Advanced endoscopic imaging including high-definition endoscopy, confocal laser endomicroscopy (CLE) and endocytoscopy (EC) serve as an adjunct to predict clinical outcomes in inflammatory bowel disease (IBD). CLE can identify gut barrier dysfunction which correlates with disease behavior and long-term disease outcome. EC allows the assessment of histologic activity. Future controlled studies are warranted to define a definite role of these novel technologies in the management of patients with IBD.
