Long-term Outcomes After Prolonged Dual Hypothermic Oxygenated Machine Perfusion of Donor Livers (DHOPEPROLONG)

End-ischemic dual hypothermic oxygenated machine perfusion (DHOPE) of human donor livers mitigates ischemia-reperfusion injury, resulting in a reduction of post-reperfusion syndrome, early allograft dysfunction and biliary complications, when compared with static cold storage. End-ischemic DHOPE can be used to prolong donor liver preservation time for up to 24 hours. According to IDEAL-D (Idea, Development, Exploration, Assessment, Long term study-Framework for Devices), scientific evidence for prolonged DHOPE has currently reached stage 3. Assessment of long-term outcomes after prolonged DHOPE preservation based on real-world data (i.e., IDEAL-D stage 4) is currently still lacking.
