Procedure (Digestive System)
is the test?
endoscopy is a noninvasive technology that enables physicians to “see” the
entire twenty-one-foot length of the small intestine. The capsule endoscope is
a large pill containing a color camera chip, a wide-angle lens, illumination,
and a radio transmitter. The patient takes the pill with a large glass of water
and for the next eight hours the camera snaps two images per second as the
capsule works its way through the digestive tract. Capsule endoscopy helps
identify diseases of the small intestine (such as obscure bleeding, irritable
bowel syndrome, Crohn’s disease, chronic diarrhea,
and small bowel cancer), which are typically difficult to diagnose using
traditional imaging or endoscopic technologies.
How do I prepare?
You may consume nothing after midnight on the night before
the procedure. Some patients may be given a laxative to take, as well.
What can I expect during the procedure?
You will be asked to check in early in the morning at Outpatient
Registration. Once you arrive in the Endoscopy Department, a nurse will greet
you, take your health history and blood pressure, and answer any questions you
have about the exam. You will be given the capsule to swallow with a glass of
water. The nurse will attach an 8-lead sensor array, which is a group of
taped-on latex-free sensors that are placed strategically around your abdomen
to record signaled images from the capsule. The sensory array looks very much
like EKG patches. You will also be asked to wear a data recorder on an
adjustable belt that goes around your waist, which receives and stores images
as you go about your day. Before leaving the Endoscopy Department, the nurse
will give you instructions including dietary restrictions and activity
You will return to the Endoscopy Department eight hours later and your nurse
will remove the sensors and the data recorder. The capsule will continue to
travel through the intestines, to be expelled during a bowel movement and
How and when will I get my test results?
The transmitter delivers over 50,000 images during the 8-hour procedure.
These images are downloaded into a computer so that your gastroenterologist can
review them. Test results from capsule endoscopy are generally available within
a week. The gastroenterologist will notify you with the findings and will also
send a copy of the report to your primary care physician.
