Endoscopic retrograde cholangiopancreatography (ERCP) is a procedure used to identify stones, tumors, or narrowing in the bile ducts. The procedure is done through an endoscope.

Alternative Names

Endoscopic retrograde cholangiopancreatography

How the test is performed

An intravenous (IV) line is placed in your arm. You will lie on your stomach or on your left side for the test. Medicines to sedate you will be given through the IV. Sometimes a spray to numb the throat is also used.

After the sedative takes effect, the endoscope is inserted through the mouth into the duodenum (the portion of the small intestine that is closest to the stomach).

A catheter (thin tube) is advanced through the endoscope and inserted into the pancreatic or biliary ducts. A special dye is injected into these ducts, and x-rays are taken to evaluate them. Narrowing, stones, and tumors can be identified.

Special instruments can be placed through the endoscope and into the ducts to open the entry of the ducts into the bowel, stretch out narrow segments, remove or crush stones, take tissue samples, and drain obstructed areas.

How to prepare for the test

You will need to fast at least 4 hours before the test and sign a consent form. Remove all jewelry so that it will not interfere with the x-ray.
