INTRODUCTION: Dual hypothermic oxygenated machine perfusion (DHOPE) of the liver has been advocated as a method to reduce ischemia-reperfusion injury. This study aimed to determine whether DHOPE reduces IR injury of the bile ducts in DCD liver transplantation.

MATERIALS AND METHODS: In a recently performed phase 1-trial, ten DCD livers were preserved with DHOPE after static cold storage (SCS) (www.trialregister.nl NTR4493). Bile duct biopsies were obtained at the end of SCS (before DHOPE; baseline) and after graft reperfusion in the recipient. Histological severity of biliary injury was graded according to an established semi-quantitative grading system. Twenty liver transplantations using DCD livers not preserved with DHOPE served as control.

RESULTS: Baseline characteristics and the degree of bile duct injury at baseline (end of SCS) were similar between both groups. In controls, degree of stroma necrosis (P=0.002) and injury of the deep peribiliary glands (P=0.02) increased after reperfusion, compared to baseline. In contrast, in DHOPE preserved livers the degree of bile duct injury did not increase after reperfusion. Moreover, there was less injury of deep peribiliary glands (P=0.04) after reperfusion in the DHOPE group, compared to controls.

CONCLUSION: This study suggests that DHOPE reduces ischemia-reperfusion injury of bile ducts after DCD liver transplantation. This article is protected by copyright. All rights reserved.
