Transplant centers have traditionally relied upon procurement teams from their own programs (transplant program procurement team [TPT]) to recover donation after circulatory death (DCD) livers and rarely use surgical procurement teams not affiliated with the recipient center (nontransplant program procurement team [NTPT]). However, in the era of wider geographic organ sharing, greater reliance on NTPTs is often necessary.
We used national data to study the association between the origin of the donor procurement team (NTPT versus TPT) and the risk of DCD liver allograft failure.
Five hundred NTPT and 2257 TPT DCD transplants were identified: 1-y graft survival was 88.9 and 88.6%, respectively ( = 0.962). In a multivariable model, the origin of the procurement team was not associated with graft failure NTPT versus TPT (hazard ratio, 0.92; 95% confidence interval, 0.71-1.22; = 0.57) but rather with known risks for DCD graft loss including donor age, degree of recipient illness, cold ischemic time, and retransplantation. The overall incidence of retransplantation and ischemic cholangiopathy as an indication for retransplantation were similar between NTPT and TPT.
This data suggests that transplant centers may be able to safely use DCD livers recovered by local surgical teams.
传统上,移植中心依靠自身项目的获取团队(移植项目获取团队[TPT])来获取心脏死亡后捐赠(DCD)肝脏,很少使用与受者中心无关的外科获取团队(非移植项目获取团队[NTPT])。然而,在更广泛的地理器官共享时代,往往需要更多地依赖非移植项目获取团队。
我们使用全国数据研究供体获取团队的来源(非移植项目获取团队与移植项目获取团队)与DCD肝移植失败风险之间的关联。
共识别出500例非移植项目获取团队和2257例移植项目获取团队的DCD移植:1年移植物存活率分别为88.9%和88.6%(P = 0.962)。在多变量模型中,获取团队的来源与移植物失败无关(非移植项目获取团队与移植项目获取团队相比,风险比为0.92;95%置信区间为0.71 - 1.22;P = 0.57),而是与DCD移植物丢失的已知风险相关,包括供体年龄、受者疾病程度、冷缺血时间和再次移植。非移植项目获取团队和移植项目获取团队之间再次移植的总体发生率以及作为再次移植指征的缺血性胆管病发生率相似。
这些数据表明,移植中心或许能够安全地使用由当地外科团队获取的DCD肝脏。
