Intestinal Ultrasound in Pediatric Inflammatory Bowel Disease

Children diagnosed with either CD or UC will be enrolled at diagnosis or at any time point during follow-up. Patients' characteristics will be retrieved from their medical files including demographic details, disease phenotype, endoscopic and radiologic variables, anthropometric measures, laboratory evaluation, complication and therapeutic regimens. At enrollment and every 3 months for a total period of 2 years all patients will perform intestinal US during regular clinic visits. All other measures including laboratory exams, anthropometric measurements and disease activity indices (either PCDAI for CD or PUCAI for UC) will be performed as part of standard of care.
