Know the place of imaging techniques in the exploration of cholestatic jaundice. Discuss the main causes of jaundice in adults according to the seat of the obstruction on the biliary tract. Describe iconographic aspects of the main etiologies of jaundice in adults.
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.
Findings and procedure details
Imaging Methods The methods used in evaluating the jaundiced patient currently include ultrasound (US),
computed tomography (CT),
magnetic resonance cholangiopancreatography (MRCP),
endoscopic retrograde cholangiopancreatography (ERCP),
and endoscopic US (EUS). Ultrasound US is the initial imaging test of choice in jaundiced patients because it is non-invasive,
inexpensive and readily available.
US is used to determine the presence of obstructive jaundice by depicting dilated bile ducts,
Ultrasound is a useful initial investigation of cholestatic jaundice because it is non-invasive and assesses pancreaticobiliary structures in real-time without exposing the patient to ionising radiation.
CT and MRCP are performed second line.
