A Fistulotomy is the surgical opening or removal of a fistulous
tract. They can be performed by excision of the tract and
surrounding tissue, simple division of the tract, or gradual
division and assisted drainage of the tract by means of a seton; a
cord passed through the tract in a loop which is slowly tightened
over a period of days or weeks.
Fistulas can occur in various
areas of the human body, and the location of the fistula influences
the necessity of the procedure. Some, such as ano-vaginal and
perianal fistulas are chronic conditions, and will never heal
without surgical intervention.
