 patients with CC who consecutively underwent MRCP, IOC, and radical operation between February 2008 and December 2010 were enrolled in this study. The visualisation rates of CC, biliary stenosis, biliary variants and PBM were compared between by means of MRCP and IOC. The duration of IOC examination was evaluated. Results: The duration of IOC was 23±3 min for all the 39 patients. The visualisation rates of CC, biliary stenosis, biliary variants and PBM were 100%, 79.5%, 46.2%, and 61.5% respectively by MRCP and 100%, 48.5% (p=0.012), 15.3% (p=0.003), and 74.4% (p=0.832) respectively by IOC. Conclusions: Nearly half of the CC patients were accompanied with biliary variants, which should be paid more attention to make a meticulous surgical plan. MRCP was superior to IOC in detecting biliary stenosis and biliary variants, but they are comparable in detecting CC and PBM.
