The first thing you should do is to prevent perianal infections, pay attention to local hygiene, insist on daily cleaning baths, and pay attention to adjusting the diet structure, reasonable meals, and develop the habit of defecating on time. If recurrent perianal infections do not improve, surgery should be performed in a timely manner, especially for acute perianal abscesses or chronic fistulas. The purpose of surgical treatment is to prevent infection and aggravation of the fistula, and to promote healing of the wound. During the treatment period, patients should be advised to increase their dietary nutrition, mainly high protein foods, and to pay attention to proper local functional exercises to prevent the proliferation of scar tissue, timely cleaning after each bowel movement to prevent infection of the trauma, and to insist on changing medication. If there is an obvious abscess, pus should be retained for bacterial culture and smear, and targeted anti-infection treatment should be given. In addition to a reasonable dietary structure, attention should be paid to increasing nutrition to promote wound healing.
