Abstract Background:This study aims to search for new risk factors for biliary complications (BCs) in recipients after living donor liver transplantation (LDLT), focusing on the biliary anatomy of the donor.Methods:The study included 123 patients who underwent donor hepatectomies. Anatomical variations in biliary branching patterns, the maximum bifurcation angle of the left and right hepatic ducts, the rotation axis of the hepatic ducts, the bifurcation position of the hepatic ducts, and the bile duct diameter were evaluated with the occurrence of BCs.Results:BCs occurred in 25 recipients (20.3%), who had a larger bifurcation angle (83.6° vs. 105.9°, p = 0.001) and rotation axis (13.8° vs. 25.6°, p p Conclusions:This study demonstrated a potential association between the biliary anatomy of donors and BCs and suggested the importance of a detailed preoperative evaluation of the donor biliary anatomy.
