Endoscopic Retrograde Cholangiopancreatography (ERCP): What Is It?

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a procedure to diagnose and treat diseases of the bile duct system. Bile ducts are small tubes that carries bile produced by the liver into the intestines to aid digestion.

ERCP uses a combination of X-ray and an endoscope – a long, flexible tube with a tiny camera at the tip. The procedure is performed by a doctor with training in advanced endoscopic techniques. ERCP is done under sedation to minimise patient’s discomfort.

What Are the Indications for ERCP?

Gastroenterologists commonly use ERCP to diagnose and treat the following conditions:

  • Bile duct stones
  • Bile duct infections
  • Bile duct strictures ( ie narrowings )
  • Bile leaks eg after surgery

ERCP Procedure: Before, During & After

How to Prepare for ERCP?

Before the procedure, you should:

  • Fast for 6 hours.
  • Let your gastroenterologist know about any medications and supplements you take on a daily basis especially any blood thinners eg aspirin.
  • Inform your gastroenterologist about any special medical conditions you have, such as pregnancy, diabetes, lung and heart conditions, or allergies to any medications.
  • Ask someone to accompany you on your way home after the procedure, as you may feel drowsy after taking a sedative.

Depending on each individual case, Dr Koo and his team will walk you through a detailed plan for your ERCP preparation.

What Happens During ERCP?

ERCP is typically performed on an in-patient basis, with an overnight stay for observation after procedure. ERCP may take 1-2 hours. Sedation will be administered intravenously before the procedure begins.

During an ERCP,  the endoscope is inserted via the mouth to the ampulla ( opening of the bile duct ), which is located in the duodenum (the upper part of the small intestine). Instruments can then be inserted into the bile duct and a dye injected to highlight the biliary system and make it more visible on X-rays.

Once the problem is identified, your gastroenterologist may perform one of the following treatments:

  • Stent placement. A stent is a hollow tube that is placed to open blocked or narrow ducts.
  • Stone(s) removal. ERCP is a typical procedure of choice for the removal of common bile duct stones. Large stones will need to be broken down first before they can be safely removed.
  • Biopsy. During an ERCP,  abnormal tissue samples may be taken for further investigation.

What to Expect Afterwards?

Once the ERCP is completed, you will be brought to a recovery room where you will be observed until the sedation wears off. This will be followed by an over-night stay for continued monitoring of any complications.

Ideally, someone should accompany you on your way home. Since sedatives affect coordination and judgement, you should avoid driving and operating machinery for at least 8 hours.

You may experience some soreness in your throat, bloating and cramping after the procedure. This is common and should go away within 1-2 days.
