 Enteroscopy

​​

We offer Enteroscopy at both our Credit Valley Hospital and Mississauga Hospital locations.

Enteroscopy is a test where a doctor inserts a thin, flexible tube with a miniature camera attached to it into your body. This is called an endoscope. There are usually one or two balloons attached to the endoscope. These balloons can be inflated to make it easier for the doctor to see inside you. This procedure allows the doctor to:

  • get a closer view of your esophagus, stomach, and a section of the small intestine
  • take a small piece of tissue so that it can be examined under a microscope (this is called a biopsy)

Enteroscopy can be used to:

find and treat problems in the digestive system

Referrals

A referral from a doctor is required.

How to Prepare for an Enteroscopy

Do NOT eat or drink after midnight the evening before the test. You need to have an empty stomach for the test. You may take your usual medications on the morning of the test with a sip of water only.

What to Expect During an Enteroscopy

If you are having an upper Enteroscopy, the endoscope will be inserted into your mouth. In a lower Enteroscopy, the endoscope is inserted into your rectum. The type of Enteroscopy performed will depend on the type of problem the doctor is trying to diagnose. Your doctor will let you know in advance which type you need.

What Happens After an Enteroscopy?

After the test, you might experience some mild side effects. These include:

  • a sore throat
  • abdominal bloating
  • nausea
  • minor bleeding
  • mild cramping

Are There Any Possible Complications?

In rare cases, people may have complications after an Enteroscopy. These include pancreatitis, internal bleeding, and tearing in the wall of the small intestine. Some people might also have an adverse reaction to the anesthesia. This is why Enteroscopy usually isn’t recommended for pregnant women, overweight people, or people with heart or lung disease.

Make sure to call your doctor immediately if you are experiencing:

  • more than a few tablespoons of blood in your stool
  • severe stomach pain
  • a firm, swollen stomach
  • a fever
  • vomiting
