Perianal abscess

The year It is the terminal orifice of the digestive tube through which the stool exits in the process of defecation. It is located in the lower pole of the perineum and is the end part of anal canal, a conduit about two centimeters long.

The anus consists of two sphincters that control stool retention or output, the internal anal sphincter, which is involuntary, and the external, muscular, which is voluntary. It is covered by a skin that is thinner than usual, lacking both glands and hairs. Inside the anal canal there are glands that flow into structures called anal crypts.

If these glands are obstructed and they become infected, accumulating pus in them, what is known as a perianal abscess occurs.

Causes of perianal abscess?

Perianal abscesses are more frequent in men than in women (2: 1) and in 90% of cases they are caused by an obstruction of the anal crypts. By clogging the glands and not being able to drain their contents, they can become superinfected and the accumulation of pus leads to the formation of the abscess. General Medicine Specialist
