BACKGROUND & AIMS: In the past three decades, there have been major advances in the procedure and candidate selection for liver transplantation. The aim of this study was to assess the changes in outcomes of liver transplantations in the Unites States.
This observational study uses the Scientific Registry of Transplant Recipients (SRTR) that includes all liver transplants from 1987 to 2013 (N = 108 707 adults).
Four study cycles were introduced: 1987-1993, 1994-2000, 2001-2006, 2007-2013. The length of inpatient stay for receiving liver transplant substantially shortened (42-20 days), and so did the rate of acute post-transplant rejections (33-4%). The use of high risk donors and donors with chronic diseases increased significantly. Of transplant outcomes, despite recently reported unfavourable changes in clinico-demographic profile of liver transplant recipients (older age, substantial increases in all major comorbidities), the proportion of patients discharged alive increased from 78.2 to 91.8%. On the other hand, post-discharge 1-, 3- and 5-year mortality varied between 6.7 and 8.0%, 15.2 to 17.2% and 22.5 to 24.5%, respectively, and no consistent trend was found. Despite this, the rates of graft failure decreased: an approximately two-fold decrease in 1 year graft loss, and a 1.6-fold decrease in 5 year graft loss were observed.
Despite all improvements in liver transplant technique and patient management, the changes in post-transplant outcomes vary. While inpatient mortality, graft losses and post-transplant infect-ion rates improved substantially, post-discharge mortality remains stable because of increasing losses to competing risks in patients with non-liver comorbidities.
在过去三十年中,肝移植的手术操作和供体选择取得了重大进展。本研究旨在评估美国肝移植结局的变化。
这项观察性研究使用了移植受者科学注册系统(SRTR),该系统涵盖了1987年至2013年的所有肝移植病例(N = 108707例成人)。
引入了四个研究周期:1987 - 1993年、1994 - 2000年、2001 - 2006年、2007 - 2013年。接受肝移植后的住院时间大幅缩短(从42天降至20天),移植后急性排斥反应率也显著降低(从33%降至4%)。高风险供体和患有慢性疾病的供体的使用显著增加。在移植结局方面,尽管最近有报道称肝移植受者的临床人口统计学特征出现了不利变化(年龄增大,所有主要合并症大幅增加),但出院时存活患者的比例从78.2%增至91.8%。另一方面,出院后1年、3年和5年的死亡率分别在6.7%至8.0%、15.2%至17.2%和22.5%至24.5%之间,未发现一致趋势。尽管如此,移植失败率有所下降:观察到1年移植肝丢失率下降了约两倍,5年移植肝丢失率下降了1.6倍。
尽管肝移植技术和患者管理有了诸多改进,但移植后结局的变化各不相同。虽然住院死亡率、移植肝丢失率和移植后感染率大幅改善,但出院后死亡率保持稳定,这是因为非肝脏合并症患者面临的竞争风险导致的死亡人数增加。
