Acute and Chronic

Liver Disease



Contents

• Investigations

• Acute Liver disease

• Chronic Liver Disease



Normal Liver Function

• Protein synthesis and degradation: – albumin, transort roteins, clotting !actors,

• Carbohydrate metabolism

• Liid metabolism• "ile acid metabolism

• "ilirubin metabolism

• #ormone inactivation• Drug inactivation and e$cretion

• Immunological !unction



Liver !unction tests %

• "ilirubin – Con&ugated and 'ncon&ugated

• AL()A*( levels

• Al+aline Phoshatase• g(

• Albumin

• IN-

• F"C



Liver !unction tests .

• #eatitis antibodies: A, ", C/0D, 1• 1"2, (o$o, C32, Letosirosis

Imaging

• 'ltrasound – Liver substance, lesions, gallbladderand biliary tree, vessels 4Doler e$am5, sleensi8e and varices

• C( scan – con!irm small lesions, see ancreas• 3-I o! Liver – classi!y smaller lesions

• 3-CP: M agnetic r esonancec holangio pancreatography, to see the biliary tree

• 1-CP: E ndoscopic r etrogradec holangio pancreatography – diagnostic andtheraeutic: stones, strictures etc0



3-CP



1-CP



Liver "iosy

• 2ery use!ul !or con!irming a diagnosis,staging degree o! in!lammation and)or!ibrosis, iron content, mass lesions

• Contraindications: "leeding disorders,ascites, small liver, uncooerative atient

• Comlications: "leeding, ain, er!oration

9aundice

• Pre heatic

– #aemolysis

– Con&ugation abnormalities

• #eatic – any liver disease, acute or

chronic

• Post heatic – bstruction
