The liver transplantation unit from Córdoba, Spain, performed its first liver transplantation in 1989. Since then, 500 liver transplants have been performed in our institution up to November 2001. Our one-year recipient and graft survival rates are 77% and 76%, respectively. These recipient and graft survival rates are lower when compared with other results in the English language literature, and we present evidence here that the disparity results from 4 especially problematic aspects of our program: 1) the expanded use of donors, 2) the policy of allocation and prioritization in our institution, 3) the recurrence of primary liver disease and 4) de-novo neoplasms. Liver transplantation with unstable, hypernatremic donors or donors with a lengthy hospitalization and grafts with a prolonged cold ischemia time leads to diminished graft survival. When several marginal criteria accumulate in a donor, the results are even poorer. Consequently, the delayed non-function rate is especially high in our series. Attention to severe liver preservation injury as a primary mechanism of graft losses with marginal donors is given. The impact of the policy of the "sickest-first" principle in our center with a long waiting list seems to benefit urgent but not elective patients. Survival in elective patients is poorer than expected considering their clinical condition. The use of the sickest-first or urgency principle in our unit has not been efficient or equitable and may partially explain the poorer survival of our patients. Finally, the recurrence of primary disease and incidence of de-novo tumors after transplantation in our unit are similar those reported in English language literature.
