Procedure
Peri anal abscess drainage
Indications:
A Peri-anal abscess is an infection next to or in the area around the anus. Pus builds up under the skin causing pain and swelling. It may start to drain pus or blood-stained fluid. All perianal abscesses require surgical drainage.
Procedure:
During the procedure, the pus is let out through a cut in the skin next to the anus. The surgeon will try to determine if there is a fistula or tunnel connecting the inside of the anus with the abscess cavity. The wound is then washed out and usually left open without any stitches. The surgeon may decide to leave a plug made of gauze or sponge in the wound to be removed the following day.
Possible complications:
- There is a chance of damage to the circular anal muscle.
- During the operation, it may be necessary to excise necrotic or infected tissue, therefore, causing a large wound.
- Later complications may occur such as an anal stricture (narrowing of the anal opening).
- The chance of another abscess forming at a later stage is also recognized.
Duration:
Usually 30 minutes.
