Strictures at this location are challenging to diagnose and out-of-reach of colonoscopy. We aimed to evaluate the detection rate of small bowel strictures with magnetic resonance enterography (MRE) and assess the efficacy of double-balloon enteroscopy-assisted endoscopic balloon dilatation (DBE-assisted EBD) in managing these strictures.\u0000Methods: A retrospective study included all patients with DBE-assisted EBD of small bowel strictures in CD in our facility. All patients had MRE to detect strictures prior to the dilatation. Sequential dilatation protocol was performed using through-the-scope (TTS) working channel balloons. The outcomes included technical success defined by the passage of the enteroscope post-dilatation, resolution of symptoms and the requirement of repeated procedures or surgery during 12 months of follow-up.\u0000Results: 20 DBE-assisted EBDs of small bowel strictures were attempted during 13 DBE procedures in 10 patients (6 males, median age 42). MRE identified 75% of the strictures with 100% accuracy in localisation. Retrograde DBE was the approach in 16/20 (80%) strictures. Anesthetic intubation was used in 8/20 (40%). DBE reached 19/20 strictures. All the reached strictures were dilated successfully; the technical success following dilatation was 72.2%. The median DBE insertion time with TTS balloon dilatation was 66 minutes. Three patients required follow-up dilatations within 2-3 months. Surgery was not needed during the follow-up period. \u0000Conclusions: MRE is essential in diagnosing and localising small bowel strictures in CD. DBE reached 95% of strictures with successful dilatation. Immediate technical success was high, and safety was demonstrated.
