What is ERCP? 

Endoscopic retrograde cholangiopancreatography (ERCP) is an exam done to look at your bile or pancreatic duct. It can help to diagnose problems of the pancreas, bile ducts, liver, and gall bladder. 

How is an ERCP done?

During the exam, a tube is passed through your mouth, esophagus (the tube that connects the throat to the stomach), stomach, and the first part of the small bowel. Once in place, a small plastic tube is threaded into the ducts, a dye is injected, and x-ray pictures are taken.

Treatment can also be done at this time. Treatments allow us to:

  • Enlarge the bile duct opening.

  • Remove gallstones lodged in the bile duct.

  • Place a stent (drain) in the duct.

  • Take a biopsy.

  4. Our staff will need to review your health history. This includes any past surgeries, allergies, and medicines that you take. Please bring this information with you.

The Day of Your ERCP

  1. You are not able to have any solid food, milk or dairy products.

  2. You may drink clear liquids until 4 hours before you arrive (i.e. water, apple juice, soda, Gatorade®). This is done to keep you safe. Do not drink red liquids

  3. Take your normal medicines with a small sip of clear liquid up to 1 hour before you arrive. Do not take medicines mentioned under the “Important to Know” section.

  4. Follow the instructions in your cover letter. If you are running late, call us at (608) 263-8094 to let us know. If you are more than 30 minutes late, we may have to cancel and reschedule. We do our best to stay on time.

  5. Plan to be with us about 3-5 hours. Your driver will need to be available in our waiting room or by phone.

The Test

A nurse will review your health history and place an IV. The IV is used to give you medicines which make you feel drowsy and relaxed during your test. You will be placed on an x-ray table and will lie on your stomach for the exam. If there is a chance that you are pregnant, we will need to know this before using the x-ray machine. The test will take about 1 hour.

After the test you will go to our recovery room for about 1½ hours. Your driver may sit with you there. Once awake, you may be given something to drink. Sometimes patients will need to stay in the hospital for the night. 

Your doctor will discuss results with you before you go home. You and the doctor who referred you will get a copy of the report.

After the Exam and for the Rest of the Day

  • Do not return to work.

  • Do not drive.

  • Do not use heavy machinery.

  • Do not make any important decisions.

  • Plan to rest.

  • Do not drink alcohol. 

  • You should be able to resume normal daily tasks the day after your exam.

  • You may have a mild sore throat. Gargling salt water should help.

  • You will be asked to stay on a liquid diet for the rest of the day.

  • You may have some gas pains from the air used to distend your stomach. Belching will help.
