Understanding Enteroscopy

What Is Enteroscopy?

Enteroscopy is a procedure that helps your doctor find and treat problems in the digestive system. During an enteroscopy, your doctor inserts a thin, flexible tube with an attached camera into your body. This is called an endoscope. There are usually one or two balloons attached to the endoscope. The balloons can be inflated to help your doctor get a closer view of your esophagus, stomach, and a section of the small intestine. Your doctor may use forceps or scissors on the endoscope to remove a tissue sample for analysis.

The two types of enteroscopy are upper and lower.

What preparation is required?

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 happens during an Enteroscopy?

In an upper enteroscopy, the endoscope is inserted into the mouth. In a lower enteroscopy, the endoscope is inserted into the 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 procedure, you might experience some mild side effects. These include:

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

What are possible complications of an Enteroscopy?

In rare cases, people may have complications after an enteroscopy procedure. 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’re experiencing:

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