Perianal fistulodesis – A pilot study of a novel minimally invasive surgical and medical approach for closure of perianal fistulae

Figure 1 Effects of fistulodesis on perianal disease activity. A: Perianal disease activity index over time in all patients; B: Perianal disease activity index over time in seven patients with healing of at least one fistula upon fistulodesis. No statistical differences were observed when perianal disease activity index at screening and week 24 post-operative was compared (Wilcoxon test). PDAI: Perianal disease activity index; non-IBD: Non-inflammatory bowel disease; CD: Crohn’s disease.
