Anal Fistula Surgery

When is Anal Fistula Surgery Recommended?

Often, anal fistulas do not heal on their own. Treatment is generally necessary to reduce chances of infection in an anal fistula and to alleviate symptoms. Many fistulas do not respond to non-surgical therapies such as and thus require surgery and/or wound care.

Surgery is usually recommended when:

Symptoms persist despite medication or drainage
There is ongoing pain, swelling, or discharge
Recurrent anal abscesses occur
The fistula affects daily comfort or hygiene

Surgical treatment addresses the underlying tract rather than just managing symptoms.

What To Expect?

Before the procedure

Limit or cut out smoking or alcohol.
Stop all current medications one week prior to the procedure or as instructed by your doctor.
You may be given bowel preparation to help you clear your bowels before the surgery.
You will be asked to fast accordingly.

During the procedure

You will be given anaesthesia to aid in falling asleep.
Your surgeon will guide a probe into your fistula.
The probe is used as a guide to cut along the length of the fistula.
A tool is used to scrape out any tissue buildup from your fistula and any abscesses may also be drained.
Your surgeon may need to close the rectal opening to the fistula. The other opening on the skin will be held open with stitches or other alternatives. This is to allow fluid to drain and the wound to heal.
A bandage may be placed over your wound. Healing may take any time from one to four months on a case-by- case basis.

After the procedure

You may be discharged on the same day or within the next few days.
Discomfort will be mild to moderate for the first week post-operation. Painkillers may be administered to place this under control.
Laxatives may be prescribed to soften your stools to ease bowel movement.
Eat a diet high in fibre and consume plenty of fluids. This will also help to soften your stools.
Wear dressing to cushion the affected area to prevent the drainage from soiling your clothes.
You will need to change dressing daily.
You will likely be able to resume normal activities within one to two weeks.
Schedule a follow-up appointment with your doctor within the next two weeks.

Frequently Asked Questions

What are the risks of anal fistula surgery?

While complications are relatively uncommon, they can include bleeding, infection, recurrence of the fistula, damage to nearby structures, or changes in bowel or sexual function. Your doctor will discuss the potential risks and benefits with you before the surgery and take necessary precautions to minimise complications.

How long is the hospital stay after a fistulectomy?

The duration of hospital stay after a fistulectomy can vary depending on individual factors and the complexity of the procedure. In many cases, patients can be discharged on the same day of the surgery or within 24 hours. However, in more complex cases or if additional monitoring is required, a short hospital stay of a few days may be necessary.

Your doctor will provide specific information regarding the expected duration of your hospital stay based on your unique circumstances.

Will my bowel movement be normal after the procedure?

Following a fistulectomy, bowel movements typically return to normal. However, it is normal to experience some temporary changes in bowel habits during the healing process, such as minor discomfort or changes in stool consistency. These changes usually resolve within a few weeks.

It’s important to maintain a healthy diet, stay adequately hydrated, and follow any post-operative instructions provided by your doctor to support a smooth recovery and promote optimal bowel function. If you have concerns about your bowel movements after the procedure, discuss them with your doctor for appropriate guidance and reassurance.
