Development of a new classification system to assess mucosal healing in inflammatory bowel disease (ibd) using narrow band imaging (nbi) without optical magnification

NBI is based on optical filters narrowing the red light therefore highlighting the vascular pattern morphology of the luminal gastrointestinal tract. Assessment of vascular changes in IBD is of pivotal importance for prediction of mucosal healing and for guidance of pharmaceutical therapies. To date, only limited data is available on the use of NBI for assessment of mucosal healing in IBD.
