An Overview of Anal or Rectal Abscess
Anorectal abscess - Wikipedia
It arises as a complication of paraproctitis. Ischiorectal, inter- and intrasphincteric abscesses have been described. Pain in the perianal area is the most common symptom of an anorectal abscess. The pain may be dull, aching, or throbbing. It is worst when the person sits down and right before a bowel movement. After the individual has a bowel movement, the pain usually lessens.
An anorectal abscess also referred to as an anal abscess, rectal abscess, perianal abscess, or perirectal abscess depending on its location is a pus-filled cavity that forms within the furrows of the anal canal called the anal sinuses. Abscesses can form near or within the anus or develop much higher up in the rectum itself. While an abscess can form spontaneously for no apparent reason, it is commonly associated with gastrointestinal disease, bowel irregularities, immune suppression, and even certain medications. Anorectal abscesses are usually first recognized because of dull, throbbing pain in the anus or rectum, often accompanied by sharp pain when defecating. Perianal abscesses "peri-" meaning around are the most common type and can usually be identified visually as they occur in the upper layers of tissue.
The anus is that part of the intestinal tract that passes through the muscular canal of the pelvis and anal sphincters. It is the final orifice through which stool passes out of the body. In adults, the anus is 4 to 5 centimeters long. The lower half of the anal canal has sensitive nerve endings. There are blood vessels under the lining, and in its mid portion there are numerous tiny, anal glands.
