Marginal donors for patients on regular waiting lists for liver transplantation.

The use of marginal donors is well accepted by most centers for emergency situations, but there is debate on their use for patients on regular waiting lists. We report our experience of the 1-year survival for patients on waiting lists (n = 147, 1-year survival = 32%), patients transplanted from good donors (n = 60, 1-year survival = 84%), and patients transplanted from marginal donors (n = 15, 1-year survival = 56%). We concluded that liver transplantation from marginal donors (a) is a safe procedure (b) has a 1-year survival that is significantly better than that on a waiting list (c) is ethically justified especially in countries with donor shortages, and (d) may allow transplantation of "special" high risk and poor long-term outcome patients.
