Study summary

Utilisation of extended criteria donors due to critical organ shortage contributes to increased ischemia reperfusion injury as well as mortality following liver transplantation. Experimental data show protective effects on hepatic ischemia reperfusion injury (IRI) using the calcineurin inhibitor Tacrolimus applied intravenously or directly as a hepatic rinse. Moreover clinical data indicate a protective role of a Tacrolimus rinse in human liver transplantation when using normal, healthy grafts. The effects of Tacrolimus on hepatic injury in extended donor criteria (EDC) liver grafts remain unclear. Therefore, the aim of the present study is to examine the effects of a Tacrolimus ex vivo rinse (20 ng/ml) on cellular injury after transplantation of marginal liver grafts exhibiting 2 or more EDCs according to Eurotransplant's definition of EDC grafts.
