During the acute phase of a perianal abscess, there is generally severe pain in the anal area, accompanied by redness and throbbing of the skin, and there may be a pus cavity or pus encapsulation under the skin. The treatment of perianal abscess is mainly surgical. The surgical method is incision and drainage, combined with a one-time radical surgery. If the infection involves the local sphincter or has already formed a clear fistula, further incision and ligation surgery may be required. After surgery, it is necessary to thoroughly disinfect and change the dressings of the wound to prevent excessive granulation or the formation of false healing at the local wound. Postoperative diet should consist mainly of light, liquid foods, and spicy and irritating foods should be avoided.
