Endoscopic retrograde cholangio pancreatography (ERCP) - series

ERCP

ERCP

Gallbladder endoscopy

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

Endoscopic retrograde cholangiopancreatography

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. The 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 special dye 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 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.

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:

• Infant test or procedure preparation (birth to 1 year)
• Toddler test or procedure preparation (1 to 3 years)
• Preschooler test or procedure preparation (3 to 6 years)
• Schoolage test or procedure preparation (6 to 12 years)
• Adolescent test or procedure preparation (12 to 18 years)

Because of the intravenous sedation, you may not feel any discomfort, and may have no memory of the test. There may be some gagging as the tube is passed down the esophagus. As the scope is positioned, there will be some stretching of the stomach and duodenum. Occasionally, stretching of the ducts can be felt.
