Proctology assessment and treatment planning

Identifying an anal fistula and protecting sphincter function

An anal fistula is an inflamed tunnel between the anal canal and nearby skin. Recurrent swelling, pain or an opening that drains pus should be assessed. Treatment depends on the route of the fistula and its relationship to the sphincter muscles.

How an anal fistula may develop

Many fistulas follow an infection of glands in the anal canal and an anal abscess. After the abscess drains or is opened, a tunnel between the bowel and skin may remain.

Common signs include recurrent discharge, pus or blood, skin irritation and pressure pain. Fever, increasing swelling and severe pain can indicate an acute abscess and need prompt care.

Assessment and classification

Assessment may include inspection, a careful rectal examination and proctoscopy or rectoscopy. Ultrasound or MRI can provide more detail for complex or recurrent fistulas.

The fistula's relationship to the sphincter muscles helps determine which treatment best balances healing with preservation of bowel control.

Treatment adapted to the fistula

Anal fistulas do not usually heal permanently without a procedure. A superficial tract is treated differently from one that crosses more of the sphincter. When an abscess is present, safe drainage of the infection comes first.

The surgeon explains the available procedures, healing prospects, recurrence risk and possible effects on continence before a decision.

Good to know

Frequently asked questions

Is an anal fistula the same as an anal abscess?

No. An abscess is an acute collection of pus. A fistula is a tunnel that can remain after an infection or abscess.

Does an anal fistula require surgery?

Permanent healing usually requires a procedure. The fistula tract, sphincter involvement and previous treatment determine the suitable method.

When do I need urgent medical help?

Severe increasing pain, fever, chills or rapidly increasing swelling can indicate an abscess and should be assessed promptly.
