Analysis of Indications and Results in Liver Retransplantation: Is Late Retransplantation Worthwhile?

Liver retransplantation (LrT) is the only therapeutic option for irreversible hepatic graft failure. Despite various improvements, its technical complexity entails a greater morbidity in the short and long term. The main goal of the study was to analyze the activity of LrT at our center, as well as its indications, timing, postoperative evolution, and the long-term survival of patients.

We designed a descriptive study of a cohort of patients who underwent LrT in a Spanish Hepatic Transplant Unit, between April 1, 2002 and December 31, 2015.

A total of 366 primary orthotopic liver transplantations were performed, 20 of which were LrTs, resulting in a 5.5% retransplantation rate. The most frequent indication for LrT was hepatic artery thrombosis (HAT) (35%). Twenty-five percent of the LrTs were early retransplantations and 75% were late retransplantations. After LrT, 35% of the grafts showed liver dysfunction. The overall mortality rate was 45%: in early LrT this was 25% and in late LrT it was 46.7%. Graft actuarial survival at 1 month post-LrT was 75% and at 5 years it was 63.6%. The overall actuarial survival after LrT at month 1, year 1, year 3, and year 5 was 80%, 69.6%, 58.9%, and 50.5%, respectively. In the late LrT group, the results proved less favorable, so it is necessary to define the minimum acceptable result before proceeding to a second graft.

Our LrT rate was lower than that reported by other groups in our country. The actuarial survival rates for graft and patient are comparable to those obtained by other groups.
