High-resolution ultrasonography (US) accurately diagnoses acute appendicitis in children. This imaging technique shows high sensitivity and specificity, aiding in early detection and preventing complications.

Area of Science:

  • Pediatric Radiology
  • Abdominal Imaging
  • Emergency Medicine

Background:

  • Acute appendicitis is a common surgical emergency in children.
  • Accurate and timely diagnosis is crucial to prevent complications like perforation.
  • Clinical presentation can be ambiguous, necessitating reliable diagnostic tools.

Purpose of the Study:

  • To prospectively evaluate the diagnostic accuracy of high-resolution ultrasonography (US) for acute appendicitis in children.
  • To compare the diagnostic performance of US in pediatric patients with previously reported adult series.
  • To assess the utility of US in identifying alternative diagnoses in children with suspected appendicitis.

Main Methods:

  • Prospective evaluation of 70 children with clinically suspected acute appendicitis over a 4-month period.

  • High-resolution ultrasonography was used to assess appendix compressibility and diameter.
  • Diagnostic criteria included a noncompressible appendix with a maximal outer diameter > 6 mm.

    • Main Results:

    • US correctly identified acute appendicitis in 31 of 35 confirmed cases (sensitivity 94%).
    • US showed a specificity of 89% for acute appendicitis, correctly ruling out the condition in 35 patients.
    • Seventeen patients with negative US findings for appendicitis were diagnosed with other conditions, including mesenteric adenitis and ileitis.

    Conclusions:

    • High-resolution ultrasonography is a highly accurate imaging modality for diagnosing acute appendicitis in children.
    • US demonstrates comparable diagnostic accuracy in pediatric patients to that reported in adult series.
    • The use of US can facilitate earlier diagnosis, reduce perforation rates, and decrease complications in pediatric appendicitis.
