ARTICLE HIGHLIGHTS
Research background
There is no consensus on the usage of extended criteria donor (ECD) grafts in liver transplantation (LT) for acute-on-chronic liver failure (ACLF) patients.
Research motivation
It was intended to summarize the experience of using ECD livers in ACLF-LT.
Research objectives
Our study aimed to summarize the experience of using ECD livers in ACLF-LT, and to provide reference for clinical practice.
Research methods
We conducted a retrospective cohort study to analyze outcomes between ECD and non-ECD recipients.
Research results
There was no significant difference (P > 0.05) in survival between ECD and non-ECD recipients after LT, although ECD grafts were associated with a significantly higher incidence of early allograft dysfunction. The most important factors affecting post-LT survival of ACLF patients were extrahepatic organ failures (OFs) > 2 (P = 0.015) and intraoperative blood loss (P = 0.000).
Research conclusions
ECD grafts can be safely used in ACLF-LT, although related to a higher risk of early allograft dysfunction.
Research perspectives
Due to the unavoidable selection bias in clinical practice, there were only 2 cases of donor liver have diagnosed as macrovesicular steatosis more than 30%. This indicates that the ECD grafts actually adopted in our clinical practice may be relatively safe, and those grafts empirically judged as "high risk" were abandoned. Admittedly, this is a major limitation of our current study, and the next step will be to try to compensate it by including more cases in our study over a longer period or in conjunction with other transplant centers.
