Ischaemic preconditioning of the graft in adult living related right lobe liver transplantation: impact on ischaemia-reperfusion injury and clinical relevance.

Abstract

BACKGROUND Ischaemic preconditioning (IPC) of the right liver graft in the donor has not been studied in adult-to-adult living related liver transplantation (LRLT). OBJECTIVE To assess the IPC effect of the graft on ischaemia reperfusion injury in the recipient and compare recipient and donor outcomes with and without preconditioned grafts. PATIENTS AND METHODS Alternate patients were transplanted with right lobe grafts that were (n = 22; Group (Precond)) or were not (n = 22; Group (Control)) subjected to IPC in the living donor. Liver ischaemia-reperfusion injury, liver/kidney function, morbidity/mortality rates and outcomes were compared. Univariate and multivariate analyses were performed to identify factors predictive of the aspartate aminotransferase (AST) peak and minimum prothrombin time. RESULTS Both groups had similar length of hospital stay, morbidity/mortality, primary non-function and acute rejection rates. Post-operative AST (P = 0.8) and alanine aminotransferase (ALT) peaks (P = 0.6) were similar in both groups (307 +/- 189 and 437 +/- 302 vs. 290 +/- 146 and 496 +/- 343, respectively). In univariate analysis, only pre-operative AST and warm ischemia time (WIT) were significantly associated with post-operative AST peak (in recipients). In multivariate analysis, the graft/recipient weight ratio (P = 0.003) and pre-operative bilirubin concentration (P = 0.004) were significantly predictive of minimum prothrombin time post-transplantation. CONCLUSIONS Graft IPC in the living related donor is not associated with any benefit for the recipient or the donor and its clinical value remains uncertain.
