Colon capsule endoscopy compared with other modalities in the evaluation of pediatric Crohn’s disease of the small bowel and colon - 31/05/16
Abstract |
Background and Aims |
Data on colon capsule endoscopy (CCE) in evaluating the small bowel and colon concurrently are rare. This study aimed to evaluate the accuracy of CCE in assessing disease activity of the small bowel and colon in pediatric Crohn’s disease (CD) by comparison with magnetic resonance enterography (MRE), small-intestine contrast US (SICUS), and ileocolonoscopy.
Methods |
We prospectively enrolled 40 consecutive patients (22 male, 18 female, mean age 13.1 ± 3.1 years) with CD of the small bowel and colon. All underwent SICUS, MRE, CCE, and ileocolonoscopy sequentially over 5 days. All investigators were blinded to patient history and test results. Patients were classified as active or inactive for the small bowel and the colon according to specific criteria for each tool (simple endoscopic score for CD, Lewis score, US and magnetic resonance parameters of activity). For colon mucosa evaluation, ileocolonoscopy was the comparator. For the small bowel, a consensus panel was convened.
Results |
Sensitivity of CCE to detect colon inflammation was 89%, and specificity was 100%. The positive predictive value (PPV) and negative predictive value (NPV) of CCE for colon inflammation were 100% and 91%, respectively. In the small bowel, CCE showed 90% sensitivity, 94% specificity, with PPV and NPV of 95% and 90%, respectively. Accuracy parameters for SICUS (sensitivity 90%, specificity 83%) and MRE (sensitivity 85%, specificity 89%) were lower than those for CCE. No serious adverse events related to the CCE procedure or preparation were reported.
Conclusions |
CCE is of great usefulness in evaluating both small bowel and colon mucosa in pediatric CD. This single, noninvasive tool makes it possible to evaluate the small-bowel and the colon concurrently with high diagnostic accuracy. Future multicenter studies need to define the role of CCE in the routine management of pediatric patients with CD. (Clinical trial registration number: NCT02199626.)
