Ultrasound remission after biologic induction and long-term endoscopic remission in Crohn's disease: a prospective cohort study

The Bowel Ultrasound Score (BUSS) accurately detects therapy-related changes by using the Simple Endoscopic Score for Crohn's disease (SES-CD) as the reference standard. We aimed to evaluate ultrasound remission as a treatment target and its prediction for long-term endoscopic remission.
