Long-term follow-up after full-split liver transplantation and its applicability in the recent transplant era.

INTRODUCTION

Full-split liver transplantation (LTX) offers the possibility to expand the donor pool by utilization of one liver for two adults. The aim of our study was to analyze the long-term outcome in a large series and its applicability in the recent transplant era.

METHODS

We performed a retrospective analysis of all full-split LTX from deceased donors (1999-2015). Additionally, the potential of full-split LTX was retrospectively analyzed in all whole organ LTX recipients between 2006 and 2015 (after introduction of the MELD allocation).

RESULTS

We performed 44 full-split LTX, thereof 82% before introduction of the MELD-based allocation system in Germany. Analysis showed highly selected recipients (median MELD score 8 points) and organ data (median donor age 30 years). 5- and 10-year patient survival rates after full-left and full-right LTX were 90.7%/90.7% and 85.2%/56.8% (P = .301), corresponding graft survival rates were 80.5%/80.5% in full-left grafts and 73.7%/36.8% in full-right graft (P = .198).

CONCLUSION

In the past, in case of strict donor and recipient selection, full-split LTX was a feasible method with a good outcome. Due to introduction of the national waiting list with a patient-oriented allocation based on the MELD score in 2006, full-split LTX seems to be not any longer applicable.
