Five studies, two single-balloon enteroscopy studies, two double-balloon enteroscopy studies, and one balloon-guided enteroscopy study evaluating the impact of balloon-assisted enteroscopy systems in children with established IBD, were conducted.

Capsule endoscopy (CE) and device-assisted enteroscopy (ESOG) have significantly expanded the diagnostic capabilities of small bowel diseases. Capsule endoscopy provides a noninvasive test for visualizing the entire small bowel mucosa, which may aid in the diagnosis of small bowel Crohn's disease and in monitoring response to treatment.

Endoscopic balloon dilation of small bowel strictures has an overall technical success rate of 72% to 100%, and a clinical success rate greater than 60%, although there is no standardized definition of either of these short-term outcomes.

Device-assisted small bowel endoscopy (device-assisted small bowel endoscopy) allows histological confirmation when conventional endoscopy, capsule endoscopy, and cross-sectional imaging are inconclusive and also allows therapeutic interventions such as balloon dilation of strictures, intraluminal steroid injections, capsule retrieval, and recently stent placement to resolve small bowel strictures.

Single balloon enteroscopy is usually performed by two endoscopists, but double balloon enteroscopy can be easier to perform with a single endoscopist. Enteroscope and overtube are advanced techniques similar to the insertion technique of double balloon enteroscopy.
