Background: Biliary complications in donor hepatectomies are still common, and occur in approximately 5% of the procedures. Study Design: To evaluate the usefulness of the management and surgical procedures to prevent the biliary complications in donor hepatectomies, a total of 343 donors were retrospectively studied. The clinical and surgical parameters of the donors and the postoperative biliary complications were evaluated. Results: Fourteen donors had biliary complication (BC) during the follow-up period (4.1%). Donors were divided into 2 groups; donors without BC (non-BC group; n = 329) and donors with BC (BC group; n = 14). Mean peak level of total bilirubin, mean duration of hospital stay after surgery, and medical cost in the BC group were significantly higher than in the non-BC group (p < 0.01). As improved procedures to prevent the BC were established at 2005, including the use of a real-time cholangiography by the C-arm, a minimized dissection of the hepatic vessels, the meticulous closure of the bile duct, and/or the use of Pringle maneuver during the parenchymal transection, the donors were divided into 2 groups before and after these establishments (the early period, n = 173; the later period, n = 170). Refinements in the management and surgical procedures reduced the occurrence of biliary complications from 6.4% during the early period to 1.8% during the later period (p < 0.01), and no biliary complications in the last 69 consecutive donors were observed. Conclusions: Technical refinements described in this study might be useful to prevent the occurrence of biliary complications in a donor hepatectomy. It is particularly important to preserve the blood supply for the biliary tract of both the graft and the remnant liver.
