Clinical Report: Long-Term Outcomes for Living Liver Donors

Overview

Living donor liver transplantation (LDLT) addresses organ shortages but raises concerns about donor safety. This review of 17 studies highlights that while early complications like biliary issues and incisional hernias are common, long-term donor mortality remains low and quality of life is generally preserved.

Background

Liver transplantation is the definitive treatment for end-stage liver disease, yet donor shortages limit access. LDLT has emerged as a solution, with the first successful adult transplant in 1993. Donor safety is paramount, with surgical techniques evolving to balance graft volume and donor risk. Although short-term donor outcomes are well studied, long-term effects remain less clear due to limited data and follow-up challenges.

Data Highlights

Key Findings

• Donor in-hospital mortality is low at approximately 0.2%, but complications occur in 15-40% within the first year post-donation.
• Biliary complications, including leakage and strictures, are the most frequent donor issues, with early bile leaks occurring in 5-15% of donors.
• Bile duct strictures can develop long-term, especially following early bile leakage, though persistent strictures are rare (up to 1.7%).
• Incisional hernias and incision site discomfort are common long-term complications reported among donors.
• Donor safety has improved with surgical advances, including increased use of left liver grafts and minimally invasive techniques.
• Long-term quality of life for donors is generally maintained, but comprehensive data remain limited due to variable follow-up and study designs.

Clinical Implications

Clinicians should counsel potential living liver donors about the risks of biliary complications and incisional hernias, emphasizing the low mortality but notable morbidity rates. Advances in surgical techniques may reduce donor risk, and long-term follow-up is essential to monitor and manage persistent complications. Providing accurate, evidence-based information supports informed consent and donor safety.

Conclusion

Living donor liver transplantation offers a vital solution to organ shortages with low donor mortality, but biliary and incisional complications remain significant concerns. Continued research and long-term monitoring are crucial to optimize donor outcomes and uphold ethical standards.
