What is this test?
This is a procedure in which X-ray imaging and contrast material help the clinician locate a stone in the common bile duct and guide its removal. Contrast makes the bile duct easier to see on images.
Why might I need this test?
It may be recommended when a stone is blocking the common bile duct and causing symptoms such as jaundice, abdominal pain, fever, nausea, or vomiting. Treatment may also be needed if the blockage increases the risk of infection or other complications.
How is the test performed?
A clinician inserts instruments through the digestive tract and uses imaging to identify the stone and remove it, sometimes by retrieving it or breaking it into smaller pieces. The procedure is usually performed with sedation or anesthesia, and the team uses X-rays to guide the instruments.
How do I prepare for the test?
Follow the care team's instructions about fasting, medications, and the timing of the procedure. Tell the clinician about kidney disease, previous contrast reactions, iodine or shellfish allergies, pregnancy, bleeding problems, and all medicines or supplements you use.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
The procedure may confirm the presence and location of a common bile duct stone and allow treatment of a blockage. Successful removal can restore bile flow and reduce the risk of infection or worsening symptoms. Temporary abdominal discomfort, nausea, or mild inflammation can occur, and the clinician should explain the procedure-specific risks.
