Surveillance for Colorectal Neoplasia in Inflammatory Bowel Disease: When to Stop

Patients with chronic ulcerative and Crohn's colitis are at increased risk for colorectal neoplasia(CRN [dysplasia and cancer]) compared to the general population. Risk factors for CRN include extent of colitis, cumulative inflammatory burden, family history of colorectal cancer, and primary sclerosing cholangitis. Best practices to prevent CRN include control of colonic inflammation, high quality surveillance colonoscopy with or without enhanced imaging techniques, resection of visible dysplasia if possible, and colectomy in patients with unresectable dysplasia, invisible multifocal low grade dysplasia, or invisible high grade dysplasia. Cessation of dysplasia surveillance is individualized and should involve shared decision making based on factors including but not limited to chronologic age, frailty, co-morbid conditions, life expectancy, results of prior surveillance exams, and risk factors for CRN.
