Brief Answer:
Surgery is the best option

Detailed Answer:
Hi,
Thank you for posting your query in Healthcaremagic.com.
This is Dr. Swarnava Dattagupta answering your query.

I understand your concern.
But I am afraid that till date, surgery is the best option to treat an established case of anal fistula.
There are different types of treatment for various types of fistula, depending on location, depth of involvement and presence of abscess etc.
However, surgical treatments in form of seton techniques, fistulotomy and modern surgical methods like video assisted fistula treatment etc are very effective. The post operative relief from symptoms is quite effective as well as recurrence rate is also low.
Some non-surgical options like injection of fibrin glue in the fistula tract has been tried widely but though immediate effect is good, the recurrence rate is high. Hence, its use is bit controversial.
So my suggestion will be to visit a General surgeon and get clinically examined. Accordingly, your treatment options can be decided. Surgical management should be the priority.

Hope I have answered your question.
If you have any further questions I will be happy to help.
Regards.
