Capsule Endoscopy

What is capsule endoscopy?

Capsule Endoscopy lets your doctor examine the lining of the middle part of your gastrointestinal tract, which includes the three portions of the small intestine (duodenum, jejunum, ileum). Your doctor will use a pill-sized video capsule-called an endoscope, which has its own lens and light source-to view the images on a video monitor. You might hear your doctor or other medical staff member refer to capsule endoscopy as small-bowel endoscopy, capsule-enteroscopy, or wireless endoscopy.

Why is capsule endoscopy done?

Capsule endoscopy helps your doctor evaluate the small intestine. This part of the bowel cannot be reached by traditional upper endoscopy or by colonoscopy. The most common reason for doing capsule endoscopy is to search for a cause of bleeding from the small intestine. It may also be useful for detecting polyps, inflammatory bowel disease (Crohn's disease), ulcers, and tumors of the small intestine. As it is in the case of most new diagnostic procedures, not all insurance companies currently reimburse for this procedure. You may need to check with your own insurance company to ensure that this is a covered benefit.

How should I prepare for the procedure?

An empty stomach allows for the best and safest examination, so you should have nothing to eat or drink, including water, for approximately 12 hours before the examination. Your doctor will tell you when to start fasting. Tell your doctor, in advance about all medications you take, including iron, aspirin, stomach coating products, and other "over- the-counter" medications. You might need to adjust your usual dose prior to the examination. Discuss any allergies to medications, and medical conditions, such as swallowing disorders and heart or lung disease, that you have. Tell your doctor if you...

• had previous abdominal surgery
• have a history of bowel obstructions, inflammatory bowel disease, or adhesions

What can I expect during capsule endoscopy?

Your doctor will prepare you for the examination by applying a sensor device to your abdomen, using adhesive sleeves, which are similar to strips of tape. You will swallow the capsule endoscope, which will transmit video images to a data recorder, while it passes naturally through your digestive tract. You do not need to recover the capsule once it passes. You will wear the recorder on your belt for approximately eight hours. At the end of the procedure, you will return to the office and the data recorder will be removed so that images of your small bowel can be put on a computer screen for the physician to review.
