Drainage of perianal abscess is usually a straightforward procedure to treat a perianal abscess. The procedure is usually performed under a general anaesthetic, as the perianal region can be acutely sensitive, and also to allow the surgeon to assess the extent of the infective process. In most situations, a single incision is needed to drain the abscess. Once the pus is drained, the abscess cavity is usually washed out and dressed with a simple wound dressing.
After the procedure, the surgical wound will need ongoing wound care. Your doctor will give you further instructions about this wound care before you leave hospital.
