What is video capsule endoscopy?
Video capsule endoscopy is a procedure that allows a doctor to
examine your small intestine for sources of bleeding. It may be especially
helpful for diagnosing
Crohn's disease.
How is it done?
For this procedure, you swallow a capsule that is less than an inch
long (about 23 mm). A technician attaches sensors to your chest and connects
them to a data recorder that you wear on a belt around your waist. The capsule
contains a tiny video camera. As the capsule travels through your
gastrointestinal tract, the camera takes pictures and sends them to the data
recorder. After 8 hours, the technician removes the data recorder and looks at
the pictures. The capsule passes out of your body in the stool within a day or
two.1, 2
What are the advantages?
Video capsule endoscopy is becoming popular because it has several
advantages over traditional endoscopy:
- It can show the entire small intestine and thus
may be better at finding sources of bleeding.
- It is not invasive.
In traditional endoscopy, a thin, lighted tube is inserted down your throat.
- It is painless, so you do not need to take pain medication.
- You do not have to stay in the hospital.
- You have to
fast for 12 hours before swallowing the capsule, but it does not require other
preparation.
When should it not be used?
Video capsule endoscopy is generally safe and well-tolerated. But
it should not be used if you are known to have intestinal obstructions or
narrowing (strictures) or abnormal connections or openings between two organs
or parts of the body (fistulae).
