Incision and Drainage (I&D) of Perianal Abscess

The incision and drainage (I&D) of an abscess is done to drain the pus and reduce swelling and pain.

Anal Abscess
An anal abscess is an infection of the tissue around the anus. The pus that is produced cannot be excreted and collects in a wide area. The severity and depth of each abscess varies. An anal abscess can develop into a fistula, which is an abnormal opening between the anus and the surrounding skin.
This procedure is done in the operating room. The abscess is drained and the collected fluid is sent to the laboratory for testing. The doctor may place gauze in the wound or a drain to remove fluid.
The success of the procedure depends on many factors. Please talk to your doctor about this.
What if the procedure is not performed?
If an infected abscess is not drained correctly, the infection may spread to surrounding tissue or to the blood. The abscess may also rupture and do the same, causing painful complications.
Anal abscesses usually require drainage. Antibiotics alone may not treat the problem effectively, except in certain cases where it may be clear that antibiotics are a better option than surgery.
