Background: Recent evidence supports the use of machine perfusion technologies (MP) for marginal liver grafts. Their effect on enhanced recovery, however, remains uncertain. Objectives: To identify areas in which MP might contribute to an ERAS program and to provide expert panel recommendations. Data sources: Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central. Methods: Systematic review and meta‐analysis following PRISMA guidelines and recommendations using the GRADE approach. CRD42021237713 Results: Both hypothermic (HMP) and normothermic (NMP) machine perfusion demonstrated significant benefits in preventing postreperfusion syndrome (PRS) (HMP OR.33,.15‐.75 CI; NMP OR.51,.29‐.90 CI) and early allograft dysfunction (EAD) (HMP OR.51,.35‐.75 CI; NMP OR.66,.45‐.97 CI), while shortening LOS (HMP MD ‐3.9; NMP MD ‐12.41). Only NMP showed a significant decrease in the length of ICU stay (L‐ICU) (MD ‐7.07, ‐8.76; ‐5.38 CI), while only HMP diminishes the likelihood of major complications. Normothermic regional perfusion (NRP) reduces EAD (OR.52,.38–.70 CI) and primary nonfunction (PNF) (OR.51,.27‐.98 CI) without effect on L‐ICU and LOS. Conclusions: The use of HMP decreases PRS and EAD, specifically for marginal grafts. This is supported by a shorter LOS and a lower rate of major postoperative complications (QOE; moderate | Recommendation; Strong). NMP reduces the incidence of PRS and EAD with associated shortening in L‐ICU for both DBD and DCD grafts (QOE; moderate | Recommendation; High) This technology also shortens the length of hospital stay (QOE; low | Recommendation; Strong). NRP decreases the likelihood of EAD (QOE; moderate) and the risk of PNF (QOE; low) when compared to both DBD and SRR‐DCD grafts preserved in SCS. (Recommendation; Strong). [ABSTRACT FROM AUTHOR]
