Introduction:
There have been remarkable efforts to characterize the key responsible pathophysiologic mechanisms, as well as to ameliorate the organ preservation and ischemia reperfusion injury with the ultimate goal of expanding the donor pool and further improvement of the outcomes of liver transplantation. Attempts to translate the experimental results from bench to bedside have yielded no valid protective concepts in the field of clinical liver transplantation yet. Nonetheless, there has been a considerable amount of ongoing clinical research to develop clinically relevant graft protective strategies. Areas covered: This review focuses on the most recent evidence based findings and ongoing clinical trials that might lead to emerging graft protective strategies in the field of clinical liver transplantation. New evidence-based findings in the donor preconditioning, organ preservation, and perioperative pharmacologic graft protection strategies in the recipient are reviewed. Expert commentary: Few strategies have been shown to exert some graft protective effects against ischemia reperfusion injury in recent clinical trials in liver transplantation. Among others, 'dynamic graft preservation' techniques have been emerging as more promising graft optimization strategies.
Insights
Liver transplant outcomes are improving with new strategies to protect organs from ischemia reperfusion injury. Dynamic graft preservation shows promise for optimizing liver grafts in clinical transplantation.
Area of Science:
- Hepatology
- Transplantation Surgery
- Organ Preservation
Background:
- Significant efforts are underway to understand and mitigate liver transplant pathophysiology, particularly ischemia reperfusion injury.
- Despite extensive research, translating experimental findings into clinical practice for liver transplantation has been challenging.
- Ongoing clinical research aims to develop effective graft protective strategies for liver transplantation.
Purpose of the Study:
- To review recent evidence-based findings and ongoing clinical trials on emerging graft protective strategies in liver transplantation.
- To highlight advancements in donor preconditioning, organ preservation, and perioperative recipient strategies.
- To identify promising approaches for improving liver graft outcomes.
Main Methods:
- Review of recent clinical trials and evidence-based findings.
- Focus on donor preconditioning techniques.
- Analysis of organ preservation methods and perioperative pharmacologic strategies in recipients.
Main Results:
- Few strategies have demonstrated significant graft protective effects against ischemia reperfusion injury in recent liver transplant trials.
- 'Dynamic graft preservation' techniques are emerging as particularly promising for graft optimization.
- Continued research is essential for developing clinically relevant protective concepts.
Conclusions:
- Emerging strategies, especially dynamic graft preservation, offer potential for improved liver graft outcomes.
- Further clinical validation is needed for novel protective concepts in liver transplantation.
- Advancements in organ preservation and perioperative care are crucial for expanding the donor pool and enhancing transplant success.
