BACKGROUND AND AIMS: Intestinal strictures are a common and serious adverse event of inflammatory bowel disease (IBD). Endoscopic balloon dilation (EBD) is the first step in treatment to avoid surgery. The aim of this study was to assess the prevalence, risk factors, and clinical sequelae of difficult EBD.
METHODS: This retrospective, multicenter study included 861 patients with IBD treated with EBD due to strictures. Risk factors for difficult EBD, defined as ≥3 per year, were evaluated.
RESULTS: During a median (IQR) of 23.00 (14.00-42.00) months of follow-up, there were 392 (45.5%) easier EBDs performed, while difficult EBDs were performed in 489 (54.5%) cases. Long-term efficacy of EBD, defined as >12 months without surgery, was achieved in 392 (100%) easier EBDs versus 457 (97.4%) difficult EBDs (Cramer's V = .11; P = .004). However, 149 (17.3%) patients underwent surgery for unsuccessful EBD. The most important risk factors for difficult EBD, classified as modifiable, were smoking and treatment with adalimumab (especially if trough levels were normal) and ustekinumab. Vedolizumab and immunosuppressive therapy were identified as protective factors. Multivariable logistic regression analysis indicated good fit of the model to the data, pointing to a protective role for total parental nutrition and worsening of smoking (both, P < .001).
CONCLUSIONS: Reduction of difficult EBDs should be considered primarily in the context of their modifiable risk factors. Prospective studies with simultaneous evaluation of transmural healing are needed to truly assess whether vedolizumab treatment, immunosuppressive therapy, and total parenteral nutrition reduce the risk of EBD.
