What Is Choledocholithiasis?
8. Diagnosis
If a doctor suspects a case of choledocholithiasis then they will likely want to request some tests. These tests are largely aimed at trying to identify gallstones in the bile duct. The tests will typically include a transabdominal ultrasound that will help to provide an image of the bile duct, as well as other organs and tissues in the area.
Endoscopic retrograde cholangiography is another test that can help find gallstones, and an endoscopic ultrasound is another potential method. A type of X-ray known as a percutaneous transhepatic cholangiogram will sometimes be used, as will a type of MRI known as a magnetic resonance cholangiopancreatography. Abdominal CT scans are another method that can be used.
