Bedside Intestinal Ultrasound Predicts Disease Severity and the Disease Distribution of Pediatric Patients With Inflammatory Bowel Disease: A Pilot Cross-sectional Study.

Increasing bowel wall thickness (BWT) is associated with increasing IBD endoscopic scores on colonoscopy. There is moderate to fair agreement between the prediction of IBD diagnosis and Paris classification using intestinal ultrasound (IUS). Bowel wall thickness cutoff values to detect inflamed bowel segments are likely lower for children with IBD than for adults, although further studies with wider age ranges are needed to confirm this finding.
