Update on pediatric liver transplantation in Europe 2022: An ELITA-ESPGHAN report.

OBJECTIVES

The European Liver Transplant Registry (ELTR) has been collecting data on liver transplantation (LT) in Europe since 1968. The aim of this report is to outline the number, techniques utilized, indications for, and outcomes of pediatric LT (pLT) in Europe, focusing on the Year 2022 in comparison to the preceding 5 years.

METHODS

Data were obtained from ELTR and Eurotransplant (ET). Summary statistics were performed.

RESULTS

In 2022, 585 pLTs were performed in Europe. The annual number of pLT decreased for the third consecutive year. Living donor LT represented 34% (n = 201) of pLT. The proportion of living donation (LD) remained stable over time. The major indication for pLT in Europe is biliary atresia. Donor age is increasing overall and is associated with worse graft survival. Graft and patient survival were impacted by both types of donors and types of grafts, and were significantly worse after re-transplantation. Most graft failures (77%) and deaths (82%) occurred within the first 6 months after pLT.

CONCLUSION

Annual numbers of pLT in Europe are decreasing over time. Given that the proportion of LD has remained stable, the shortage of deceased donor organs may not be the major reason for this trend, and other factors play a role. A focus on improving perioperative care is needed because the risk of graft loss and mortality is highest in the first 6 months after transplantation. New techniques like ex-situ machine perfusion may help mitigate risks with declining quality of deceased donor liver grafts.
