    Abstract:
    IMPORTANCE: While orthotopic liver transplantation (OLT) is a durable life-saving treatment for patients with irreversible liver disease, the waiting list mortality rate for children younger than 6 years is 4 times higher than for children aged 11 to 17 years and adults owing to scarce availability of size-appropriate grafts for transplantation. OBJECTIVE: To compare long-term outcomes for children (aged ≤18 years) undergoing OLT using grafts from donation after circulatory death (DCD) and donation after brain death (DBD). DESIGN, SETTING, AND PARTICIPANTS: Retrospective study using case-control matched groups at a university transplant center. All patients aged 18 years and younger who underwent OLT using DCD organs between February 1, 1990, and November 30, 2010, at the University of California, Los Angeles, were matched in a 1 to 3 ratio with patients who received primary OLT from DBD donors within a 12-month period. Other matching criteria included recipient age, weight, cause of liver disease, and acuity of illness. Outcomes after OLT were compared for DCD (n = 7) and DBD (n = 21) donors. The median follow-up was 4.5 years. MAIN OUTCOMES AND MEASURES: The primary outcome measure was graft failure-free survival; the secondary end point was the development of ischemic cholangiopathy. RESULTS: Comparing DCD and DBD groups, recipient median age (28.4 vs 20.1 months, respectively; P = .80), weight (12.0 vs 11.6 kg, respectively; P = .87), Model for End-Stage Liver Disease/Pediatric End-Stage Liver Disease score (19 vs 11, respectively; P = .48), and donor age (24.0 vs 13.1 months, respectively; P = .72) were similar. For the DCD donors, the median donor warm ischemia duration was 24 minutes. Liver test results were similar for both groups at 1 week and 3, 6, and 12 months following OLT. Ten-year patient and graft survival rates for both DCD and DBD were 100%. Neither ischemic cholangiopathy nor vascular complications occurred in the DCD group. Biliary anastomotic strictures occurred in 1 DCD patient and 3 DBD patients. CONCLUSIONS AND RELEVANCE: Our study showed excellent long-term outcomes with liver transplantation in children using DCD organs. Use of liver grafts procured after circulatory death is an effective approach to expand the donor pool and remains an untapped resource for children with end-stage liver disease.
