Current status of liver transplantation

Area of Science:

• Hepatology and Transplant Surgery
• Organ Donation and Allocation

Background:

• Liver transplantation is the primary treatment for end-stage liver disease, facing increasing demand that outstrips donor organ availability.
• The criteria for organ allocation prioritize patients likely to benefit most, but a broader application would exacerbate donor shortages.
• Emerging challenges include disease recurrence post-transplant and shifts in patient demographics, with a rise in hepatitis C and alcoholic cirrhosis cases.

Purpose of the Study:

• To review current challenges and innovations in liver transplantation, focusing on organ donor limitations and strategies to expand access.
• To evaluate the efficacy and safety of utilizing marginal donors, such as non-heart-beating donors (NHBDs), and organ splitting techniques.
• To discuss the growing role of living donor liver transplantation and its implications for donor safety and transplant activity.

Main Methods:

• Review of current literature and clinical practices in liver transplantation.
• Analysis of outcomes associated with different donor sources, including marginal and living donors.
• Examination of techniques such as organ splitting for maximizing graft utilization.

Main Results:

• Non-heart-beating donors (NHBDs) are proving to be a viable source of organs when carefully selected.
• Liver splitting has enabled successful transplantation in pediatric and adult recipients from a single organ, though dual adult transplantation remains challenging.
• Living donor liver transplantation has significantly increased, contributing substantially to overall transplant numbers despite donor safety concerns.

Conclusions:

• Addressing the organ shortage in liver transplantation requires innovative approaches, including the use of marginal donors and organ splitting.
• Living donor transplantation plays an increasingly critical role, necessitating continued focus on donor safety protocols.
• Optimizing organ utilization and exploring all potential donor sources are crucial for meeting the growing demand for liver transplants.
