Surgical treatment is required during the acute phase of a perianal abscess. If surgery is not performed, it could lead to an expansion of the abscess cavity or worsening of the infection. Severe cases may lead to a local cellulitis around the anus, forming an inflammation of the cellular tissue. The surgical approach for a perianal abscess primarily involves incision and drainage, complemented by a one-time radical cure. The surgical principle mainly involves excising the infected local lesions altogether, thoroughly disinfecting and dressing the area, accelerating the shedding of the local infection, and ensuring normal growth of granulation tissue. Postoperative dressing changes are also crucial for the recovery from a perianal abscess.
