Background:
Research data on balloon-assisted enteroscopy-guided stricturotomy (BAE-ES) versus endoscopic balloon dilation (BAE-EBD) for the treatment of Crohn's disease (CD)-related deep small intestinal strictures is limited. This study aimed to compare the efficacy and safety of BAE-ES versus BAE-EBD in treating CD-related deep small intestinal strictures.
Methods:
This retrospective study included patients with CD-related deep small intestinal strictures who underwent either BAE-ES or BAE-EBD treatment between May 2021 and June 2025. Outcome measures included technical success, adverse events, and follow-up outcomes.
Results:
A total of 100 CD patients underwent treatment (BAE-ES: n = 59; BAE-EBD: n = 41).
Bae-Es:
73 BAE-ES procedures were performed on 59 patients. The technical success rate was 98.63% (72/73). Immediate bleeding occurred at 15 stricture sites (20.55%) in 15 patients (25.42%).
Bae-Ebd:
44 BAE-EBD procedures were performed on 41 patients. The technical success rate was 88.64% (39/44). Immediate bleeding occurred at 21 stricture sites (47.73%) in 21 patients (51.22%).
Follow-Up:
BAE-ES: No cases of bleeding or perforation occurred during follow-up. 1 patient (1.69%) underwent partial small intestinal resection. Stricture recurrence requiring endoscopic re-intervention occurred at 2 sites (2.74%) in 1 patient.
Bae-Ebd:
Bleeding occurred in 2 patients during follow-up; no perforations occurred. Four patients (9.76%) underwent partial small intestinal resection. Stricture recurrence requiring endoscopic re-intervention occurred at 6 sites (13.64%) in 6 patients; the treatment strategy was changed to BAE-ES, which achieved technical success.
Conclusion:
BAE-ES demonstrates a higher technical success rate and favorable efficacy and safety profile for treating CD-related deep small intestinal strictures, warranting broader clinical application.

Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
