If a perianal abscess is treated with a one-time radical surgery, the recurrence rate is very low. However, it is still necessary for the patient to develop good dietary and bowel habits post-surgery. Since the main cause of perianal abscesses is repeated infection in the anal crypts locally, it is essential to maintain a light diet and regular bowel movements to prevent symptoms of diarrhea.

If chronic diarrhea occurs, it may lead to the retention of infectious materials in the anal crypts, causing repeated infections there. Moreover, if the patient does not maintain a light diet, it might further aggravate the infection, leading to recurrence. If postoperative patients pay attention to a light diet and regular bowel movements, the possibility of recurrence is very low.
