Single Camera Colonoscopy (SCC)
Modern colonoscopes are high-quality instruments with outstanding optics and excellent handling characteristics.
However, they contain a single video camera with an angle of view ranging from 140° to 170°, and this limits their ability to see behind folds and flexures.
Clinical research has shown that:
- Standard colonoscopy misses at least 24% of adenomas 1-3 and 12% of large adenomas (≥1 cm).4-6
- Large adenomas progress to cancer at a rate of 2-5% per year.7
- 7% of colorectal cancers in the U.S. are “interval cancers,” occurring within a few years after a colonoscopy.8
- Over half of interval cancers in the U.S. (about 6,000/year) result from missed lesions – mostly large adenomas.8,9
- 2/3 of missed adenomas are hidden behind folds.4
The Third Eye Panoramic Device Offers a Solution
- Two side-viewing cameras supplement the colonoscope’s forward view to create a panoramic video image (approximately 330°) that reveals areas behind folds and flexures.
- The device works with all standard adult or pediatric colonoscopes from the three major manufacturers, so endoscopists can continue using the scopes that they prefer.
- It maintains a free working channel to allow passage of instruments for polypectomy and to maximize suctioning of fluid and debris.
- The Third Eye Panoramic device was cleared by the FDA for marketing in the U.S. in November 2014.
How It Works
The Third Eye Panoramic device is placed on the distal tip of the colonoscope prior to beginning the procedure. The examination technique is identical to standard colonoscopy except that the endoscopist has a panoramic view of the colon throughout insertion and withdrawal.
The proximal end of the Third Eye Panoramic device plugs into a video processing unit that enables the left, middle and right images to be viewed on a single flat panel video monitor.
The Third Eye Panoramic device can be used with standard colonoscopes manufactured by Olympus, Pentax and Fujinon in both adult and pediatric sizes.
See Instructions for Use packaged with product for detailed operating instructions.
Low Cost, Multi-Use Device Enhances Quality
The latest version of the Third Eye Panoramic is resposable, meaning that it can be used multiple times prior to disposal. Thus, the resposable device provides an ultra-wide-angle view of the colon at low cost per procedure. The cleaning and disinfection protocols for the Third Eye Panoramic are similar to the methods used to reprocess colonoscopes between uses.
0:00 – Scope is in the cecum, with ileocecal valve in left-side view.
0:05 – NBI is activated on colonoscope, with no interference from laterally-directed LEDs.
0:10 – Withdrawing through distal ascending colon
0:16 – A polyp appears in the right-side view. Although not initially seen in the colonoscope’s view, once the endoscopist is aware of its existence, he is able to deflect the colonoscope’s tip up and to the right to bring the polyp into view at 0:36.
0:40 – Withdrawing through the sigmoid, the colonoscope naturally tracks around the outer curve of a flexure, leaving a “blind spot” in the inner curve distal to the flexure. The endoscopist uses the left lateral camera to view the area behind the flexure and folds.
0:56 – In another flexure, the left lateral camera again shows the inner curve and the area behind it.
