Study & Design

Study Type
INTERVENTIONAL
Study Design
SINGLE_GROUP
Primary Outcome Measures
NameTimeMethod
Patient and Graft Survival30 days

Patient survival after liver transplantation and liver graft survival will be assessed at 30-days post-op as a composite outcome measure. This will be recorded as yes/no outcome.

Secondary Outcome Measures
NameTimeMethod
Primary non-function10 days

This is irreversible graft dysfunction requiring emergency liver replacement during the first 10 days after liver transplantation, in the absence of technical or immunological causes.

This will be compared with matched controls of livers undergoing continuous NMP and SCS

Adverse events, transplantation and organ discard rates.30 days

This composite outcome aims to establish safety and feasibility as well as organ utilisation. It will be compared with matched controls of livers undergoing continuous NMP and SCS

Biliary investigation or intervention6 months

In order to capture the incidence of ischaemic cholangiopathy, any biliary investigation (such as magnetic resonance imaging) or intervention (such as endoscopic retrograde cholangiopancreatography) will be recorded and compared with matched controls of livers undergoing continuous NMP and SCS

Patient and Graft Survival12 months

Patient survival after liver transplantation and liver graft survival will be assessed at 12 months post-op as a composite outcome measure. This will be recorded as yes/no outcome and compared controls undergoing continuous NMP and SCS

Peak serum AST (U/L)7 days

The highest AST level recorded in the first 7 days post-transplant will be identified. This is a surrogate marker for longer-term outcome. It will be compared with matched controls of livers undergoing continuous NMP and SCS

Early allograft dysfunction (EAD)7 days

This is a composite score which is used to predict longer-term outcome. It comprises: bilirubin \>or=10mg/dL on day 7 post-transplant, international normalized ratio \>or=1.6 on day 7 post-transplant, and alanine or aspartate aminotransferases \>2000 IU/L within the first 7 days post-transplant. This will be compared with matched controls of livers undergoing continuous NMP and SCS
