| [ Summary ] |
Chromoendoscopy or narrow band imaging (NBI) using magnifying endoscopy improves diagnosis for surveillance endoscopy in patients with inflammatory bowel disease (IBD). These techniques also improve not only detection but also characterization of colitis-associated cancer/dysplasia (CC/D). While anorectal lesion surveillance procedures have not been established for patients with Crohn's disease (CD), it is important to recognize the necessity of surveillance and the importance of precise observations during surveillance endoscopy. In general, panchromoendoscopy with indigo carmine dye spraying improves detection of CC/D in patients with ulcerative colitis. Pancolonic NBI will improve detection and initial characterization of CC/D. Detection methods that on the differences of surface pattern between background mucosa and CC/D is essential to improve surveillance colonoscopy in patients with ulcerative colitis (UC). |
