Insights
Reduced-size liver grafts have significantly improved outcomes for pediatric liver transplantation, lowering mortality rates from 30-50% to 2-14%. This technique offers survival rates comparable to full-size grafts, making it a vital option for children with end-stage liver disease.
Area of Science:
- Pediatric Surgery
- Hepatology
- Transplantation Medicine
Context:
- End-stage liver disease in children historically had high mortality due to donor scarcity.
- Reduced-size liver grafts have been employed in pediatric liver transplantation since 1981.
- Pretransplant mortality rates have decreased significantly with the adoption of reduced-size grafts.
Purpose:
- To evaluate the efficacy and outcomes of reduced-size liver grafts in pediatric liver transplantation.
- To compare the results of reduced-size orthotopic liver transplantation with full-size grafts.
- To assess the impact of reduced-size grafts on pretransplant mortality in pediatric patients.
Summary:
- The use of reduced-size liver grafts in pediatric liver transplantation has dramatically decreased pretransplant mortality from 30-50% to 2-14%.
- Graft reduction techniques are guided by donor-recipient weight ratio and intra-operative measurements.
- Reduced-size grafts are now used in 30-50% of pediatric liver transplants, with one-year survival rates of 70-85%, comparable to full-size grafts.
- Innovations like bipartition and living-related donor transplantation represent advancements in graft reduction techniques.
Impact:
- Reduced-size liver transplantation has become a cornerstone in managing pediatric end-stage liver disease, significantly improving survival.
- The technique has made liver transplantation more accessible for pediatric patients by optimizing donor organ utilization.
- Ongoing advancements in graft reduction techniques promise further improvements in pediatric liver transplant outcomes.
Abstract:
The benefit of liver transplantation in children with end-stage liver disease is now well established. A few years ago, the scarcity of suitable pediatric donors was responsible for death in 30 to 50% of children on the waiting list and most of them died before the age of 3 years. Since 1981, the use of reduced-size graft in pediatric liver transplantation allowed a dramatic decrease of the pretransplant mortality rate which is now 2 to 14%. The choice of the reduction technique is based on two parameters; the first one is the donor recipient body weight ratio, the second one is the intra-operative measurement of the recipient's internal transverse basithoracic distance. Nowadays, 30 to 50% of the children undergoing a liver transplant, receive a reduced-size graft. The results of reduced-size orthotopic liver transplantation are comparable with full-size orthotopic liver transplantation; the one-year survival rate is 70 to 85%. These results justify the continued use of reduced-size liver transplantation in children with end-stage liver disease. Transplantation of two patients with one liver (bipartition) and liver transplantation from living related donor, which represents an improvement of the reduction technique, was recently performed successfully and may become a useful concept in pediatric liver transplantation.
