title: Effectiveness of Interval Appendectomy After Conservative Treatment of Pediatric Ruptured Appendicitis with Abscess.
abstract: The management of patients with acute perforated appendicitis with abscess is controversial. The aim of the present study was to assess the outcomes of treatment in patients with this condition. We retrospectively analyzed 31 patients (16 men and 15 women with a mean age of 8.4 years) with appendicitis presenting with abscess. Patients were divided into two groups (emergency operation group and interval operation group), and clinical characteristics and outcomes of treatment were investigated. On presentation, no differences in gender, age, body weight, duration of symptoms, temperature, white blood cell count, C-reactive protein level, or maximum size of the abscess in the axial view were detected between the two groups. Fifteen patients (48.4 %) underwent emergency surgery. The remaining 16 patients (51.6 %) were initially treated conservatively with antibiotics. All 16 patients underwent planned operations after receiving conservative treatment, and two (12.5 %) of these patients underwent appendectomy before the planned operation day because of recurrent appendicitis without abscess. There were no differences in the length of hospital stay. In the emergency operation group, six (40 %) patients presented with wound infection and four (26.7 %) developed a postoperative intra-abdominal abscess. No infective complications were reported in the interval operation group. Interval appendectomy after conservative treatment of pediatric ruptured appendicitis with abscess significantly reduced postoperative infection rates.
