Long-Term Outcome of Endoscopic Balloon Dilatation for Strictures in Patients with Crohn's Disease.

BACKGROUND/AIMS: Endoscopic balloon dilatation (EBD) is an alternative to surgery for strictures in patients with Crohn's disease (CD). The aim of the present study was to clarify the efficacy and safety of EBD for strictures in patients with CD.

METHODS

Twenty-six patients with CD who underwent EBD for strictures from August 2008 to November 2015 were followed up after dilatation. Short-term success was defined as the disappearance of obstructive symptoms after technically adequate dilatation was achieved. The short-term success rate of EBD, safety profile of EBD, and cumulative surgery-free and redilatation-free rates were analyzed.

RESULTS

Sixty-five EBDs were performed for CD patients in the follow-up period. The short-term success rate was 100% (26/26), and no complications were encountered during this study. Two (7.7%) patients underwent surgery during the observation period. The cumulative surgery-free rate after the initial EBD was 90.3% at both 2 and 3 years. The cumulative redilatation-free rate after the initial EBD was 52.1% at 2 years and 39.1% at 3 years.

CONCLUSION

EBD for strictures secondary to CD provides not only short-term success but also long-term efficacy. Although a high redilatation rate is one of the clinical problems of this procedure, EBD is an effective therapy for avoiding intestinal recession in CD -stricture.
