Objectives:Small bowel involvement in Crohn disease (CD) is clinically important for diagnosis and treatment. Single and double-balloon enteroscopy have already become important diagnostic tools in such cases. The on-demand NaviAid AB device enables deep advancement into the small bowel, using an anterograde or retrograde approach. In adults, this procedure is feasible, safe, and rapid. This work aimed to assess the safety and feasibility of NaviAid AB enteroscopy in pediatric patients.Methods:Single-center, prospective study using the through-the-scope balloon-assisted-enteroscopy (TTS-BAE) NaviAid AB device for the evaluation of the small bowel in children with suspected or known inflammatory bowel disease (IBD). The system consists of a single-use balloon catheter inserted through the instrument channel of a standard colonoscope. It consists of an inflation/deflation system (NaviAid SPARK), which is inflated to anchoring pressure. The repetitive push-pull technique enables the advancement of the colonoscope along the small intestine.Results:Fifty analyzed endoscopic procedures (30 retrograde, 20 anterograde) were performed in 34 children (52.9% boys, mean age 13.7 years). Average maximal depth of insertion (MDI), advancement depth using the NaviAid AB and average total procedure time were 138 cm (range 100-190 cm), 81 cm (range 40-120 cm), and 12.8 minutes (range 7.3-19.0 minutes), respectively, for the anterograde approach and 143 cm (range 100-170 cm), 64 cm (range 20-95 cm), and 21.9 minutes (range 13.9-32.0 minutes), respectively, for the retrograde approach. No serious or device-related adverse events were reported.Conclusions:NaviAid AB enteroscopy in children is safe, feasible, and enables assessment of the small intestine in a short period of time.
