Abdomen Sonography: Common Bile Duct Pathology - Video Lesson

Welcome back everyone. Today we'll shift our focus to the biliary system, specifically the common bile duct and related structures. Understanding the sonographic appearance of biliary disease is essential for both registry exams and clinical practice. The biliary tree plays a vital role in transporting bile from the liver and gallbladder into the duodenum. And when pathology occurs, patients often present with jaundice, abdominal pain, or abnormal lab values, such as elevated bilirubin, alkaline phosphatase, and gamma glutamyl transferase which is particularly helpful for confirming a hepatobiliary source of alkaline phosphatase elevation. The biliary system begins with the intrahepatic ducts that join to form the right and left hepatic ducts. These merge into the common hepatic duct, which then joins the cystic duct from the
