Recurrence of perianal fistulas after medical or surgical treatment is common (59%-82%). [52] In one study, one year after surgery for Crohn disease, 20%-37% of patients had symptoms suggestive of clinical recurrence, and endoscopic evidence of recurrent inflammation was in the neoterminal ileum in 48%-93% of patients.
