BackgroundDonor shortage is the biggest obstacle in organ transplantation. Living donor liver transplantation (LDLT) has been considered as a valuable approach to shortening waiting time. The objectives of this study were to investigate the feasibility of utilizing donors older than 50 years in LDLT and to evaluate the graft function and recipient survival.MethodsAll LDLT cases (n=159) were divided into the older (donor age≥50 years, n=10) and younger (donor age<50 years, n=149) donor groups. Donor graft and recipient condition pre-, intra- and post-operation were compared between the two groups. In particular, graft functions and recipient survivals were analyzed.ResultsThe median donor age was 58.5 (52.5-60.0) years in the older donor group and 25.0 (23.0-32.0) in the younger donor group. There was no significant difference in cold ischemic time, anhepatic phase and operation time between the older and younger donor groups (P>0.05). However, the volume of red blood cell transfused in operation was greater in the older donor group than in the younger donor group (1900 vs 1200 mL, P=0.023). The 1-, 3- and 5-year graft survival rates were 90%, 80% and 80% for the older donor group, and 92%, 87% and 87% for the younger donor group, respectively (P=0.459). The 1-, 3- and 5-year survival rates were 100%, 90% and 90% for recipients with older grafts, and 93%, 87% and 87% for those with younger grafts, respectively (P=0.811).ConclusionIt is safe for a LDLT recipient to receive liver from donors older than 50 years, and there is no significant adverse effect on graft function and long-term patients' survival.
