What Is an Anal Fistula?
An anal fistula is an abnormal tunnel connecting an infected anal gland or the anal canal to an opening in the surrounding skin. It commonly develops when an anal abscess drains but the connecting tract remains.

What Are the Types of Anal Fistula?
- Simple or low fistula: Limited sphincter involvement
- Complex or high fistula: Greater muscle involvement or branching
- Recurrent fistula: Returns after previous treatment
- Disease-related fistula: Associated with an underlying bowel or medical condition
Note: The fistula type helps determine whether the tract should be opened, removed, closed or managed using a seton.
What Are the Common Symptoms?
Symptoms may include:
- Irritation or itching near the anal opening
- A pimple-like swelling
- Discharge that may soil clothing
- A visible opening near the anal region
- Redness around the affected area
- Discomfort while sitting or passing stool
- Repeated swelling followed by discharge
What Causes an Anal Fistula?
An anal fistula typically forms after an infected anal gland turns into an abscess. Once the abscess drains, a small, abnormal tunnel can remain between the anal canal and the skin. Factors associated with complex fistulas may include:
- Crohn’s disease
- Tuberculosis
- Diverticulitis
- Previous trauma
- Sexually transmitted infections
- Pelvic radiation
- Selected pelvic conditions
How Is an Anal Fistula Diagnosed?
Diagnosis may include an outpatient physical exam and an anoscope exam. The internal opening, external opening, and fistula tract are identified before the condition is classified by location and extent.
MRI, ultrasound or contrast-assisted imaging may be considered for complex, branching or recurring fistulas. Mapping the tract and its relationship with the sphincter muscles supports procedure selection.
Which Fistula Procedures Are Available?
Dr Mainak Pal’s fistula treatment options include:
| Procedure | When It May Be Considered |
|---|---|
| Fistulotomy | Selected low fistulas involving limited sphincter muscle |
| Fistulectomy | Suitable cases where removal of the tract is planned |
| LIFT | Fistulas requiring closure between the sphincter muscles |
| Seton placement | Complex fistulas requiring drainage or staged treatment |

Note: Dr Pal advises patients when they can safely return to routine activities. Recovery varies with the procedure, fistula complexity and individual healing.
What Care Is Needed After Fistula Surgery?
Aftercare may include:
- Prescribed medicines

- Ongoing irritation and soiling
- Development of additional branches
- Scarring around the tract
- Increasing fistula complexity
- Greater disruption to daily activities
What Determines the Cost of Fistula Surgery?
The cost may depend on:
- Simple or complex fistula

- Anaesthesia requirements
- Hospital or day-care charges
- Medicines and surgical consumables
- Length of stay
- Follow-up requirements
- Insurance coverage
What People Also Ask
Can an anal fistula heal without surgery?
Most anal fistulas require surgery because the abnormal tract usually remains even when discharge temporarily stops.
Are anal fissures and fistulas the same?
No. A fissure is a tear in the anal lining, while a fistula is an abnormal tunnel connecting the anal canal to the skin.
How is the appropriate fistula procedure selected?
Selection depends on the fistula type, location, tract and internal and external openings. Sphincter involvement and previous treatment may also influence the plan.
Can a fistula return after surgery?
Yes. Recurrence is possible, particularly with complex or branching fistulas and underlying bowel conditions.
When does a fistula need urgent assessment?
Seek prompt care for increasing swelling, fever, severe discomfort, spreading redness or difficulty passing urine or stool.
