Liver retransplants using living donors:An approach for management

Background and aims:Many centers do not offer living donor transplants for patients in need of a liver retransplant.We aimed to study our liver retransplant outcomes using living donors and compared them with those of retransplants performed using deceased donors.Methods:This study retrospectively analyzed all retransplants performed at our center between 2009 and 2023,and outcomes of living donor retransplants were compared with deceased donor retransplants using standard statistical tests.Results:Between January 2009 and March 2023,a total of 77 retransplants,60 with deceased donors and 17 with living donors,were performed.Important demographic differences between the two groups included a higher model for end-stage liver disease score in the deceased donor group(32.1±6.1 vs.19.4±5.7,P<0.001)and a higher number of early retransplants(within 3 months of the initial transplant),which accounted for 35% of deceased donor transplants but 0 of living donor transplants(P<0.01).Overall,the patient and graft survival rates were comparable between the two groups.The patient survival rates at 1 and 3 years after transplant were 73% and 67% in the deceased donor group and 84% and 73% in the living donor group,respectively(P=0.57).The hospital length of stay and blood product use were both better in the living donor group.Biliary complications did not show significant different between the two groups(P=0.33).Conclusions:Living donors can provide acceptable outcomes for those in need of a retransplant,with results comparable to those seen with deceased donors.A systematic approach to the patient in the pre-,peri-,and post-transplantation period is important in these complicated cases.
