Anal Fistula

Anal Fistula is rather an abnormal linkage between the perianal skin and the epithelialised surface of the anal canal, originating from the anal glands and draining into the anal canal. If the outlet of the anal glands gets blocked, it can form an abscess that gradually points onto the skin surface and results into the formation of the tract called fistula. Abscesses may erupt again if the fistula is sealed, enabling the buildup of pus. Then it again points to the surface and the process repeats. Anal fistula generally do not cause any harm, but eventually becomes very painful and frustrating due to the pus-drain. Its primary symptoms include pain, blood discharge, itching and systemic symptoms in case of infected abscess.
