The surgeon will allow the abscess to drain its exudate and attempt to discover any other related lesions in the area. This is one of the most basic types of surgery, and is usually performed in less than thirty minutes by the anal surgical team. Generally, a portion of the exudate is sent for microbiological analysis to determine the type of infecting bacteria. The incision is not closed (stitched), as the damaged tissues must heal from the inside toward the skin over a period of time. The affected individual is often sent home within twenty-four hours of the surgery, and may be instructed to perform several sitz baths per day. These involve a small basin which is filled with warm water, and possibly with salts; usually fits over a toilet;  and soaks the affected area for a period of time. Another method of recovery involves the use of surgical packing. The initial packing is inserted by the surgical team, with redressing generally performed by hospital staff or a district nurse. During the week following the surgery, many patients will have some form of antibiotic therapy, along with some form of pain management therapy, consistent with the nature of the abscess.
