Endoscopic Surveillance in Inflammatory Bowel Disease.

Introduction: Endoscopy is a key technique for the surveillance of patients with inflammatory bowel diseases (Crohn's disease (CD) and ulcerative colitis). Indication to perform endoscopy for surveillance includes assessment of response to therapy, postoperative surveillance, and surveillance for intraepithelial neoplasia.

Methods: In addition to personal experience, a literature search was performed and the guidelines were consulted.

Results and Conclusion: Endoscopy is the gold standard in the long-term assessment of mucosal healing and in the short-term control of response to intensified therapy. For postoperative surveillance in CD, mucosal changes (as graded by the Rutgeerts score) are predictive of clinical recurrence. For neoplasia surveillance, virtual chromoendoscopy has not (yet) replaced conventional chromoendoscopy. Surveillance can be optimized by the use of high-definition endoscopes as well as (pan-)chromoendoscopy and requires time to scrutinize the mucosa. This approach seems to be superior to random biopsies.
