Comparison of endoscopic balloon dilation and surgery for duodenal stricture in patients with Crohn's disease.

Few studies have compared endoscopic balloon dilation (EBD) and surgery in the treatment of duodenal stricture in patients with Crohn's disease (CD). We performed a retrospective study to compare the efficacy and safety among patients with CD-associated duodenal stricture treated with EBD or surgery from October 2013 to December 2021. Univariate and multivariate analyses were performed to evaluate factors associated with recurrence-free or surgery-free survival. A total of 48 eligible patients were included, including 30 patients treated with EBD only and 18 patients treated with surgery. Patients treated with surgery experienced more symptomatic improvement (100% vs. 63.33%, p = 0.003) and significantly longer recurrence-free survival (6.31 [IQR: 3.00–8.39] years vs. 2.96 [IQR: 1.06–5.42] years, p = 0.01) but suffered more postprocedural adverse events (16.67% vs. 0.74% per procedure, p = 0.001). In patients initially treated with EBD (n = 41), a total of 11 (26.83%) required subsequent surgical intervention. Younger age at CD diagnosis (HR = 0.90, 95% CI: 0.81–1.00, p = 0.04) was associated with a higher risk for subsequent surgery. Surgery for CD-associated duodenal strictures was associated with a longer recurrence-free survival. EBD was safe and effective with minimal postprocedural adverse events but led to a high frequency of recurrence. [ABSTRACT FROM AUTHOR]
