High-Grade Dysplasia in Inflammatory Bowel Disease: Indication for Colectomy.

Background: Patients with inflammatory bowel disease have an increased risk of colorectal cancer and are recommended to undergo increased surveillance compared to the general population. Currently, inadequate evidence exists to guide management of colonic dysplasia discovered during screening of inflammatory bowel disease patients.

Objective: The goal of this study was to determine the risk of colorectal cancer in patients with ulcerative colitis or Crohn's disease with dysplasia on colonoscopy.
