Incidence of liver retransplantation and its effect on patient survival

The purpose of this study was to review our institutional experience with re-liver transplantation (OLT) after split and full-size OLT.

We evaluated data corresponding to retransplanted patients over an 8-year period who underwent deceased donor OLT at our institution. Variables analyzed included indications for primary OLT, and re-OLT, the type of graft used during the initial versus re-OLT, the time from initial to re-OLT, and patient survival after re-OLT.

Sixty-four of 697 first OLT (9.2%) required re-OLT. Forty-nine cases were among 637 (7.6%) full-size OLT, while 15 were among 60 (25%) split OLT (P < .001). Median time to re-OLT was 8 days (range = 1-1885 days). Main indications for re-OLT were primary nonfunction/initial poor function (44%), hepatic artery thrombosis (26%), biliary complications (11%), and hepatitis C recurrence (6%). Forty-eight percent of the re-OLTs were performed within the first posttransplant week. The overall survival for these 64 patients was 55% and 48% at 1 and 3 years after the primary OLT, and 44% at both 1 and 3 years after the re-OLT, respectively.

The overall incidence of re-OLT remains 9%. Approximately half of all re-OLT occured within the first posttransplant week. Early retransplantation was associated with the best patient survival. Overall survival after re-OLT was about 10% to 20% lower than that after primary OLT.
