Once a perianal abscess is discovered in clinical practice, it's recommended to undergo surgical treatment as soon as possible, rather than using anti-inflammatory drugs for anti-infection treatment.

This is because perianal abscesses are primarily caused by inflammation of the anal glands, leading to swelling and redness around the anus. Treating with only anti-inflammatory medications can temporarily control the condition, but the already infected tissues and the internal opening are not adequately treated. Improper diet or staying up late can lead to recurrence, or even lead to anal fistulas or necrotizing fasciitis.

Therefore, for perianal abscesses, it is recommended to promptly undertake procedures such as incision and drainage of the perianal abscess, or a one-time radical surgery for perianal abscesses. However, for a minority of patients with perianal abscesses, such as subcutaneous perianal abscesses, if the area is relatively small, applying ichthammol ointment topically combined with oral administration of anti-inflammatory drugs or antibiotics can generally improve the condition within five to six days.
