October 25, 2010 - Olympus Medical Systems Corporation and
Siemens Healthcare developed a new technology for stomach
examinations that allows comfortable patient procedures. The
patient swallows a capsule that is navigated via a joystick and a
magnetic field through the stomach. The capsule wirelessly
transmits images from inside the stomach to an image
processing system where the doctor can view the images. The
results of the first feasibility study published in the journal
“Endoscopy” show that this innovative new method functions
feasible and sufficiently accurate. A conceptual model of the
technology is introduced to the public for the first time at the
Olympus booth at the United European Gastroenterology Week
(UEGW) in Barcelona (October 23 – 27).
The prototype of the magnetically guided capsule endoscope (MGCE)
system was jointly developed by Olympus and Siemens and consists of an
innovative guidance magnet, an image processing and guidance information
system as well as the capsule endoscope. The patient swallows the capsule
together with water. The patient is positioned in the system so that his
stomach including the capsule is located in the center of an artificially
generated magnetic field. The magnet generates varying magnetic fields in
real time to navigate the capsule. The magnetic field enables the physician
to control the capsule with a joystick. The cameras at both ends of the
capsule transmit images from inside the stomach to the image processing
system where the doctor can view the images. The capsule endoscope is
approximately 31 mm long and measuring 11 mm in diameter.
A feasibility study of the magnetically guided capsule system (MGCE) has
been performed at the renowned Institute Arnault Tzanck in Saint Laurent du
Var (France) by Dr. Jean-Francois Rey and his colleagues H. Ogata, N.
Hosoe, K. Ohtsuka, N. Ogata, K. Ikeda, H. Aihara, I. Pangtay, T. Hibi, S.
Kudo and H. Tajiri. The study was published by the journal “Endoscopy”1 and
showed that the new technology appears to be feasible and sufficiently
accurate for gastric examination and may permit endoscopic examinations
that are more patient-friendly and without sedation. In a study with more than
50 people, 30 findings were detected in the stomach. Fourteen of the 30
findings were detected with both the capsule and the conventional
endoscope. Ten out of 30 were located with the capsule examination only
and six with the conventional endoscope only.
“The magnetically guided capsule system provides reliable results for
gastrointestinal endoscopic examinations compared to conventional
endoscopy. The capsule enables much less invasive stomach examinations.
It means an enormous boost in acceptability for the patient “, concluded Dr.
Jean-Francois Rey with respect to the feasibility study. The study
participants were equally enthusiastic: 93% thought the examination
comfortable, 89% found it easy to swallow the capsule, and regarding future
examinations, all patients questioned preferred the magnetically guided
capsule endoscope over conventional gastrointestinal endoscopy.
At UEGW, Dr. Rey presented the results of the first study. In a study entitled
“First Feasibility Study of Stomach Exploration with a Guided Capsule
Endoscopy”, Dr. Keiichi Ikeda, the Jikei University, Tokyo, Japan, will also
report his research results in Barcelona.
The product mentioned here is not commercially available. Due to regulatory reasons the
future availability in any country cannot be guaranteed. Further details are available from the
local Siemens organizations.
The outcomes achieved by the Siemens customers described herein were achieved in the
customer's unique setting. Since there is no "typical" hospital and many variables exist (e.g.,
hospital size, case mix, level of IT adoption) there can be no guarantee that others will
achieve the same results.
