Insights
A novel surgical technique using a temporary patch graft allows for the safe transplantation of reduced adult livers into small pediatric recipients, improving abdominal closure and potentially reducing wait times for liver transplants.
Area of Science:
- Pediatric surgery
- Organ transplantation
- Surgical innovation
Background:
- Donor liver shortage significantly impacts pediatric liver transplantation.
- Reduced adult donor livers are often too large for small children (<8kg).
- Tight abdominal closure in pediatric liver recipients can cause complications.
Observation:
- A technique using a temporary expanded polytetrafluoroethylene (ePTFE) patch graft was employed.
- This facilitated comfortable abdominal wound closure in two pediatric patients.
- Delayed primary abdominal closure was successful 4-5 days post-transplant.
Findings:
- The ePTFE patch graft technique enabled the use of reduced adult livers in small pediatric recipients.
- Liver grafts showed marked size reduction by the time of delayed closure.
- The method allowed for secure abdominal closure that would have been otherwise impossible.
Implications:
- This technique increases the flexibility of donor liver utilization for pediatric recipients.
- It has the potential to decrease waiting times for liver transplantation in small children.
- The approach may reduce mortality rates for pediatric patients on the liver transplant waiting list.
Abstract:
A shortage of donor organs of appropriate size causes lengthy delays for many children awaiting liver transplantation, and results in the death of some children on the active waiting list. A major contribution to overcoming this problem has been the use of reduced livers from adult donors. However, reduced adult livers are frequently too large to be used for small pediatric recipients ( less than 8 kg) because of the serious problems which occur when too tight an abdominal closure is attempted. We report a technique which we have used successfully in 2 children, involving the insertion of a temporary patch graft of expanded polytetrafluoroethylene. This allowed comfortable abdominal wound closure, which would not otherwise have been possible. Delayed primary closure of the abdomen 4-5 days later was achieved without difficulty in each case, the liver grafts having decreased markedly in size by this time. The technique allows greater flexibility in the use of donor livers for pediatric recipients, and thus has the potential to reduce waiting times and deaths on the waiting list for small children requiring liver transplantation.
