Colonoscopy with a forward-viewing camera leaves regions that are not visualized in detail. Thus development of video-enoscopy systems with wide angle of view is needed. Full-spectrum colonoscopes providing image of Ultra HD 4K quality are now available in Russia. MATERIALS AND METHODS. Seventy patents were assessed with a full-spectrum colonoscope. In 51 (72,8°%) of them the procedure was performed also for physician's training purposes. Fifteen (21,4%) patients underwent simultaneous full-spectrum and forward-viewing colonoscopies, while in 4 (5,7%) full-spectrum endoscope was used to visualize lesions that were non-assessable with traditional equipment. RESULTS. Applying Jull-spectrum colonoscopy for diagnosis resulted in detecting 170 polyps in 51 patients (polyp detection rate was 47,1%). Simultaneous use of full-spectrum colonoscope after forward-viewing equipment led to 9 additional polyps detection in one patient and 23 additional polyps in another one. In 7 patents full-spectrum colonoscopy allowed detection of polyps that were not found via forward-viewing equipment. CONCLUSION. During full-spectrum colonoscopy inner colonic surface can be visualized with an angle of view of 330° which is twice more than video-capturing area ofa standard forward-viewing endoscope. The equipment allows to significantly increase adenoma detection rate.
