    ObjectiveThis study aimed to assess short-term biliary outcomes in adult living donor liver transplants using right grafts, comparing robotic surgery with real-time indocyanine green fluorescence cholangiography for optimal hilar plate transection, against the conventional open approach.BackgroundDetermining the optimal transection plane through the hilar plate is crucial in donor hepatectomies, impacting outcomes significantly.MethodsFrom 2011 to 2023, a total of 839 right graft living donor hepatectomies were performed, with 414 (49%) performed via the open approach and 425 (51%) utilizing the robotic platform.ResultsThe magnetic resonant cholangiopancreatography predictions correlated moderately with the actual count of graft ducts ( r =0.57, P <0.001). Out of all 839 right donor hepatectomies, 321 (44%) were single duct grafts, of which 193/425 (49%) were retrieved with the robotic while 128/414 (38%) were with the open approach (OR: 1.58, 95% CI: 1.16-2.14), P =0.003). Overall, 50 (6%) of the donors developed a biliary complication during their hospital stay, of whom 38 (9%) were grafts retrieved with the open, while 13 (3%) with the robotic approach (OR: 0.31, 95% CI: 0.15-0.61, P <0.001). Similarly, 63 (15%) of the adult recipients developed a biliary complication of any severity when grafts were retrieved with the open approach compared to 35 (8%) with the robotic approach (OR: 0.50, 95% CI: 0.31-0.79), P =0.002).ConclusionsThe robotic platform with integrated real-time indocyanine green fluorescence cholangiography during right donor hepatectomy offers improved safety for the donor by accurately addressing the right hilar corridor, resulting in fewer graft ducts and fewer complications for the donor and recipient when compared to the standard open approach.Copyright © 2024 Wolters Kluwer Health, Inc.
