An ERCP is a medical procedure that diagnoses and treats problems in the bile ducts and pancreatic ducts.
Endoscopic retrograde cholangiopancreatography (ERCP) uses a flexible scope and X-ray imaging to find and remove blockages.
This procedure combines endoscopy and fluoroscopy. Endoscopy uses a thin tube with a camera.
Fluoroscopy uses X-ray guidance. Together, they allow doctors to see inside the ducts and treat problems simultaneously.
ERCP is both a diagnostic and treatment procedure.
What Does an ERCP Do?
An ERCP examines and treats blockages in the bile ducts and pancreatic ducts. It can remove stones, open narrow ducts, and place stents.
Doctors use ERCP to:
- Remove bile duct stones
- Place stents in blocked ducts
- Open narrowed ducts (strictures)
- Take tissue samples (biopsy)
- Treat leaks in the bile ducts
Unlike imaging tests like MRCP, ERCP can treat the problem during the same session.
How Does an ERCP Work?
ERCP works by guiding a flexible scope through the mouth into the small intestine.
A small tube then injects contrast dye into the bile ducts. X-rays show detailed images of the ducts.
Here is how the procedure happens:
- The patient receives sedation.
- The doctor inserts the endoscope through the mouth.
- The scope passes through the stomach into the duodenum.
- A small catheter injects contrast dye into the ducts.
- X-rays capture images.
- Treatment is performed if needed.
The procedure usually takes 30 to 90 minutes.
Patients are sedated, so they do not feel pain during the procedure.
Why Is ERCP Performed?
Doctors perform ERCP when they suspect a blockage or damage in the bile or pancreatic ducts. It is usually recommended after imaging shows a problem.
Common reasons include:
- Jaundice (yellow skin and eyes)
- Bile duct stones
- Pancreatitis
- Tumors blocking the duct
- Bile duct strictures
- Abnormal liver blood tests
If a scan shows a stone in the common bile duct, ERCP can remove it right away.
Is ERCP Safe?
ERCP is safe for most people but has known risks.
Possible risks include:
- Pancreatitis
- Infection
- Bleeding
- Perforation (rare tear in the intestine)
- Reaction to sedation
Pancreatitis is the most common complication. It happens in about 3–10% of cases.
Doctors carefully evaluate risk before recommending ERCP.
Recovery
Recovery is usually quick, with same-day discharge.
After the procedure:
- You rest until sedation wears off.
- You avoid driving for 24 hours.
- You start with light food.
- You monitor for fever or severe pain.
If severe abdominal pain, fever, or vomiting occurs, medical care is needed right away.
Most people return to normal activity within 1–2 days.
Conditions Treated with ERCP
ERCP treats several conditions related to bile and pancreatic ducts.
Common conditions include:
- Common bile duct stones
- Bile duct obstruction
- Pancreatic duct blockage
- Tumors causing duct compression
- Bile leaks after surgery
In cancer cases, ERCP often places a stent to relieve blockage and reduce jaundice.
This helps improve quality of life and prevents infection.
Risks vs Benefits of ERCP
The benefit of ERCP is immediate treatment of duct problems. The risk is a small chance of complications.
Doctors recommend ERCP when:
- A blockage is confirmed
- Stones must be removed
- A stent is required
- Infection is present
The risk of not treating a blocked duct can be higher than the procedure risk.
Clear communication helps patients understand this balance.
Understanding ERCP and Your Treatment Options
An ERCP is a procedure that diagnoses and treats bile duct and pancreatic duct problems in one session.
It uses a scope and X-ray guidance to remove stones, open blockages, and place stents.
We use ERCP when imaging shows a problem that needs treatment. It is more invasive than a scan, but it provides direct solutions.
If your doctor recommends ERCP, it means treatment is needed, not just imaging.
With proper evaluation and skilled care, ERCP is an effective way to restore bile flow and protect your health.
