Treatment of Anorectal Abscess with Underlying Immunosuppression, Cellulitis, or Systemic Signs of Infection

Not every anorectal abscess follows a straightforward course. When the presentation is complicated by cellulitis, systemic signs of infection, or underlying immunosuppression, the clinical situation calls for a more structured, evidence-based approach.

Clinical scenario

          Antibiotics are typically reserved for patients with an anorectal abscess complicated by cellulitis, systemic signs of infection, or underlying immunosuppression — including those with immunocompromised states. In these patients, antibiotic therapy may be used selectively alongside surgical management.
        

Treatment approach

The core intervention combines surgical drainage of the abscess with antibiotic therapy. The complete protocol — covering agent selection, timing, and clinical decision points — is available below.
