may benefit from a new medical device that allows physicians to
view the entire length of the small intestine using a tiny camera
compact enough to be contained in an easily swallowed capsule,
but sensitive enough to offer a major improvement over existing
Digestive Center of Excellence has begun using the M2A capsule
that views the entire length of the small intestine, an advancement
over the traditional push enteroscope that examines only the top
evaluations suggest that this new technology may be 70 percent
more sensitive than traditional enteroscopy for the detection
of small-bowel abnormalities and may provide 12 times the diagnostic
ability of a radiologic series or X-rays, according to the journal
Gastroenterology and Endoscopy News.
camera has the potential to revolutionize the way we diagnose
intestinal bleeding, said Dr. Fabio Cominelli, an internal
medicine professor and director of the digestive center.
Given Diagnostic Imaging System, developed by Given Imaging of
Israel, consists of the video capsule, a data recorder and a processing
workstation. The capsule, the size of a large multi-vitamin pill,
contains a tiny disposable color video camera and transmitter,
which passes through the digestive tract and is excreted naturally.
The camera transmits two images per second to the data recorder
that patients wear around the waist as they continue their daily
about eight hours, the patient returns to the clinic, where the
data is downloaded into the workstation for the physician to evaluate.
U.S. Food and Drug Administration approved the Given system in
August. The FDA noted in a trial of 20 patients, the system detected
abnormalities in 60 percent of patients, compared to the 35 percent
detection rate of traditional enteroscopy. The FDA also noted
that this system identified sources of bleeding in five cases
that were beyond the reach of the enteroscope. All patients in
the trial had suspected small intestine disorders and had previously
undergone multiple gastrointestinal endoscopies and radiological
procedures to identify the source of their small intestine disorders,
without a conclusive diagnosis.
