The medicine will not be changed on the day of perianal abscess surgery. The morning after the surgery, patients are advised to remove the gauze from the anal wrap, defecate, exhaust, and give a fumigating sitz bath with herbs that clear heat and dampness, reduce swelling and pain after the stool. Patients are advised to control their diet and stools 1-2 times a day. Drug changes are usually 1-2 times a day, too many drug changes can cause damage to the new granulation tissue of the trauma and delay healing. Less frequent or no drug changes may also lead to pseudo-healing of the wound and risk of reoperation. The wound is gently dabbed with a clean cotton ball, disinfected with Neosporin or iodophor, given an appropriate amount of ointment or suppository after cleaning, and drainage gauze is placed on the wound to keep the drainage open. If the wound is deeper or larger, it can be rinsed with antiseptic water, such as saline or metronidazole, cleaned and then given ointment or suppositories and placed on drainage gauze. The outer dressing can be changed several times if the perianal abscess and fistula have more exudate, but the number of wound dressing changes should not be too many to avoid destroying too much new granulation tissue and delaying wound healing. The duration of perianal abscess is longer than that of hemorrhoids, generally about 30-40 days, and minor abscesses may also heal in 20 days. After healing, you should also frequently clean the anus and reduce the consumption of spicy and irritating or cow and sheep hair products to prevent local recurrence.
