Endoscopic retrograde cholangiopancreatography (ERCP) is used to treat and diagnose problems in the liver, gallbladder, bile ducts, and pancreas. ERCP uses endoscopy and x-rays. An endoscopy is the use of a special scope with a camera to view your throat, stomach, and upper intestine.
This procedure may be done if you are suspected of having:
Complications are rare, but no procedure is completely free of risk. If you are planning to have an ERCP, your doctor will review a list of possible complications, which may include:
Some factors that may increase the risk of complications include:
Talk to your doctor about your medications. You may be asked to stop taking some medications up to one week before the procedure, like:
You will lie on your stomach with your head turned to the right. A mouthpiece will be placed in your mouth to help keep it open. Your breathing and heart rate will be monitored. An endoscope will be put into your mouth. The scope will be slowly passed through your throat into your esophagus, stomach, and/or small intestine/duodenum. Air will be passed through the scope to open the small intestine/duodenum to see better.
The images will be viewed on a video monitor. The scope will be passed into the place where the ducts from the liver and pancreas open into the small intestine.
A tiny tube from the endoscope will then be passed into the opening of the bile and pancreatic ducts. A contrast material will be injected through this tube. The contrast will make the ducts visible on the x-ray. If a gallstone shows up on the images, it may be removed through the scope. Scarring or narrowing within the ducts can also be treated with instruments passed through the scope. Stents may be placed to keep the duct open. Tissue samples may also be taken through the scope for biopsy. The sample will be sent to a lab for further testing.
It will take 30 minutes to two hours.
During the procedure, you may feel discomfort in your throat. After the procedure, your throat may be sore for a few days. In addition, you may feel bloated and need to belch.
If the ERCP is diagnostic, you may go home the same day. If you have other procedures done through the scope, you may need to stay in the hospital overnight.
You will be observed in a recovery area for at least one hour before you are sent home.
Be sure to follow your doctor's
