Anal fistulas are the result of an infection that starts in an anal gland. The infection results in an abscess which is a collection of pus inside. When there is a single opening inside the anal canal, it is called the sinus. When it opens outside and pus starts coming out, it is called Fistula.

In simpler terms, Fistula is a tract that opens from the rectum creating a hole in the walls of the bottoms. The tract exposes the faecal matter to escape through it. As these tracts do not have sphincters to control the flow, pus & other faecal matter flows without control of the patient. This creates a difficult & awkward situation for the patient in daily life. If not treated at an early stage, the infection may spread and multiple tracts can form, which makes it a complex fistula. Get treated for your fistulas by experts only for effective treatment.
