A randomized-controlled trial of ischemia-free liver transplantation for end-stage liver disease
Abstract
BACKGROUND & AIMS
Ischemia-reperfusion injury (IRI) has thus far been considered as an inevitable component of organ transplantation, compromising outcomes, and limiting organ availability. Ischemia-free organ transplantation is a novel approach designed to avoid IRI, with the potential to improve outcomes.
METHODS
In this randomized, controlled clinical trial, recipients of livers from donors after brain death were randomly assigned to receive either an ischemia-free or a 'conventional' transplant. Primary end point was the incidence of early allograft dysfunction. Secondary end points included complications related to graft IRI.
RESULTS
65 out of 68 randomized patients underwent transplants and were included in the analysis. 32 patients received ischemia-free liver transplantation (IFLT), and 33 received conventional liver transplantation (CLT). Early allograft dysfunction occurred in 2 (6%) randomized to IFLT and in 8 (24%) randomized to CLT (difference, -18%; 95% CI, -35% to -1%; P=.044). Post-reperfusion syndrome occurred in 3 (9%) randomized to IFLT and in 21 (64%) randomized to CLT (difference, -54%; 95% CI, -74% to -35%; P < .001). Non-anastomotic biliary strictures diagnosed with protocol magnetic resonance cholangiopancreatography at 12 months were observed in 2 recipients (8%) randomized to IFLT and in 9 recipients (36%) randomized to CLT (difference, -28%; 95% CI, -50% to -7%; P = .014). The comprehensive complication index at one year after transplantation was…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 68 participants or records.
