Ileocolonoscopy is a highly sensitive and specific tool in the diagnosis and management of patients with suspected or already established IBD. This procedure is useful in obtaining biopsy tissue, which helps in the differentiation of other diseases, in the evaluation of mass lesions, and in the performance of cancer surveillance.

Colonoscopy also enables dilation of fibrotic strictures in patients with long-standing disease and has been used in the assessment of mucosal healing. In addition, it may be used in the postoperative period to evaluate surgical anastomoses as a means of predicting the likelihood of clinical relapse as well as the response to postoperative therapy.
