Abstract

Domino liver transplantation (DLT) utilizes the explanted liver of one liver transplant recipient as a donor graft in another patient. While there may be unique risks associated with DLT, it is unclear if DLT has less favorable long-term outcomes than deceased donor liver transplantation (DDLT). We used a propensity score matching approach to compare the outcomes of DLT recipients to DDLT recipients. The United Network for Organ Sharing (UNOS) registry was queried for patients undergoing DLT or DDLT in 2002–2016. Each DLT recipient was matched to a unique DDLT recipient to compare mortality and graft failure. There were 126 DLT and 62 835 DDLT recipients meeting inclusion criteria. After propensity score matching on recipient pre-transplant characteristics, 123 DLT cases were matched to DDLT controls from the same UNOS region. On stratified Cox proportional hazards regression, DLT incurred no increase in the hazard of mortality [hazard ratio (HR) = 1.4; 95% confidence interval (CI): 0.8, 2.7; P = 0.265] or graft failure (HR = 1.2; 95% CI: 0.7, 2.1; P = 0.556) compared to DDLT. Using a large national registry, a propensity-matched analysis found no increased risk of mortality or graft failure associated with DLT compared to DDLT.
