Abstract

Purpose: Normothermic machine-based liver perfusion (NMP) has demonstrated improved outcomes versus cold ischemic storage in liver-alone transplantation. Methods: This study includes adult liver-alone transplantation recipients at our center from 1/16/2016 to 7/1/2022. Liver transplantation delivered on pump were identified with retrospective chart review. 1-to-2 propensity score matched models adjusting for donor and recipient characteristics were fitted to estimate the treatment effect of NMP on post-reperfusion syndrome, index hospital length of stay (LOS), 3-month biliary complications, biopsy proven rejection, graft survival, and patient survival compared to conventional ischemic cold storage. Results: 593 liver transplantations were included with 42 delivered on NMP. The NMP group had higher DCD liver transplantation (35.7% vs 17.4%, P=0.001), fewer reoperations (9.1% vs. 19.2%, P=0.04), trend towards shorter LOS (9 [IQR: 7-16] vs 10 [IQR:7-18] days, P=0.42), trend towards less post-reperfusion syndrome (11.3% vs 20%, P=0.06). On propensity score matched analysis, OCS livers had non-inferior 3-month biliary complications (HR = 1.34, P = 0.78, [95% C.I. = 0.47-2.78]), biopsy proven rejection (HR = 1.58, P = 0.77, [95% C.I. = 0.49-5.15]), graft failure (HR = 0.42, P = 0.78, [95% C.I. = 0.56-2.62]), and patient death (HR = 0.39, P = 0.66, [95% C.I. = 0.30-2.81]). Conclusions: The use of NMP in liver-alone transplantation in our center is associated with significantly higher proportion of DCD liver transplantation and fewer reoperations, trend towards shorter LOS and post-reperfusion syndrome, as well as non-inferior 3-month biliary complications, graft survival, and patient survival compared to livers delivered on conventional cold ischemic storage.
