In patients with active perianal Crohn's disease, the success of vedolizumab was defined by clinical success (no draining fistula at clinical examination and no anal ulcers for primary lesions) at 6\u00a0months without medical or surgical treatment for perianal Crohn's disease. Logistic regression analyses were performed to identify predictors of success. In patients with inactive perianal Crohn's disease, recurrence was defined by the occurrence of lesions and\/or the need for medical or surgical treatments.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>One hundred and fifty\u2010one patients were included. Among them 102 patients had active perianal disease, 33 (32.4%) males, mean age 39.8\u00a0years, mean Crohn's disease duration 14.6\u00a0years; 101 (99%) had received at least one anti\u2010TNF. The median follow\u2010up time was 52\u00a0weeks. Sixty\u2010eight per cent of patients discontinued therapy after a median time of 33\u00a0weeks. Vedolizumab success was reached in 23\/102 (22.5%). Among patients with setons at initiation, 9\/61(15%) had a successful removal. In multivariable analysis, factors associated with success were the number of prior biologic agents (\u22653, odds ratio, OR: 0.20, 95% CI 0.04\u20100.98) and no antibiotics at initiation (OR: 4.76, 95% CI 1.25\u201018.19). In 49 patients with inactive perianal Crohn's disease, perianal disease recurred in 15\/49 (30.6%), 11\/49 (22.4%) needed dedicated treatments.
