Treatments for an anal fistula

Unfortunately, there is no medication for treating or curing a fistula, but surgery seems to be very successful in treating this. Surgery is known to be the most effective way of treating fistulas. You may not need to go to the hospital for the surgery as this is a very normal surgery that can be done at a clinic too.

  • 1. This is a very simple surgery, if the fistula isn’t close to the anus, then at this point your doctor will cut the muscle or skin near the anus which helps in allowing it to heal from the inside and near the anus.
  • 2. Plug can also be used by your doctors for closing the fistula.
  • 3. In case of a rare or severe fistula, your doctor may put a tube (Setan) at the end or opening of the anus which helps in draining the pus or fluid which is infectious before starting the surgery.

Important:- it depends where your fistula is, accordingly your doctor will make a cut inside the sphincter muscles which helps in closing and opening the anus. The procedure is not dangerous but it will be a little harder to control your bowels after the surgery or treatment.


Complications may involve a fistula when it recurs after the treatment or when you are not able to control bowel movements. This mostly happens if muscles surrounding the anal opening which is known as the sphincter is removed.
