| [ Summary ] |
It is widely known that surveillance for colorectal cancer is necessary for patients with ulcerative colitis (UC). The risk of colorectal cancer increases with the extent and duration of UC. Crohn's disease (CD) presents similar risks for UC with similar involvement and duration in the colorectum. The procedural techniques recommended for surveillance have changed from random biopsies to target biopsies. However, it is difficult to detect lesions associated with chronic mucosal inflammation. Magnification endoscopy is useful for distinguishing neoplasms from non-neoplasms in the colorectum. The usefulness of magnification endoscopy for surveillance of ulcerative colitis-associated colorectal cancer has also been reported. We conclude that magnification endoscopy can identify IBD associated cancer in cases of UC. |
