Perianal abscesses that have not ruptured generally involve two scenarios. First, the application of topical or oral antibiotics may eliminate the local abscess, but some infection foci and swelling may persist, with a possibility of recurrence later. The second scenario occurs when the abscess does not rupture, but the pus chamber further expands, leading to an increase in the area of infection and thus worsening systemic infection symptoms. Once a perianal abscess is detected, it is necessary to treat it promptly. If an early-stage typical pus chamber has not formed, antibiotics can be used for symptomatic treatment to reduce local inflammation. If a clear pus chamber has formed and is accompanied by pus, it is advisable to promptly perform an incision and drainage of the abscess, followed by a definitive surgical debridement.
