Comparative study between intersphinecteric ligation of perianal fistula versus conventional fistulotomy with or without seton in the treatment of perianal fistula: A prospective randomized controlled trial.

Background: Fistula-in-ano is one of the most common benign anal conditions in daily surgical practice.The goals in the treatment of an anal fistula are to eradicate sepsis and to eliminate the primary fistula opening, any associated tracts, and any secondary openings without a change in continence. Conventional fistulotomy (lay open of the fistula tract) is a commonly used procedure and is still relied on by the majority of surgeons as the gold standard for the treatment of perianal fistula.
