Causes & Symptoms


Most fistula’s are a sequel of an previous abscess or pus cavity. The pus formation is the result of an anal gland infection. When this abscess fails to heal completely, with or without treatment , a fistula develops. This tract will get some stool pieces entering the tract from time to time leading to infection and pus/ mucous discharge again and again thus makes it a non-healing wound. No fistula can be treated without surgery.
