If the perianal abscess is in the acute phase, one can opt for oral medication that clears heat, cools the blood, reduces swelling, and relieves pain, specifically designed for hemorrhoids, and it can be combined with oral antibiotics for anti-inflammatory treatment. However, treating a perianal abscess with oral medication alone can only alleviate symptoms or prevent the pus cavity from spreading too quickly, and does not provide a radical cure. The definitive treatment for a perianal abscess primarily involves surgery. The surgical method generally used is a one-time radical surgery for perianal abscesses, as the abscess forms a pus cavity and pus under the skin around the anus. Therefore, the surgery initially requires draining of the local pus, followed by thorough debridement of the walls of the pus cavity to allow fresh granulation tissue to regrow, filling the wound and facilitating the recovery of the local wound.
