Background
Cholestatic jaundice is a condition in which there is a blockage in the flow of bile movement from the liver to the duodenum.
The two basic distinctions are : intrahepatic biliary stasis (hepatocellular jaundice) and mechanical biliary obstruction,
bearing in mind that several intrahepatic causes of cholestatic jaundice can mimic extrahepatic obstruction to varying degree.
Ultrasound is the first imaging modality used in the algorithm for the investigation of cholestatic jaundice.
Further imaging depends on whether the bile ducts are dilated.
If the bile ducts are dilated and an ultrasound fails to demonstrate a cause,
further imaging depends on a provisional clinical diagnosis.
Investigations may the include CT scan of the abdomen,
Magnetic Resonance Cholangiopancreatography (MRCP) and Endoscopic US (EUS).
If the bile ducts are not dilated,
hepatocellular causes of jaundice should be excluded prior to further imaging
