In a retrospective review of a prospectively collected database for evaluation of the healing rate after operations for anal fistulas in New England colorectal surgery practices, the healing rates of fistulotomy, advancement flap, and fistula plugs at 3 months were 94%, 60%, and 20%, respectively. [50] The healing rate of the ligation of intersphincteric fistula tract procedure at 3 months was 79%. Hospitals that performed more ligation of intersphincteric fistula tract procedures had higher healing rates at 3 months. [50]
