Drainage of Anal Abscesses

An anorectal abscess can be defined as a collection of pus in the area of the rectum and anus. Causes of an anorectal abscess can include a blocked gland, an infection of an anal fissure, a sexually transmitted infection and possibly Crohn’s disease. One way to get rid of an anal abscess is to drain it.

How The Procedure Is Performed

Since anorectal abscesses rarely go away on their own, surgery is often needed to open and drain the abscess. Local anesthesia is first given to the patient and a small incision is made. The purulent contents of the abscess will be drained and sent away for a culture analysis. The area is then packed with iodophor gauze will be removed after 24 hours.


Twenty-four hours after the procedure the gauze used to packed the abscess will be removed by the doctor. Dr. Balasubramaniam will most likely suggest that three times a day as well as after each bowel movement you take a sitz bath to clean the area. Stool softeners and pain medication may be prescribed. The follow-up with the doctor usually takes place at around two or three weeks after the procedure.


One possible complication from the procedure to drain anal abscesses is the possible development of fistulous tracts. Fistulas are tunnels in the tissue that should not be there. As with any surgery, if you experience any adverse side effects contact your physician.

Additional Information

It has been discovered through cultures that underlying anal fistulas are present in roughly 40% of abscess cultures that are positive for intestinal bacteria.
