Intra-abdominal abscess a well-known complication of both open and laparoscopic appendectomy, especially in the setting of perforated and gangrenous appendicitis. The reviewed literature cites an incidence of about 10%. Besides peri-operative antibiotic administration there have been few developments to reduce this inherent risk. Oxygen rich environments are potently bactericidal, and thus it is our hypothesis that establishing an oxygen rich ambience within the abdomen at the conclusion of laparoscopy could curtail bacterial growth and subsequent abscess formation.
