Treatment: Intraperitoneal Abscesses

• Antimicrobial therapy is adjunctive to drainage and/or surgical correction of an underlying lesion or process.
  • - Diverticular abscesses usually wall off locally, and surgical intervention is not routinely needed.
  • - Antimicrobial agents with activity against gram-negative bacilli and anaerobic organisms are indicated (see “Secondary Peritonitis,” above).
