Abstract
In 143 jaundiced patients, ultrasound demonstrated the extrahepatic biliary system in 38% of those with medical and 74% of those with surgical jaundice. The size of the extrahepatic biliary system indicated that surgical was best differentiated from medical jaundice when 5 mm served as the upper normal limit for the common hepatic or common bile duct in patients without prior biliary surgery. Half of those patients with prior biliary bypass surgery had nondiagnostic sonograms. In 22% of the jaundiced patients, no additional imaging procedures were performed before definitive therapy. The role of ultrasound in evaluating jaundiced patients is discussed.Keywords
