Sometimes a fistula gets infected and the infection results in an abscess that drains spontaneously. The fistula then forms a tunnel under the skin and connects with the infected gland. Surgery is usually needed to treat anal fistula. Vithai PilesTreatment Centre offers the best facility for laser treatments, our centre is clean and welcoming. The laser treatment is non-invasive and the patient can often go back home and resume their routing within the same day.
