There is wide variation in the treatment of the anal fistula, but it should be not only curative but produce minimal disturbance of the anal function.
Apart from the usual fistula, there are fistulas occuring in patients with Crohn's disease and ulcerative colitis.
Five of seven patients with Crohn's disease and seven of seventy three with ulcerative colitis treated in the recent four years were accompanied with some anorectal fistula or abscess.
Less aggressive treatment is indicated for fistulas in these cases.
