About Perianal Abscess
A perianal abscess is an infected cavity filled with pus found near the anus or rectum.
What causes an abscess?
An abscess results from an acute infection of a small gland just inside the anus, when bacteria enter the tissue through the gland. Certain conditions - colitis or other inflammation of the intestine, for example - can sometimes make these infections more likely.
What are the symptoms of an abscess?
Typically acute pain and swelling which are only relieved by drainage of pus. This may occur spontaneously or after intervention by your surgeon.
How is an abscess treated?
An abscess is treated by draining the pus from the infected cavity, making an opening in the skin near the anus to relieve the pressure. This is usually done in hospital under a general anaesthetic. Once it has been drained the abscess cavity will quickly diminish is size and either heal completely or persist as a fistula. Simple dry dressings and antibiotics are usually all that are required during this period.
