Grafts from selected deceased donors over 80 years old can safely expand the number of liver transplants: A systematic review and meta-analysis

AIM

The aim of this systematic review and meta-analysis was to present the outcome of deceased adult liver transplantation from octogenarian (≥80 years old) donors compared to younger grafts.

METHODS

A systematic search was performed on six databases to identify all available original papers that report the outcome of adult recipients who underwent liver transplantation from a deceased octogenarian donor.

RESULTS

Overall, 39,034 liver transplantations from 12 studies were reported with 789 (2.02%) cases receiving grafts from octogenarian donors. Eight studies were included in the meta-analysis. There was no difference regarding the one, three, and five-year graft and patient survival between the recipients of livers <80 years old and octogenarian grafts. There were significantly more episodes of biliary complications in the recipients of octogenarian grafts (34/459; 7.4%) in comparison to the recipients of livers <80 years old (372/37074; 1.0%) (OR 0.53; 95% CI = 0.35-0.81; P 0.004; I² = 0%). The incidence of primary non-function, vascular complications and re-transplantation did not differ between groups.

CONCLUSIONS

The short- and medium-term graft and patient survival of octogenarian liver transplantation is not inferior compared to the liver transplantation with younger grafts, however with a higher rate of biliary complications.

Orthotopic Liver Transplantation With Elderly Donors (Over 80 Years of Age): A Prospective Evaluation

BACKGROUND

Our main objective was to assess the clinical outcomes obtained in a single orthotopic liver transplant (OLT) hospital with donors ≥80 years of age compared to a control group of patients subjected to OLT during the same period of time with donors who were under 65 years of age.

METHODS

A prospective analysis was carried out on all the OLTs performed using liver grafts from donors in a state of brain death and with an age of ≥80 years (study group) between April 2007 and January 2015. The results of the study group (n = 36) were compared with those of a control group of patients less than 65 years of age receiving transplants with grafts.

RESULTS

A total of 51 potential donors ≥80 years were assessed, with a total of 36 liver transplants being carried out and their results were compared with a control group of 283 patients receiving transplants. The median follow-up time of the patients in the series was 36 months (range: 24-120 months). Graft survival at 1, 2, and 3 years was 77%, 72%, and 62%, respectively, among the patients in the study group and 79%, 73%, and 65% among the patients in the control group, and there were no statistically significant differences. Patient survival at 1, 2, and 3 years was 86%, 82%, and 75%, respectively, among the patients in the study group and 82%, 76%, and 72% among the patients in the control group, also without there being any statistically significant differences.

CONCLUSIONS

There is no age limit for liver transplant donors. The use of octogenarian donors makes it possible to increase the pool of donors while providing enough safety for the recipient.
