A fistulotomy is a surgical operation used to treat a fistula in the anal area. An anal fistula is a tiny aperture or tunnel that forms between the anal skin and the end of the anus. Anal fistulas can be caused by injury, severe inflammation, infection, or pus collection in the region. Symptoms of this illness include:

  • Pain and discomfort worsens when you cough, move around, sit down, or relieve yourself.
  • Difficulty controlling bowel movements.
  • Skin inflammation near the anus.
  • Discharge with blood or pus
  • Smelly discharge around the anus
  • Swelling and redness at the anus
  • Fever

An anal fistulotomy procedure involves opening and draining the fistula to aid in healing. Surgery is usually the best option.


Outpatient surgery is often performed at the doctor’s office. When the fistula is large, you may require hospitalization, and the procedure will be performed in the operating room under general anesthesia.

During the procedure, the doctor will make a cut at the site of the fistula. They will remove the entire affected area, including pus and other fluids. They will then suture the area and allow it to recover. In some circumstances, they’ll leave it open while packing or covering the region with gauze.


The primary purpose of a fistulotomy is to drain all pus and fluids from the afflicted region or tissues. This promotes faster healing and helps to close the irregular gap. The operation also helps to protect the anal sphincter.
