An anal fistula is an abnormal tunnel that forms between the anal canal â the last portion of the digestive tract â and the skin around the anus. It almost always develops after an anal abscess (a pocket of infected pus in one of the small glands lining the anal canal) that doesn’t heal completely, leaving behind a persistent channel.
Common symptoms include:
If you notice these symptoms, see a colorectal specialist promptly an untreated fistula tends to worsen rather than resolve on its own.

The most common type. It tracks between the internal and external anal sphincter muscles and usually results from an infected anal gland.
Passes through both the internal and external sphincter muscles, typically caused by a deeper abscess infection.
Extends above the internal sphincter muscle, often from a spreading abscess infection. More complex to treat.
Travels beyond the external sphincter entirely, usually linked to chronic or recurrent infection. The rarest and most complex type.
Diagnosis begins with a physical examination and a review of your medical history. Your doctor will visually inspect the anal area for inflammation, swelling, or discharge, and may perform a digital rectal exam to check for abscesses.
To map the fistula tract precisely before surgery, your surgeon may order:
Early, accurate diagnosis prevents complications and improves surgical outcomes.
Anal fistula treatment is broadly surgical or non-surgical. Because a fistula rarely closes on its own, surgery is considered the definitive treatment in almost all cases.
Laser Fistula Surgery (FiLaC): A thin laser probe is guided into the fistula tract under anesthesia. Laser energy seals the tract from within by causing controlled thermal injury, without cutting the sphincter muscle. This is the treatment HeptaCare Health recommends for most patients due to its minimally invasive nature, low complication rate, and fast recovery.
Fistulotomy: The fistula tract is surgically opened and cleaned out so it can heal from the inside. Effective for simple, low fistulas, but not ideal when a large amount of sphincter muscle is involved.
LIFT Procedure (Ligation of Intersphincteric Fistula Tract): The fistula tract is accessed between the sphincter muscles and tied off, sealing the internal opening while preserving sphincter function.
Seton Placement: A surgical thread is looped through the tract to keep it draining and allow gradual, staged healing â often used for complex fistulas or as a first step before definitive surgery.
Advancement Flap Procedure: Healthy tissue from nearby is used to cover the internal opening of the fistula, promoting closure while preserving the sphincter â typically used for more complex or recurrent fistulas.
Fibrin Glue Injection: A biological glue is injected into the tract to seal it without any incision. It is the least invasive option, but success rates are lower than surgery, and it is generally reserved for select cases rather than used as a first-line treatment.
Benefit | Why it matters |
|---|---|
Minimally invasive | Small incisions, high-precision laser reduces bleeding and infection risk |
Shorter recovery | Most patients heal in 2â6 weeks; many resume desk work in 3â7 days |
Sphincter-preserving | Precise laser cuts spare surrounding muscle, lowering incontinence risk |
Day-care procedure | Completed in 30â40 minutes; most patients go home the same day |
Lower recurrence | Reported recurrence around 5â10%, lower than conventional surgery |
Cost depends on the complexity of the fistula, the surgical technique used, hospital and surgeon fees, anesthesia, and diagnostic tests (MRI/fistulogram). Below is an indicative range â always confirm your exact quote after an in-person or video consultation.

Most health insurance plans cover anal fistula surgery when medically necessary. HeptaCare Health’s insurance desk assists with cashless claims, and eligible patients can also opt for No-Cost EMI to spread the cost interest-free.
A successful surgery means the wound heals completely with no residual tract, external opening, or discharge. Recurrence, when it happens, usually traces back to one of these causes:
Poor wound hygiene: Not keeping the surgical site clean increases infection risk and can prevent full healing.
Not following post-operative instructions: Skipping medication schedules, wound care, or follow-up visits delays healing and raises recurrence risk.
Unaddressed underlying risk factors: Conditions such as Crohn’s disease, chronic constipation, or repeated infections can cause a new fistula to form if not managed alongside surgery.
Contact your surgeon promptly if symptoms persist or worsen.
As with any procedure, laser fistula surgery carries some risk, though rates are lower than with conventional surgery:
Left untreated, an anal fistula can progress to chronic abscesses, sepsis, peritonitis, fecal incontinence, non-healing wounds, and â in rare, long-standing cases â an elevated risk of anal cancer. Early treatment avoids these outcomes.

aser surgery is generally far less painful than conventional surgery. Because the laser targets the fistula tract precisely with minimal damage to surrounding tissue, most patients report less post-operative pain, reduced bleeding, and a quicker return to normal activity. Any discomfort is usually well controlled with prescribed medication.

It's uncommon. A true fistula tract rarely closes on its own because it's lined with tissue that resists natural healing. Non-surgical fibrin glue injection works for a minority of simple cases; surgery remains the definitive, most reliable treatment.
Modern sphincter-preserving techniques â laser surgery, LIFT, and advancement flap are specifically designed to minimize this risk. Incontinence is an uncommon complication and is discussed in detail with your surgeon based on the fistula's location before any procedure.
