[ Summary ] |
The efficacy of surveillance colonoscopy, using NBI for patients with ulcerative colitis (UC) is described. The entire colon was observed using NBI after insertion into the cecum. NBI may indirectly provide pit pattern diagnosis for UC associated cancer or dysplasia (CC / D). The accuracy of CC / D detection was equal to surveillance colonoscopy, using NBI (NBI-SC) or surveillance colonoscopy, employing conventional magnifying chromoendoscopy (CHR-SC). The major difference was in the total surveillance time for colonoscopy. NBI-SC could quickly and easily change NBI observation and conventional observation. NBI-SC has efficacy similar to CHR-SC, and is a very useful and time saving procedure for detection of CC / D in UC patients. NBI-SC will become popular, especially for surveillance colonoscopy, providing convenient optical pancolonic chromoendoscopy. |
