What are some pathological changes which occur in cirrhosis?
Infiltrating lymphocyte
Extracellular matrix proteins
Apoptotic hepatocyte
Activated kupffer cells
Sinusoid lumen with increased resistance to blood flow
What are the clinical presentation of compensates chronic liver disease?
Routinely detected on screening tests
Abnormality of liver function tests

Hepatocellular carcinoma
What is ascites?
Accumulation of fluid in the abdomen
What are the clinical features of ascites?
Dullness in flanks and shifting dullness
US can confirm
Spiders, palmar erythema, abnormal veins, umbilical nodule, JVP elevation
Explain the diagnosis of ascites
Diagnostic paracentesis
Protein and albumin conc.
Cell count
SAAG
Explain SAAG (serum ascites albumin gradient) score
More than 1.1 then suggest portal hypertension
Less hen non portal causes
What are some routine ascitic fluid analysis?
Cell count
Protein
Albumin
What can cause a SAAG of more than 1.1g/dl?
Portal hypertension
CHF
Constructive pericarditis
What can cause a SAAG of less than 1.1g/dl?
Malignancy
Tuberculosis
Pancreatic
What are the treatment options for ascites?
Diuretics
Large volume paracentesis
TIPS - reduces portal pressure
Aquaretic
Liver transplant
What is hepatorenal syndrome?
Decreased renal blood flow
Decreased GFR
Sodium retention
Due to a decrease in effective blood volume
What is the treatment for hepatorenal syndrome?
Volume expansion with albumin
Vasopressors
TIPSS
Liver transplant
What are varices due to?
Portal hypertension
What are varices at portosystemic anastomoses?
Caput medusa
Oesophageal and gastric
Rectal
Posterior abdominal wall
Stomal
What is the management for varices?
Resuscitate patient as medical emergency
Good IV access
Blood transfusion
Endoscopy
What is the treatment for varices?
Endoscopic band ligation
Add terlipressin for control
TIPSS for rebleeding after banding
