The primary cause of perianal abscesses is the repeated inflammatory stimulation near the dentate line of the anus, leading to infection. As the infection worsens, localized foci of infection form, resulting in the formation of pus and abscesses. Once a perianal abscess has formed, the patient will experience severe pain and will require prompt surgical treatment. If a definitive one-time surgery for the perianal abscess is chosen, it can be completely treated. Post-surgery, simply changing the dressing on the local wound will suffice, and the wound is expected to fully heal and recover. However, if an incision and drainage surgery was performed for the perianal abscess, a fistula may have already formed, requiring a second surgery for cutting and threading the fistula.
