Endoscopic retrograde cholangiopancreatography (ERCP) is a test that allows the doctor to see the bile and pancreatic ducts. It is done with a flexible, lighted tube called an endoscope. X-rays are also used.
An endoscope will be put into the mouth. It will be passed through the stomach until it reaches the small intestine. Images will be seen on a nearby monitor. Air will be passed through the scope. This will help the doctor view the area. A tube will be passed through the endoscope and into the ducts. A contrast material will be injected through the tube. This will make it easier to see the ducts with an X-ray. X-rays will be taken.
If needed, tiny tools may be passed through the endoscope to open blocked or narrowed ducts or remove stones or a tumor. A biopsy may also be done.
The tools and scope will be removed.
How Long Will It Take?
It will take 30 minutes to 2 hours.
Will It Hurt?
Throat pain is common in the first few days. Medicine and home care can help.
Average Hospital Stay
Most people can go home the same day. If other procedures were done during ERCP, you may need to stay longer.
At the Care Center
The staff may give you pain medicine.
It will take the rest of the day to recover. A normal diet can be resumed when swallowing has returned to normal.
