Fistula in Ano

A fistula in ano is an abnormal connection between the anal canal and the skin around the anus. It often results from an infection in the anal glands, which can cause abscesses that drain externally. Symptoms of a fistula include pain, swelling, discharge, and recurrent abscesses. Treatment typically involves surgical procedures, such as fistulotomy, to open the fistula and allow it to heal properly.
