What Is an Anal Fistula?

An anal fistula is an abnormal tunnel that develops between the inside of the anal canal and the skin around the anus.

Most anal fistulas occur after an anal abscess, where an infection forms a pocket of pus near the anus. Even after the abscess drains, a tunnel may remain, resulting in a fistula.

What Is Fistula Surgery?

Fistula surgery refers to procedures designed to remove or close the abnormal tract while preserving bowel control.

The ideal surgery depends on:

• Fistula location

• Complexity

• Involvement of sphincter muscles

• Previous surgeries

• Underlying diseases

Types of Anal Fistula Surgery

1. Fistulotomy

The most common procedure for simple fistulas.

How It Works

The surgeon opens the fistula tract completely, allowing it to heal from the inside outward.

Advantages

• High success rate

• Lower recurrence

• Relatively straightforward procedure

Best For

Simple fistulas with minimal sphincter involvement.

2. Seton Placement

A surgical thread or rubber band is inserted through the fistula.

Benefits

• Controls infection

• Allows drainage

• Protects sphincter muscles

Common Use

Complex fistulas.

3. Advancement Flap Procedure

Healthy tissue is used to cover the internal opening after cleaning the tract.

Suitable For

• Complex fistulas

• Patients at risk of incontinence

4. LIFT Procedure

Ligation of Intersphincteric Fistula Tract (LIFT) is a sphincter-preserving technique.

Advantages

• Less risk of incontinence

• Good healing outcomes

• Faster recovery in selected patients

5. Fibrin Glue and Bioprosthetic Plug

Minimally invasive methods used in selected cases.

Limitations

• Lower long-term success rates

• Possible recurrence

Risks of Fistula Surgery

Although fistula surgery is generally safe, complications can occur.

Possible Risks

• Bleeding

• Infection

• Delayed wound healing

• Recurrence

• Anal stenosis

• Fecal incontinence
