Insights
Interval appendectomy for pediatric perforated appendicitis with abscess significantly lowers infection rates. This approach, following initial antibiotic treatment, proves safer than immediate surgery, reducing complications like wound infections and intra-abdominal abscesses.
Area of Science:
- Pediatric Surgery
- Gastrointestinal Surgery
- Infectious Disease Management
Background:
- Management of acute perforated appendicitis with abscess in children remains a clinical challenge.
- Treatment strategies vary, with ongoing debate regarding the optimal timing of surgical intervention.
Purpose of the Study:
- To evaluate and compare treatment outcomes for pediatric patients with perforated appendicitis and abscess.
- To assess the efficacy of emergency surgery versus interval surgery after conservative management.
Main Methods:
- Retrospective analysis of 31 pediatric patients diagnosed with appendicitis and abscess.
- Patients were categorized into two groups: immediate (emergency) operation and delayed (interval) operation after antibiotic therapy.
- Clinical data and treatment outcomes, including infectious complications and hospital stay, were compared between groups.
Main Results:
- No significant differences were observed in baseline characteristics between the emergency and interval operation groups.
- The emergency operation group experienced higher rates of postoperative complications, including wound infection (40%) and intra-abdominal abscess (26.7%).
- The interval operation group, following conservative antibiotic treatment, reported no infective complications.
Conclusions:
- Interval appendectomy after initial conservative management for pediatric perforated appendicitis with abscess is associated with significantly reduced postoperative infection rates.
- This strategy appears to be a safer approach, minimizing surgical site infections and intra-abdominal abscesses in this patient population.
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.
