A Treat-to-target Strategy Using Pan-enteric Capsule Endoscopy (PCE) in Paediatric Crohn's Disease (CD).

This first prospective study on mucosal healing (MH) and deep remission (DR) in pediatric Crohn's Disease aims to evaluate: * The ability of Pan-enteric capsule endoscopy (PCE) to assess MH and DR rates at three time points and to guide a treat-to-target strategy was the primary outcome sought. * The efficacy of a "treat-to-target" strategy to MH and DR rates over 24 and 52 weeks was evaluated as a secondary outcome; * Comparison between PCE, biomarkers, Magnetic Resonance Enterography (MRE) and Small Intestine contrast ultrasonography (SICUS) in evaluating intestinal inflammation.
