Living donor liver transplantation for children with liver failure and concurrent multiple organ system failure

Area of Science:

• Pediatric Hepatology
• Transplantation Surgery
• Critical Care Medicine

Background:

• Pediatric liver failure with multiple organ system failure (MOSF) is associated with poor outcomes.
• Waiting for cadaveric allografts can lead to disease progression and decreased survival.
• Living donor liver transplantation (LDLT) presents a potential alternative for this high-risk group.

Purpose of the Study:

• To evaluate the efficacy and outcomes of LDLT in pediatric patients with MOSF.
• To compare LDLT with cadaveric donation (CAD) in this specific patient population.
• To assess the impact of reduced wait times and ischemia on survival.

Main Methods:

• Retrospective chart review of pediatric liver transplant recipients with MOSF.
• Comparison of patient profiles, pre-transplantation status, and postoperative complications between LDLT and CAD groups.
• Analysis of wait times, cold ischemia times, and patient survival rates at 30 days and 6 months.

Main Results:

• LDLT recipients (n=8) had shorter mean wait times (3.5 days) and cold ischemia times (3.8 hours) compared to CAD recipients (n=11; 6.5 days and 7.9 hours, respectively).
• Pre-transplantation characteristics and postoperative complications were similar between the groups.
• Thirty-day survival was 88% for LDLT vs. 45% for CAD; 6-month survival was 63% for LDLT vs. 27% for CAD.

Conclusions:

• LDLT is associated with significantly improved survival rates in pediatric patients with MOSF compared to CAD.
• Shorter wait and ischemia times in LDLT may contribute to better patient outcomes.
• Timely transplantation via LDLT before critical organ failure progression is crucial for survival.
