Expanding the Liver Donor Pool: Promise and Peril

Area of Science:

• Hepatology and Transplant Surgery
• Organ Donation and Procurement

Background:

• Liver transplantation is a critical treatment for end-stage liver disease, with a significant increase in procedures performed.
• Despite rising transplant numbers, the demand for liver grafts substantially outstrips donor availability.
• Addressing the organ shortage is paramount to improving patient outcomes and survival rates.

Purpose of the Study:

• To review advancements in expanding the liver donor pool over the last decade.
• To identify and discuss future challenges in utilizing a broader range of liver donors.
• To inform strategies for increasing organ availability for liver transplantation.

Main Methods:

• Literature review of recent progress in liver donor pool expansion.
• Analysis of strategies for utilizing extended criteria donors (ECDs) and marginal organs.
• Discussion of emerging techniques and ethical considerations in organ procurement.

Main Results:

• Significant progress has been made in accepting donors previously deemed unsuitable.
• The use of marginal organs has increased, contributing to a rise in transplant volumes.
• Technological and surgical innovations are enabling the use of more diverse donor organs.

Conclusions:

• Expanding the donor pool through innovative strategies is essential for meeting the growing demand for liver transplants.
• Overcoming future barriers, such as organ quality assessment and allocation policies, is critical for sustained progress.
• Continued research and development are needed to maximize the utilization of all potential liver donors.
