*Purpose: A short period (1-2 hours) of hypothermic oxygenated machine perfusion (HOPE) after static cold storage is safe and reduces ischemia-reperfusion injury-related complications after liver transplantation. Machine perfusion time is occasionally prolonged for logistical reasons, but outcomes after prolonged HOPE are currently unknown. The purpose of this study was to investigate if prolonged HOPE is safe and does notcompromise postoperative outcomes.
*Methods: We conducted a multicenter, observational cohort study of patients transplanted with a donor liver preserved by prolonged (≥4 hours) HOPE. Postoperative biochemistry, outcomes, complications, and survival were evaluated.
*Results: The total cohort included 93 recipients of 12 European transplant centers between 2014-2021. The most common reason to extend HOPE was the lack of an available operating room to start the transplant procedure. Grafts underwent HOPE for a median (range) of 4:37h (4:00- 8:15h) with a total preservation time of 10:45h (5:50-20:50h). Postoperative peak ALT was 595 IU/L (interquartile range 372-1214 IU/L). The incidence of postoperative complications was low, and 1-year graft and patient survival were 93%, and 92%, respectively.
*Conclusions: Good outcomes are achieved after transplantation of donor livers preserved with prolonged (≥4 hours) HOPE. These results suggest that simple, end-ischemic HOPE may be utilized for safe extension of the preservation time to ease transplantation logistics.
