Choledocholithiasis, a common abdominal condition, refers to the presence of gallstones within the common bile duct. These stones can originate in the gallbladder and migrate, or form directly in the duct, leading to bile flow obstruction, inflammation, and potential complications like cholangitis or pancreatitis. Ultrasound is a primary diagnostic tool, often revealing dilated bile ducts and directly visualizing the stones.
In medical ultrasound, identifying choledocholithiasis is crucial for timely intervention. Sonographic findings, including echogenic foci within the common bile duct with posterior shadowing and ductal dilation, guide clinical management. This abdominal ultrasound plays a vital role in patient assessment, helping to differentiate from other causes of jaundice or abdominal pain, and informing treatment strategies.
