What Is ERCP Used For?

ERCP is primarily used to identify and address issues like blockages, strictures, or abnormalities in the bile or pancreatic ducts. It may also be used to remove stones, repair leaks, or place stents to improve drainage.

How Does ERCP Work?

During ERCP, a thin, flexible tube (endoscope) is inserted through your mouth into your digestive tract. A contrast dye is injected through the endoscope to visualize the bile and pancreatic ducts using X-ray imaging. A doctor can then perform procedures like stone removal or stent placement if needed.

Preparation for ERCP

You may need to fast for several hours before the procedure, depending on your doctor’s instructions. Medications to relax your throat or reduce saliva may also be given. Inform your doctor about any allergies or medications you’re taking.

What to Expect During ERCP

You’ll likely be sedated to stay comfortable during the procedure, which usually takes about 30 to 60 minutes. Afterward, you’ll need to rest for a few hours before going home. You may experience mild discomfort or bloating, but severe pain is uncommon.

Frequently asked questions

Why might your doctor order this test?
Your doctor may recommend ERCP to diagnose conditions like gallstones, pancreatic tumors, strictures, or bile duct blockages. It can also help evaluate symptoms such as abdominal pain, jaundice, or unexplained weight loss that may be linked to digestive issues.
How is ERCP different from a standard endoscopy?
Unlike a standard endoscopy, which only examines the upper digestive tract, ERCP includes specialized imaging to visualize the bile and pancreatic ducts. It also allows for direct intervention, such as removing stones or placing stents, during the procedure.
What are the risks or side effects of ERCP?
Common risks include mild discomfort, bleeding, or infection. Rarely, complications like pancreatitis or perforation of the bile or pancreatic ducts may occur. Your doctor will discuss risks and precautions before the procedure.
