Background: The history of end-stage liver diseases has been changed by liver transplantation. Egypt’s high prevalence rate of liver diseases has increased the number of patients requiring liver transplantation. Living donor liver transplantation has many advantages over deceased donor liver transplantation; nevertheless, biliary complications, which are the commonest intractable problem, are more likely to occur after living donor liver transplantation. Magnetic Resonance Cholangiography is a non-invasive method to assess the biliary system’s anatomy.
Objective: In this study, we aimed to assess the anatomic variations of the biliary tree among the Egyptian population using Magnetic Resonance Cholangiography.
Patients and Methods: We conducted this study on 353 patients who underwent MRC procedures between May 2010 and December 2015. Anatomical variations of intrahepatic bile ducts were studied based on the variable insertion of the right posterior hepatic duct according to Huang classification; moreover, the presence of accessory ducts was also noted.
Results: Based on the Huang classification, variations were divided into five types.Type 1 (typical type) occurred in 207 cases (58.6%) while type 2 (triple confluence) occurred in 61 cases (17.3%). Type 3, Type 4, and Type 5 were noted in 66 cases (18.7%), 14 cases (4%), and 5 cases (1.4%). We observed accessory duct in 14 cases (4%of all studied cases).
Conclusions: Our findings provide a precise understanding of the variations of the intrahepatic bile ducts among Egyptians. This is important for both donors and recipients to ensure a successful liver transplant and reduce subsequent biliary complications.
