Working up donors for high-urgency and elective adult-to-adult live donor liver transplantation

Abstract

Donor workup for adult-to-adult live donor liver transplantation is done to ensure that the donor remains physically and psychologically healthy after saving or improving the life of the recipient. Even though two-thirds of the liver transplants in our center were from live donors, this life-saving procedure remains a mere treatment option, given the magnitude of the donor operation with the associated donor risks. Live donor liver transplantation was also adopted for high-urgency situations provided that the donor was suitable and the recipient considered salvageable. Donor workup in this setting had not been reported in the literature. In this cohort of 399 potential donors, 128 (32.1 %) ultimately underwent donor surgery. Donors in the high-urgency situation had a lower operation rate of 28.4% (64/225) compared with that of 36.8% (64/174) of donors in the elective situation (P = 0.049). Dropouts from step 1 mainly because of ABO incompatibility, positive hepatitis serology, comorbidities, and voluntary donor withdrawal were 52.6% (210/399). Only 11.6% (22/189) of the potential donors who proceeded to subsequent steps of the workup dropped out (2 were psychologically unsuitable, 10 were anatomically prohibitive). The transplantation rate of potential recipients with 1 or more potential donors was also high. The rates were similar for the high-urgency (55%, 64/116) and the elective (51%, 64/125) situations. In a region with scarcity of deceased donor liver grafts, careful and expeditious initial donor workup minimizes dropWts from subsequent steps and allows timely transplantation in high-urgency situation. © 2007 AASLD.
