1
Q

Definition of cirrhosis?

A

o Cirrhosis develops progressively as a result of damage to the liver
o Normal smooth liver surface becomes distorted, nodular and fibrosed
 Distortion of hepatic vasculature, increased intrahepatic resistence and portal hypertension
 Damaged hepatocytes cause less synthesis of clotting factors and metabolic detoxification

Q

Types of cirrhosis?

A

o Compensated – liver still functions effectively and no/few symptoms

o Decompensated – liver damaged where it cannot function adequately and clinical complications present (jaundice, ascites, variceal haemorrhage, hepatic encephalopathy)

Q

Diagnosing cirrhosis in primary care - when to perform transient elastography?

A

Transient elastography if:
 Patient with Hep C infection
 Men drinking >50 units per week for months
 Women drinking >35 units per week for months
