Early intestinal ultrasound findings predict remission and treatment response at 1 year in pediatric Crohn’s disease

IUS correlated strongly with endoscopy in pediatric Crohn's disease over 1 year, with increased BWT being associated with a higher risk of ileocecal resection and not achieving remission. Thickened (inflamed) bowel became significantly thinner as soon as 1 month. BWT in pediatric patients in remission was significantly lower (≤2.5 mm) than in adults (≤3-4 mm).
