Capsule endoscopy

Info: Capsule endoscopy

Capsule endoscopy is a procedure that uses a tiny wireless camera to take pictures of your digestive tract. The camera sits inside a vitamin-sized capsule that you swallow. As the capsule travels through your digestive tract, the camera takes thousands of pictures that are transmitted to a recorder you wear on a belt around your waist or ov
er your shoulder.

Your doctor m
ay recommend capsule endoscopy to help diagnose or treat:

-->Obscure gastrointestinal bleeding. Capsule endoscopy can help find the cause of gastrointestinal bleeding.
-->Inflammatory bowel diseases. Capsule endoscopy may reveal areas of inflammation in the small intestine that can help your doctor diagnose Crohn's disease and other inflammatory bowel diseases.
-->Cancer. Capsule endoscopy can identify tumors in the small intestine that otherwise might be difficult to detect. Capsule endoscopy sometimes is done in conjunction with CT enterography because CT enterography can indicate tumors within the small bowel wall.
-->Celiac disease. Some small studies suggest that capsule endoscopy can detect intestinal changes associated with celiac disease — an immune reaction to eating gluten — and can help detect complications of the condition.
-->Polyps. People who have inherited polyposis syndromes that can cause polyps in the small intestine, such as Peutz-Jeghers syndrome, may occasionally have capsule endoscopy to screen for polyps.

How you prepare?
To prepare for capsule endoscopy, your doctor may ask that you:

Restrict your diet. You probably will be asked to have only clear liquids for 24 hours before the procedure and nothing by mouth the morning of the procedure, to help ensure that the camera captures clear images of your digestive tract.
Stop or delay taking certain medications, to prevent them from interfering with the camera.
Avoid strenuous exercise or heavy lifting after the procedure. You'll be able to do most normal activities after swallowing the capsule that contains the camera. But if you have an active job, ask your doctor whether you can go back to work on the day of your capsule endoscopy.
Failure to follow your doctor's instructions may mean having to reschedule your capsule endoscopy procedure.

After the capsule endoscopy:
You can generally go about your normal activities while the camera pill passes through your digestive tract. You may be asked to avoid repetitive movements that could disrupt the recorder.

Capsule endoscopy can be done with a camera that takes pictures for eight hours or 12 hours. Your doctor will tell you which type of capsule endoscopy you are having, and when you can resume eating and drinking.

The procedure is complete after eight or 12 hours or when you see the camera capsule in the toilet after a bowel movement. Remove the antenna patches and the recorder. Pack them in a bag and follow your doctor's instructions for returning the equipment.

You don't need to collect the camera capsule — it can be safely flushed down the toilet.

Your body may expel the camera capsule within hours, or it may be expelled after several days. Each person's digestive system is different. If you don't see the capsule in the toilet within two weeks, contact your doctor. An X-ray may be done to see if the capsule is still in your body.
