Normothermic regional perfusion (NRP) has gained widespread adoption in multiple European countries. The aim of this study was to examine the influence of thoracoabdominal-NRP (TA-NRP) on the utilization and outcomes of liver, kidney, and pancreas transplantation in the United States.
Using the US national registry data between 2020 and 2021, donation after circulatory death (DCD) donors were separated into 2 groups: DCD with TA-NRP and without TA-NRP. There were 5234 DCD donors; among them 34 donors were with TA-NRP. After 1:4 propensity score matching, the utilization rates were compared between DCD with and without TA-NRP.
Although the utilization rates of kidney and pancreas were comparable ( = 0.71 and = 0.06, 94.1% versus 95.6% and 8.8% versus 2.2%, respectively), that of liver in DCD with TA-NRP was significantly higher ( < 0.001; 70.6% versus 39.0%). Among 24 liver transplantations, 62 kidney transplantations, and 3 pancreas transplantations from DCD with TA-NRP, there were 2 liver grafts and 1 kidney graft that failed within 1 y after transplantation.
TA-NRP in the United States significantly increased the utilization rate of abdominal organs from DCD donors with comparable outcomes after transplantation. Increasing use of NRP may expand the donor pool without compromising transplant outcomes.
常温区域灌注(NRP)已在多个欧洲国家广泛应用。本研究的目的是探讨胸腹常温区域灌注(TA-NRP)对美国肝脏、肾脏和胰腺移植的利用情况及结局的影响。
利用2020年至2021年美国国家登记数据,将循环死亡后捐赠(DCD)供体分为两组:接受TA-NRP的DCD供体和未接受TA-NRP的DCD供体。共有5234名DCD供体;其中34名供体接受了TA-NRP。经过1:4倾向评分匹配后,比较接受和未接受TA-NRP的DCD供体的利用率。
虽然肾脏和胰腺的利用率相当(P=0.71和P=0.06,分别为94.1%对95.6%和8.8%对2.2%),但接受TA-NRP的DCD供体肝脏的利用率显著更高(P<0.001;70.6%对39.0%)。在接受TA-NRP的DCD供体进行的24例肝脏移植、62例肾脏移植和3例胰腺移植中,有2例肝脏移植物和1例肾脏移植物在移植后1年内失败。
美国的TA-NRP显著提高了DCD供体腹部器官的利用率,移植后结局相当。增加NRP的使用可能会扩大供体库,而不影响移植结局。
