AIM To characterize major determinants of 20-year survival after liver transplantation(LT).METHODS This longitudinal single-institution study includes 313 consecutive patients who received a LT between 1988 and 1992. Pretransplant clinical characteristics and laboratory values were assessed and compared between 20-year survivors and non-survivors. Particular attention was paid to the Model for End-Stage Liver Disease(labM ELD)-score and the Eurotransplant Donor Risk Index(ET-DRI) to unravel their impact on 20-year survival after LT.RESULTS Twenty-year survivors were significantly younger(44 vs 50 years, P = 0.001), more likely to be female(49% vs 36%, P = 0.03) and less likely to be obese at the time of LT(19% vs 32%, P = 0.011). Mean labM ELD-score(P = 0.156), rate of high-urgency LT(P = 0.210), coldischemia time(P = 0.994), rate of retransplantation(P = 0.12) and average donor age(28 vs 33 years, P = 0.099) were not statistically different. The mean estimated glomerular filtration rate was higher among survivors(P = 0.007). ET-DRI > 1.4(P = 0.020) and donor age ≥ 30 years(P < 0.022) had significant influence on 20-year survival. The overall survival was not significantly impacted by labM ELD-score categories(P = 0.263).CONCLUSION LT offers excellent long-term results in case of optimal donor and recipient conditions. However, mainly due to the current organ shortage, these ideal circumstances are rarely given; thus algorithms for donor-recipient matching need to be refined, in order to enable a maximum benefit for the recipients of high quality as well as marginal organs.
