The European Liver Transplant Registry (ELTR) has collected data on liver transplant procedures performed in Europe since 1968. Over a 50 years period (1968 - 2017), clinical and laboratory data were collected from 133 transplant centers and analyzed retrospectively (16,641 liver transplants in 14,515 children). Data were analyzed according to 3 successive periods (A: before 2000, B: 2000 to 2009, and C: since 2010), studying donor and graft characteristics, and graft outcome. The use of living donors steadily increased from A to C [A: n=296 (7%), B: n=1131 (23%) and C: n=1985 (39%); P=0.0001]. Overall, the 5-year graft survival rate has improved from 65% in group A to 75% in group B (p<0.0001), and to 79% in group C (B vs C, p<0.0001). Graft half-life was 31 years, overall; it was 41 years for children who survived the first year after transplant. The late annual graft loss rate in teen-agers is higher than children aged < 12 years, and similar to that of young adults. No evidence for accelerated graft loss after age 18 year was found. Pediatric liver transplantation has reached a high efficacy as a cure, or treatment, for severe liver disease in infants and children. Grafts that survived the first year had a half-life time similar to standard human half-life. Transplantation before or after puberty may be the pivot-point for lower long-term outcome in children. Further studies are necessary to re-visit some old concepts regarding transplant benefit (survival time) for small children, the role of recipient pathophysiology versus graft aging, and risk at transition to adult age.
