| [ Summary ] | Inflammatory bowel disease (IBD) is classified as ulcerative colitis (UC) and Crohn's disease. A severe complication of IBD is neoplasia in the small and large intestines in patients with IBD of long duration. Therefore, patients with IBD must undergo periodic surveillance for cancer. Patients with UC harbor many lesions with unclear borders in the inflamed mucosa. Initial lesions are mostly flat lesions and tend to occur synchronously or metachronously. Approximately 80 % of lesions occur in the rectum and sigmoid colon. Based on recognition of the characteristics of the initial lesions, clinical risk groups should be selected, and precise endoscopy using chromoendoscopy is necessary. | |
