Anal fistula is the most common form of perianal sepsis. The etiology includes idiopathic fistulas, caused by cryptoglandular infection and fistulas secondary to other causes (Crohn's disease, iatrogenic, specific infections). Typically, a fistula includes an internal opening, a track, and an external opening. The treatment of anal fistula is a real challenge because of a risk of recurrence and anal incontinence. Fistulotomy is the gold standard: it is effective in terms of eradication of the fistula tract but it carries a risk of incontinence. Because of this risk, particularly for complex fistulas, sphincter-preserving techniques have been evaluated. Otherwise, success rate are lower than fistulotomy. Recents tecniques have interessant results (ligation of the intersphincteric fistula track, laser) but the lack of consistent results, level evidence and long-term follow-up, as well as the heterogeneity of fistula pathology avoid a definitive treatment algorithm.
