Treatment
Anal Fistula Treatment
Discomfort and frustration often accompany an anal fistula, but with the right diagnosis and treatment, most patients will be able to make a full recovery.
How an Anal Fistula is Diagnosed
No two fistulas are exactly alike. The size, position, and relationship to the anal muscles (sphincter) all affect the type of treatment needed. An accurate diagnosis is important to determine the most effective treatment plan.
Diagnosing an anal fistula usually involves the following:
Diagnosing an anal fistula usually involves the following:
- Physical Examination – A gentle inspection of the anal area is done to locate the external opening of the fistula and check for any swelling or discharge.
- Fistula Probing or Fistula Dye Test (Fistulography) – A fistula probe is inserted into the fistula to map the fistula tunnel. Sometimes, a contrast dye solution is used instead to identify the tunnel.
- Imaging (for complex cases) – Imaging tests like MRI scans or endoanal ultrasounds provide detailed images of the fistula’s path and its relationship to the anal sphincter muscles.
Treatment Options for Anal Fistula
An anal fistula rarely heals on its own. This is because the tunnel is still open and hence prone to getting infected by bacteria from the rectum and anal canal.
As such, surgery is usually needed to treat anal fistulas. The aim is to close the fistula tunnel and prevent it from recurring, while also preserving the anal sphincter muscles (which control bowel movement).

Fistulotomy
This is the most common procedure, especially for simple fistulas that do not pass through the anal sphincter muscles. It involves cutting open the fistula tunnel, removing the infected tissue, then flattening the tunnel and allowing it to heal from the inside out.
Seton Placement
This technique is for complex or high fistulas that cross the sphincter muscles. A surgical thread (seton) is placed through the tract to keep it open for continuous drainage; surgery might follow this.
Advancement Flap Procedure
The fistula is removed or cleaned out and a flap of healthy tissue is used to cover the fistula tunnel’s internal opening. This procedure is often used for recurrent or complex fistulas that pass through the sphincter muscles, when a fistulotomy is too risky.
LIFT Procedure
The LIFT (Ligation of Intersphincteric Fistula Tract) procedure is a sphincter-sparing technique where the internal opening of the fistula is tied off through a small incision between the sphincter muscles. The infected tissue is then removed and the incision is then closed.
Fibrin Glue or Plug
This involves using biological glue or inserting a bio-absorbable plug to close the fistula tract.
Possible Risks
and Complications
Possible Risks
and Complications
and Complications
While modern surgical techniques and an experienced surgeon can significantly reduce complications, some possible risks include:
- Recurrence of the anal fistula
- Infection
- Bleeding
- Bowel incontinence
Our doctor will manage these risks thoroughly and advise you on optimal recovery tips so that you heal better.
Recovery Tips Following Anal Fistula Surgery
- Expect mild pain, swelling, and occasional bleeding in the first few days
- Take prescribed pain medications as needed
- Keep the area clean to prevent infection and follow hygiene instructions carefully
- Resume light activities within a few days; avoid strenuous exercise and heavy lifting for several weeks
- Eat a high-fibre diet and stay hydrated to prevent constipation and reduce strain during bowel movements
- Attend follow-up appointments to monitor healing and prevent recurrence
