Capsule camera offers alternative for GI diagnoses
By Kathi Ovnic
The latest technology to detect trouble in the small intestine is now
available at the VA Hospital.
In the past, doctors have had difficulty diagnosing problems in the small
intestine because they only were able to see about one-third of it by
using the traditional entero-scopy, an uncomfortable procedure requiring
manual insertion of a scope into the small intestine via the mouth. Now,
with the help of a capsule-sized camera, doctors can obtain images of
the entire small intestine with little or no discomfort to the patient.
Recently approved by the Food and Drug Administration, the technology
was developed by Given Imaging, headquartered in Norcross. The patient
simply swallows a small capsule containing a camera that transmits video
images through radio frequency to a small recorder worn on a belt. As
the capsule moves through the small intestine, the camera transmits pictures
at the rate of two or three images per second, which are collected over
a six-to-eight-hour period. The pictures are then downloaded to a computer
The end result is images that give doctors an inside look at what is
happening with patients who are suffering from gastrointestinal (GI) problems
such as obscure chronic blood loss or iron-deficiency anemia. The camera
also can be useful in identifying inflammatory bowel disease and in helping
doctors distinguish between ulcerative colitis and Crohns Disease.
We are very excited about this product because we have been so
limited in the past in attempting to diagnose small bowel problems such
as obscure bleeding, said Peter Bloom, chief of the GI section at
the VA Hospital and assistant professor of medicine at the School of Medicine.
The quality of the images we are viewing in this area of the intestine
is unprecedented. The capsule is safe and easy for the patient to tolerate,
and it has the huge advantage of allowing the patient to go about his
or her normal daily routine.
While the capsule is not expected to replace colon-oscopypresently
it is designed for use in the small intestine rather than the large intestine,
through which it does not move as smoothlyBloom and his team plan
further studies to find other diagnostic uses.
The VA Hospital is the first site in the Southeast to offer this diagnostic
procedure. The procedure will soon be available through Emory Healthcare.
