How the test is performed:
This test is usually done in the hospital. The throat is sprayed with a local anesthetic. A sedative and pain killer are given through a vein. A special flexible tube (endoscope) is inserted through the mouth into the duodenum (the portion of the small intestine that is closest to the stomach). A catheter is advanced through the endoscope and inserted into the pancreatic or biliary ducts. A contrast agent is injected into these ducts and x-rays are taken to evaluate their caliber, length and course. Narrowing, stones, and tumors can be identified. Special instruments can be placed through the scope 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.
Infants and children:
The preparation you can provide for this test depends on your child's age, previous experiences, and level of trust. For general information regarding how you can prepare your child, see the following topics:
