Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Main Objective:
To compare the effect of NMP versus SCS in preventing preservation injury and graft dysfunction, as measured by highest transaminase levels during the first week after liver transplantation.
Secondary Objectives:
* To compare graft and patient survival between the NMP and SCS steatotic livers.
* To compare the liver biochemical function between the NMP and SCS steatotic livers.
* To compare the physiological response to the reperfusion between the NMP and SCS steatotic livers.
* To compare the evidence of reperfusion injury between the NMP and SCS steatotic livers.
* To compare the evidence of ischemic cholangiopathy between the NMP and SCS steatotic livers.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Static cold storage (SCS)
Traditional method of organ preservation which involves flushing of cold preservation solution following complete dissection and interruption of blood supply to the donor organ. Although cold preservation slows metabolism by 10- to 12-fold, substantial anaerobic activity continues even at ice temperature. This lead to the generation of reactive oxygen species that are the basis of ischaemia-reperfusion injury, when the organ is re-exposed to oxygenated blood at the time of transplantation. This damage, exacerbated by any prior injury, limits the maximum safe preservation time of the donor organ.
Static cold storage (SCS)
The liver is flushed and cooled with specialist preservation fluid, then stored in an icebox.
Normothermic machine perfusion (NMP)
The main goal of NMP is to optimize graft preservation by mimicking physiological conditions. The perfused organ is supplied with nutrients and oxygen to maintain metabolic hemostasis. Under these conditions, ATP and glycogen reserves can be maintained or actively restored. At the same time, toxic products from the cellular milieu are continuously eliminated, so the cell-mediated injury phase of reperfusion injury can be minimized. Thus, ischemic injury is avoided and the activation of cell death cascades is prevented. This allows both hepatocellular and biliary protection.
Normothermic machine perfusion (NMP)
During NMP, the liver is perfused with oxygenated blood, medications and nutrients at normal body temperature to maintain a physiological milieu.
