Had ulcerative colitis for 15 yrs (confirmed by sigmoid and biopsies). just had 1st colonoscopy, shows granular, loss of vascular pattern and minor ulcers in ascending colon, cecum, sigmoid and colon. is this uc or chrons?

Ulcerative colitis: All of the biopsies from colonoscopy showed inflammatory changes consistent with ulcerative colitis. The later is part of the spectrum of IBD but involves only the mucosal layer of the bowel. Chrons disease is a form of IBD that involves all layers of the bowel and can be recognized on scans of the bowel or deeper layers of bowel on bx.
