Approach to a patient
with jaundice
Dr Ali Tumi
Jaundice
• Yellow discoloration of skin & sclera due to
excess serum bilirubin. >40umol/l,
(3mg/dl)
• Conjugated & Unconjugated types
• Obstructive & Non Obstructive (clinical)
• Pre-Hepatic, Hepatic & Post Hepatic
types
• Jaundice - Not necessarily liver disease *
Bilirubin
Metabolism
•Blood
•Conjugated &
Unconjugated
•Urine – Urobilinogen
•Stool – Stercobilin
Common Causes of Jaundice
• Pre Hepatic (Acholuric) - Hemolytic
– Unconjugated/Indirect Bil, pale urine
• Hepatic – Viral, alcohol, toxins, drugs
– Liver damage - unconjugated
– Swelling, canalicular obstruction Conjugated
• Post Hepatic (Obstructive) – Stone,
tumor
– Conjugated/Direct Bil, High colored urine,
Critical Questions in the Evaluation
of the Jaundiced Patient
• Acute vs. Chronic Liver Disease
• Hepatocellular vs. Cholestatic
– Biliary Obstruction vs. Intrahepatic Cholestasis
• Fever
– Could the patient have ascending cholangitis?
• Encephalopathy
– Could the patient have fulminant hepatic failure?

Evaluation of the Jaundiced Patient
• Ultrasound:
– More sensitive than CT for gallbladder stones
– Equally sensitive for dilated ducts
– Portable, cheap, no radiation, no IV contrast
• CT:
– Better imaging of the pancreas and abdomen
• MRCP:
– Imaging of biliary tree comparable to ERCP
• ERCP:
– Therapeutic intervention for stones
– Brushing and biopsy for malignancy
