Postoperative antibiotic use and the incidence of intra-abdominal abscess in the setting of suppurative appendicitis: a retrospective analysis.

Background: Although guidelines exist for postoperative antibiotic use in acute appendicitis that is perforated, gangrenous, or simple/uncomplicated, there are less data about its use in suppurative appendicitis. Here, we targeted this subgroup of patients to determine whether postoperative antibiotic administration affects incidence of intra-abdominal abscess formation.

Methods: We retrospectively examined 1,192 patients who underwent laparoscopic appendectomy for acute appendicitis at Kaiser Permanente Fontana Hospital between August 2010 and August 2013.
