Anal Abscess/Fistula
| A patient who feels ill and complains of chills, fever and pain in the rectum or anus could be suffering from an anal abscess or fistula. |
An anal abscess is an infected space filled with pus found near the anus or rectum. An anal fistula typically occurs as a result of a previous abscess. This is a tunnel that connects the anal gland to the skin of the buttocks outside the anus.
Symptoms of an Abscess or Fistula
- Constant pain and swelling (not related to bowel movements)
- Irritation of the skin around the anus
- Drainage of pus (sometimes relieving the pain)
- Fever
Treatment of an Anal Abscess
Through an opening in the skin near the anus, the pus is drained from the infected area which relieves the pressure. This can be done at a doctor's office using a local anesthesia. A more severe abscess may require hospitalization and use of different form of anesthesia.
Treatment of an Anal Fistula
Treatment of an anal fistula requires surgery. This typically involves cutting a small portion of the anal sphincter muscle to open the tunnel and converting the tunnel into a groove which will heal from from within outward. Usually, this procedure is done on an outpatient basis, but may require a hospital stay.
