If a perianal abscess has already been treated surgically, it is necessary to develop good dietary and bowel habits postoperatively to reduce the likelihood of recurrence. However, recurrence may still occur due to poor diet and bowel habits of the patient. If there is pain or discomfort at the site of the local wound of the perianal abscess, it is advisable to go to the hospital as soon as possible for an anal examination and perianal ultrasound to confirm if it has recurred. If it is confirmed to have recurred, early surgical treatment is necessary to prevent further expansion of the local infection focus or aggravation of the infection, which would increase the difficulty of treatment later.
