The general procedure of perianal abscess surgery includes anesthesia, disinfection, toweling, incision, drainage, flushing, stuffing and bandaging.
1. Anesthesia: Generally, perianal abscess surgery needs to be performed under local anesthesia or half anesthesia.
2. Disinfection: after successful anesthesia, the operator needs to disinfect the perianal skin, routinely disinfect three times.
3. Toweling: A sterile cavity towel will be spread on the buttocks, exposing the abscess area and the perianal area.
