A 64-year-old male with a history of cirrhosis due to viral hepatitis C was successfully treated with DAAs. During surveillance a hypervascular tumour (largest diameter 3.5 cm) with wash-out in the portal phase was detected in the left lobe. At the liver tumour board meeting the multidisciplinary team evaluated the patient based on a multi-parametric composite assessment of liver function, portal hypertension, extent of hepatectomy, expected volume of the future liver remnant, performance status and patients’ co-morbidities.

The tumour board suggested a liver resection of the involved segment. When informing the patient, he asks about the risk of morbidity and mortality.

What is the expected perioperative mortality of liver resection in cirrhotic patients?
