The study aims to compare therapeutic outcomes, procedure-related complications, and recurrence rates in patients with stricturing small bowel Crohn's disease undergoing balloon-assisted enteroscopy-guided radial incision therapy. The results are expected to provide a novel and reliable treatment option for patients with stricturing Crohn's disease and to lay a foundation for improving disease-related symptoms and quality of life.",[73],"CD - Crohn's Disease",[75],"Crohn's Disease; balloon-assisted enteroscopy; stricture","NOT_YET_RECRUITING","2026-02-12",{"date":79,"type":80},"2026-02-13","ACTUAL",{"date":82,"type":67},"2026-03-01",{"date":84,"type":67},"2028-12-31",{"name":5,"class":6}]
