The significance of image examination in the surgical treatment for congenital choledochal cyst
- Abstract:
- Objetive To evaluate the significance of imaging by magnetic resonance cholangio-pancreatography(MRCP)and by intraoperative cholangiography(IOC)in congenital choledochal cyst. Methods A retrospective study was made on 23 patients,of 2010—2012,with choledochal cysts who were examined by MRCP and IOC accordingly. Results According to Todani’s classification,there were type Ia 12 cases, type Ic 3 cases, and type IVa 8 Cases.The shape of the cyst and the range of the biliary dilation were well illustrated in both MRCP and IOC. The 3D image of MRCP might show the different aspects,so that the stricture could be easily located.The image of the cyst was delineated clearly in IOC,but sometimes, misled by possible overlapping and resulted in oversight. MRCP showed pancreatico biliary maljunction(PBM)in 10 cases(43.5%),while IOC showed PBM in 19 cases(82.6%). The detectability of PBM by IOC was much better than MRCP.All positive findings of biliary strictures were proved and corrected during operation before anastomosis with jejunum. Under the guidence of imaging, the distal end of the cyst was cut close by the pancreatico biliary junction and no injury of pancreatic duct occurred in this study. Conclusion MRCP combined with IOC selectively is,although some invasive,significant in raising the accuracy and confidence in the operation of choledochal cyst.
