About

This study aimed to evaluate fatty liver grafts, considered as unsuitable for upfront liver transplantation, by using normothermic perfusion. Grafts have to be allocated to one of 3 liver transplantation centres of Paris. After evidence of viability while on perfusion, these grafts will be transplanted to recipients with an estimated waiting time > 6 months.

Full description

In this study, the coordinator investigator proposes to build a platform for perfusing in normothermic conditions all grafts with histologically proven macrosteatosis ≥ 30% that will be considered as unsuitable for upfront LT. These grafts have to be alloacted to one of the 3 liver transplantation centers of Assistance Publique des Hôpitaux de Paris. Eligible grafts (macrosteatosis ≥ 30%, no severe fibrosis or cirrhosis) will be shipped to the platform for normothermic perfusion. Perfusion will be started provided that cold ischemia time do not exceed 8 hours. Parameters of grafts viability (lactates, bile production, flow) will be monitored. After a minimum of 4 hours of normothermic perfusion (not exceeding 16 hours), grafts fulfilling strict criteria (homogeneous aspect of the liver without any necrotic regions, lactates < 2.5 mmol/l and continuous production of bile with at least one of the following criteria: pH of perfusate > 7.3, arterial flow > 150 ml/min and portal flow > 500 ml/min, homogeneous perfusion of the graft) will be considered suitable for transplantation. Recipient will be transferred to the operating room, and first phase of LT (i.e, laparotomy and total hepatectomy) will be started. Simultaneously, grafts will be shipped to the center of initial allocation. Perfusion will be pursued during the transport from the platform to the recipient. Recipients (≥18 years and ≤ 70 years) have to be enlisted for LT with an estimated waiting time > 6 months (i.e., MELD score < 25) and who signed an informed consent.
