Abstract
Precise illustration of the intra hepatic biliary anatomy and anatomical variant is crucial in pre operative assessment of living right liver donors.
Purpose: Is to evaluate the accuracy of Magnetic Reso-nance Cholangiopancreatography (MRCP) in pre operative assessment of biliary system anatomy in living right liver donors compared to Intra Operative Cholangiography (IOC).
Material and Methods: Fifty living liver donors were included in the study underwent MRCP examination. Findings were compared with intraoperative cholangiography. Sensi-tivity, specificity and accuracy were calculated.
Results: MRCP was able to detect anatomical variants in 46 donors. According to Hakki classification; 15 cases (30%) were K1 type, K2a was seen in 9 cases (18%), K2b in 4 cases (8%), K3 a in 15 cases (30%), K4 in 7 cases (14%) with overall sensitivity=88.2%, Specificity=94.2%, Accuracy=92%, PPV=88.2%, NPV=94.5%.
It also detected 5 from 10 small sized segmental accessory intra-hepatic biliary ducts.
Conclusion: MRCP is a valuble tool in pre-operative assessment of the biliary anatomy variants in potential right liver donors.
