In China, the cases of liver transplantation (LT) from donation after citizens' death have rose year by year since the citizen-based voluntary organ donor system was initiated in 2010. The objective of our research was to investigate the early postoperative and late long-term outcomes of LT from donation after brain death (DBD) and donation after circulatory death (DCD) according to the current organ donation system in China.
Sixty-two consecutive cases of LT from donation after citizens' death performed in our hospital between February 2012 and June 2017 were examined retrospectively for short- and long-term outcomes. These included 35 DCD LT and 27 DBD LT.
Subsequent median follow-up time of 19 months and 1- and 3-year graft survival rates were comparative between the DBD group and the DCD group (81.5% and 66.7% versus 67.1% and 59.7%; = 0.550), as were patient survival rates (85.2% and 68.7% versus 72.2% and 63.9%; = 0.358). The duration of ICU stay of recipients was significantly shorter in the DBD group, in comparison with that of the DCD group (1 versus 3 days, = 0.001). Severe complication incidence (≥grade III) after transplantation was identical among the DBD and DCD groups (48.1% versus 60%, = 0.352). There was no significant difference in postoperative mortality between the DBD and DCD groups (3 of 27 cases versus 5 of 35 cases). Twenty-one grafts (33.8%) were lost and 18 recipients (29.0%) were dead till the time of follow-up. Malignancy recurrence was the most prevalent reason for patient death (38.8%). There was no significant difference in incidence of biliary stenosis between the DBD and DCD groups (5 of 27 cases versus 6 of 35 cases, = 0.846).
Although the sample size was small to some extent, this single-center study first reported that LT from DCD donors showed similar short- and long-term outcomes with DBD donors and justified the widespread implementation of voluntary citizen-based deceased organ donation in China. However, the results should be verified with a multicenter larger study.
自2010年中国启动公民自愿器官捐献体系以来,公民逝世后器官捐献肝移植(LT)病例数逐年上升。本研究的目的是根据中国现行器官捐献体系,调查脑死亡后捐献(DBD)和心脏死亡后捐献(DCD)肝移植的术后早期和晚期长期结局。
回顾性分析2012年2月至2017年6月在我院连续进行的62例公民逝世后器官捐献肝移植病例的短期和长期结局。其中包括35例DCD肝移植和27例DBD肝移植。
DBD组和DCD组的后续中位随访时间为19个月,1年和3年移植物存活率具有可比性(81.5%和66.7%对比67.1%和59.7%;P = 0.550),患者存活率也是如此(85.2%和68.7%对比72.2%和63.9%;P = 0.358)。与DCD组相比,DBD组受者的ICU住院时间显著更短(1天对比3天,P = 0.001)。DBD组和DCD组移植后严重并发症发生率(≥Ⅲ级)相同(48.1%对比60%,P = 0.352)。DBD组和DCD组术后死亡率无显著差异(27例中有3例对比35例中有5例)。截至随访时,21个移植物(33.8%)丢失,18例受者(29.0%)死亡。恶性肿瘤复发是患者死亡的最常见原因(38.8%)。DBD组和DCD组胆管狭窄发生率无显著差异(27例中有5例对比35例中有6例,P = 0.846)。
尽管样本量在一定程度上较小,但这项单中心研究首次报告DCD供体肝移植与DBD供体肝移植的短期和长期结局相似,并证明了中国公民自愿逝世后器官捐献广泛实施的合理性。然而,结果应通过多中心更大规模研究进行验证。
