Introduction: The liver retransplantation rate in Spain is about 6%. The main causes are primary nonfunction, vascular complications, chronic rejection, and recurrent liver disease. The results of this procedure are worse than those of first transplantations.
Patients and methods: This retrospective study evaluated our experience with 54 retransplantations performed between January 1992 and December 2006, which were 5.6% of the 960 orthotopic liver transplantations (OLT) during this period.
Results: In this study, 34.7% of the retransplantations were performed between 4 and 30 days after the first transplantation; another 34.7% were within 1 year. Also, 48.9% of the retransplantations were performed in urgent situations. The main causes for retransplantation during the first month were primary hepatic failure (n = 14) and vascular complications (n = 4). After the first month the main causes were chronic rejection (n = 9), recurrence of hepatic disease (n = 3), and biliary complications (n = 4). Postoperative mortality was 23.9% and morbidity was 76.3%. However, 21.2% of the patients needed a third transplant. The overall rate of patient survival was 60.4% (n = 32) and of graft survival was 56.6% (n = 30). The 5-year actuarial graft survival rate was 65.4% with a mean survival time of 89.84 +/- 8.72 months; the 5-year patient survival rate was 64% with a mean survival time of 114.7 +/- 12.53 months. Worse survival was observed in chronic rejection and in retransplantations performed between 31 and 360 days.
Conclusions: Liver retransplantation presents greater surgical complexity than the first transplantation, but is a good option for patients with failure of the first graft with a 5-year patient and graft survival rate greater than 65%.
