Colonoscopy and gastroscopy are widely accepted as the gold standards for
screening, surveillance, and diagnosis of GI diseases. However, endoscopy
technology has not changed signicantly in decades and misses still occur
1
. In a
tandem study using traditional forward viewing (TFV) endoscopes, Rex et al. found
they missed 24% of the adenomas in the rst colonoscopy. Since that landmark
study, other technologies have shown the miss rate for TFV to be 31%
2
.
In another multi-center tandem trial, the Fuse
™
endoscope system demonstrated
the miss rate on adenomas with TFV was 42%. Out of 88 patients, a total of 48
adenomas were observed. TFV identied 28 adenomas. Fuse observed an
additional 20 adenomas. This means an additional 71% more adenomas were
detected by Fuse that traditional forward viewing endoscopes missed
3
. Conversely,
when the patient received a colonoscopy with Fuse rst, followed by TFV, the
researchers had an adenoma miss rate of only 8%.

How was this achieved? Traditional endoscopes typically
provide no more than a 140°-170° eld of view. Fuse Full
Spectrum Endoscopy provides a much greater eld of view
(330° Colonoscope / 245° Gastroscope), allowing the
endoscopist to see nearly twice as much anatomy as
traditional endoscopes.
