Perianal abscess is an acute infectious disease localized around the anus. If a perianal abscess acutely erupts, it requires prompt surgical treatment. Without surgery, there is a possibility of recurrent episodes of perianal abscesses or the formation of anal fistulas due to the rupture of the abscess. After surgery for a perianal abscess, it is also important to pay attention to a light diet and regular bowel movements. It is crucial not to allow the stool to become too dry, nor to experience diarrhea. Recurrent diarrhea can lead to infection of the anal crypts, thereby causing perianal abscesses and local infections. Therefore, the care of a perianal abscess is very important; maintaining good dietary and bowel habits is essential to prevent recurrence of the abscess.
