[Reduced-size liver transplants in children]
Insights
Reduced-size liver transplantation offers a solution for pediatric end-stage liver disease by using partial liver grafts. This technique expands the donor pool, showing comparable survival rates to full-sized liver transplants.
Area of Science:
- Hepatology
- Pediatric Surgery
- Transplantation Medicine
Background:
- Pediatric end-stage liver disease necessitates liver transplantation.
- Scarcity of size-matched liver allografts limits treatment options for children.
- Reduced-size liver transplantation utilizes partial liver grafts to address size disparity.
Observation:
- The first pediatric reduced-size liver transplantation in Israel involved a 4-year-old boy with fulminant hepatic failure.
- A left hepatic lobe allograft from an adult donor was successfully transplanted.
- The patient recovered well and was discharged 9 months post-transplant.
Findings:
- Reduced-size liver transplantation overcomes donor-recipient size mismatch in pediatric liver recipients.
- This technique significantly increases the potential donor pool for children requiring liver transplants.
- Survival rates and retransplantation rates for reduced-size liver allografts are comparable to full-sized grafts.
Implications:
- Reduced-size liver transplantation is a viable and effective option for pediatric liver failure.
- The procedure expands treatment possibilities, potentially saving more young lives.
- Further adoption of this technique can alleviate donor organ shortages in pediatric transplantation.
Abstract:
Orthotopic liver transplantation is now used for children with end-stage liver disease, but the scarcity of size-matched liver allografts for children has limited its use. Reduced-size liver transplantation, in which only part of the liver is used as a graft, overcomes size disparity and increases significantly the potential donor pool for children. A 4-year-old boy with fulminating hepatic failure due to hepatitis became the first case of reduced-size liver transplantation in Israel. A left hepatic lobe allograft from an adult donor was used. The boy is home and well 9 months after transplantation. Reduced-size liver transplantation was first performed in a child by Bismuth and Houssin in 1984. Reports from several centers show that survival of recipients of reduced-size liver allografts and the rate of retransplantation does not differ significantly from that in recipients of full-sized livers.
