A perianal abscess is a collection of pus, outside the anus. Infection of an anal fissure, sexually transmitted infections, and blocked perianal glands are all thought to be inciting factors. The abscess usually begins when bacteria enters through a tear in the lining of the rectum or anus. Most often, this occurs between the internal and external sphincters (intersphincteric abscess), where the perianal glands are located. As the abscess increases in size, most will follow the plane of least resistance and spread towards the surface, creating a perianal abscess. A perianal abscess is caused by bacteria. Bacteria may enter the skin through a tear in the skin. The following steps may help: - Eat foods high in fibers to keep from becoming constipated.
