Machine perfusion (MP) has been poised to change the face of liver transplant since the first use of hypothermic MP in 2004.1 Since then, innumerable animal models and ex vivo experiments as well as single/multicenter retrospective trials have been published supporting the benefits of MP in liver transplant. The recent multicenter randomized clinical trial (RCT) by Markmann et al2 evaluated the clinical effect of a portable normothermic MP in 300 liver transplants and adds to the 2 other MP RCTs in the literature.3,4 In their study, Markmann et al found that livers that underwent normothermic MP had reduced early allograft dysfunction, decreased histologic evidence of ischemia-reperfusion injury, and decreased ischemic biliary complications at 6 and 12 months relative to controls.2 However, the liver transplant community is still in need of guidance in how to best use this technology.
