[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”Diagnosis and clinical signs”][vc_column_text]This patient has a so-called Mercedes-Benz scar in his upper abdominal area indicative of a liver transplant.[/vc_column_text][/vc_accordion_tab][vc_accordion_tab title=”Discussion”][vc_column_text]Liver transplantation has become a well tolerated procedure with good outcomes for patients with end stage liver disease. The first liver transplant was in 1963, and in elective transplants, 1-year survival rates now go beyond 80-90%.

Indications for liver transplantation include:

  • acute liver failure e.g. paracetamol toxicity or fulminant Wilson’s disease
  • primary biliary cirrhosis
  • primary sclerosing cholangitis
  • autoimmune hepatitis
  • alcohol liver disease (with guidelines on abstinence except maybe on younger, acute liver failure patients
  • hepatitis B and C
  • neuroendocrine tumours (only malignancy where transplantation occurs for palliation)
  • small hepatocellular carcinomas

This patient demonstrates the classic scar of a liver transplant, termed the Mercedes-Benz scar due to its resemblance to the car’s symbol. However, newer patients due to advances in surgical techniques now have a reduced scar, which can be found here.

Poorer outcomes are associated with:

  • extremes of age (young and elderly)
  • black and oriental ethnicity
  • initial liver disease

In acute liver failure, the King’s College Hospital criteria is used as a marker:

Paracetamol toxicity:

  • pH < 7.30
  • prothrombin time >100 seconds
  • serum creatinine >300 μmol/l – if grade III/IV encephalopathy

Non-paracetamol acute liver failure:

  • cause – indeterminate hepatitis, halothane hepatitis or an idiosyncratic drug reaction
  • <10- or >40- years of age
  • jaundice to encephalopathy time > 7-days
  • prothrombin time >50 seconds
  • serum bilirubin >300 μmol/l

The best outcomes for transplantation have been found in primary biliary cirrhosis.

The reasons there are poor transplant rates among patients with alcohol induced liver disease relates to the possible reversibility were the patient to cease drinking alcohol; associated alcohol dependence and risks of relapse after abstinence and finally associated co-morbidities (e.g. alcohol induced cardiomyopathy).
