The Effect of Early Retransplantation on Early and Late Survival After Liver Transplantation.

BACKGROUND

Early liver retransplantation after liver transplantation (LT) is the ultimate salvage procedure for irreversible graft failure. The aim of this study was to assess the impact of early retransplantation on 90-day and 5-year patient survival.

METHODS

This retrospective cohort study included 2185 patients after LT in the period between 1997 and 2019. First, the patients undergoing first retransplantation within 6 months after initial LT were compared with naïve LT patients for early mortality (within 90 days). Second, to assess late survival, the patients who had retransplantation and survived at least 90 days post LT were compared with naïve LT patients for 5-year overall survival. The patients undergoing late retransplantation (>6 months) were excluded from analyses. Fisher's exact test was used to compare groups for early survival and log-rank test for late survival.

RESULTS

The cumulative 1-, 3-, and 5-year overall survival was 87.0%, 79.9%, 75.0%, respectively, and did not differ significantly between the groups. The patients undergoing early retransplantation had lower 90-day survival rate of 89.2% as compared to 95.7% for naïve LT patients (P < .001).

CONCLUSIONS

The early liver retransplantation has profound impact on post-LT 90-day survival; however, patients who survive that period can achieve long overall survival comparable with naïve LT patients.
