Objective evaluation for treat to target in Crohn’s disease

BackgroundCrohn’s disease (CD) is a chronic and destructive bowel disease; continued disease activity can lead to penetrating complications. With the recent advent of effective medications, the importance of using a treat-to-target approach to guide therapy is becoming important.MethodsIn this review, we reviewed the previous evidence for evaluating CD lesions.ResultsWe describe ileocolonoscopy’s role in assessing disease activity, as well as recent progress in modalities, such as balloon-assisted endoscopy, capsule endoscopy, magnetic resonance enterography, computed tomography enterography, and ultrasonography. Advances in modalities have changed CD assessment, with small-bowel involvement becoming more important.ConclusionsProper optimization is necessary in clinical practice.
