Fluoroscopy-Guided Endoscopic Retrograde Cholangiopancreatography (ERCP) with Contrast and Biliary Drainage
ERCP uses an endoscope and imaging guidance to examine the bile and pancreatic ducts, sometimes with contrast and drainage of the bile duct.

What is this test?
Endoscopic retrograde cholangiopancreatography, or ERCP, is a procedure that uses a thin, flexible scope to examine the ducts that drain the liver and pancreas. Contrast may be injected so the ducts can be seen on X-ray, and a drainage tube or stent may be placed if fluid or bile cannot pass freely.
Why might I need this test?
ERCP may be recommended when symptoms or imaging suggest a blockage, narrowing, or leak involving the bile or pancreatic ducts. It may be used to evaluate conditions such as jaundice, unexplained abdominal pain, or a suspected stone, and it can sometimes provide treatment during the same procedure.
How is the test performed?
You will usually receive sedation or anesthesia. The doctor passes the scope through your mouth and into the first part of the small intestine, then identifies the openings of the bile and pancreatic ducts. Contrast is used to outline the ducts, and a small tube or stent may be inserted to allow drainage.
How do I prepare for the test?
Follow the instructions from your care team, which may include fasting for several hours before the procedure. Tell the team about allergies, pregnancy, kidney problems, diabetes, implanted devices, and all medicines you take, especially blood thinners or diabetes medicines. Arrange transportation home because you may not be able to drive safely after sedation.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Abnormal findings may indicate a stone, narrowing, inflammation, leakage, or another blockage in the bile or pancreatic ducts. If drainage is needed, the procedure may help relieve pressure or jaundice while the underlying problem is evaluated or treated. Your care team will interpret the findings together with your symptoms, examination, and other imaging.
