Is discharge after fistula surgery a sign of recurrence?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I was operated on for an anal fistula four months ago. I was made to take a Sitz bath and antibiotics. The wound is all right, and there was no problem till 15 days back when I started feeling a watery discharge from the anus, especially when I walk for a distance.

There is no foul smell. Sometimes I also feel a slight pain in the anus in the area of the operation. Please suggest if it is fine or if there is a problem. Please help.

Thank you.

Hello,

Welcome to icliniq.com.

You must know and remember that an anal fistula is a condition that has a fairly high recurrence rate, meaning it has a tendency to occur again after the operation. A complete cure is very difficult. I strongly suspect that you have got a fistula-in-ano again. Sometimes, a previous surgery or treatment does not heal completely, which can cause the problem to continue. In other cases, an underlying condition such as an ongoing infection or inflammation may be preventing proper healing.

To understand exactly what is going on, doctors need a clear picture of the affected area. An MRI fistulogram helps map the fistula’s path and shows how severe it is. Along with this, additional tests may be done to check for hidden or secondary causes, especially if healing has been delayed.

Because some conditions cause similar symptoms, doctors also consider other possibilities. These include a recurrent fistula, which means the fistula has returned, or a perianal abscess, which is a painful collection of pus near the anus.

Treatment is planned step by step to ensure the best outcome. First, the fistula is carefully identified through imaging. Next, doctors rule out any underlying causes. If a secondary problem is found, it is treated first. Finally, if the fistula still does not heal, surgery may be recommended.

While treatment is ongoing, simple daily care can make a big difference. Keeping the area clean and dry reduces infection risk, and regular sitz baths (sitting in warm water) can ease pain and promote healing.

Please consult your treating surgeon for the same. There can also be some conditions in which there is a high rate of recurrence of fistula if not treated primarily, such as tuberculosis, Crohn's disease, malignancy, etc.

I hope this helps.

Kindly revert in case of further queries.

Thank you.
