Surveillance colonosocpy for patient with Ulcerative ColitisCreated by:
Patient with ulcerative colitis are at an increased risk of colorectal cancer. Hence, interval surveillance colonoscopy is required in this cohort of patient. For patient with left sided colitis, the surveillance should begin after 15 years from the onset of disease. For patient with pan-colitis (affecting the whole colon), surveillance colonoscpy should start around 8 years after the diagnosis. There are some newer techniques like chromoendoscopy and narrow band imaging which will allow the endosocpist to have better visualization of the abnormal colonic mucosa, allowing for targeted colonic biopsies for the suspicious looking colonic mucosa. In the cohort of patient who has both ulcerative colitis and primary sclerosing cholangitis, surveillance colonoscopy should be done annually, due to high risk of colonic dysplasia in this cohort of patient.
