MINUTE FINDINGS DETECTED BY MAGNIFYING COLONOSCOPY IN ULCERATIVE COLITIS

In order to detect flat‐type dysplastic and cancerous lesions associated with longstanding ulcerative colitis, it is important to understand the minute findings detected by magnifying colonoscopy in active and quiescent stage of ulcerative colitis. The severity of mucosal findings by magnifying colonoscopy could be categorized as follows: polypoid mucosal tag which has severe ulceration and hemorrhage; coral‐reef‐like appearance which has coarse or nodular mucosa with ulcerations; minute defect of epithelia which has minute or shallow depressions surrounded by edematous mucosa; small yellowish spots which has minute whitish or yellowish coats; villi‐like appearance which has shaggy appearance like small intestinal villi; and regularly arranged crypt opening which has round shaped and regularly arranged crypt.
