Insights
Pediatric emergency physicians can accurately diagnose acute appendicitis in children using focused ultrasonography. This bedside sonography approach demonstrates high sensitivity and specificity for appendicitis detection.
Area of Science:
- Pediatric Emergency Medicine
- Diagnostic Imaging
- Ultrasound Technology
Background:
- Acute appendicitis is a common surgical emergency in children.
- Accurate and timely diagnosis is crucial to prevent complications.
- Pediatric emergency departments often rely on advanced imaging, but bedside ultrasound offers a rapid alternative.
Purpose of the Study:
- To evaluate the diagnostic accuracy of focused right lower-quadrant sonography performed by pediatric emergency physicians for acute appendicitis in children.
- To assess the effectiveness of a structured training program on physician sonography skills for appendicitis.
Main Methods:
- Prospective enrollment of children with suspected appendicitis in an urban pediatric emergency department.
- Pediatric emergency physicians performed focused ultrasonography using a graded-compression technique after standardized training.
- Sonographic interpretations were compared against clinical, radiologic, and pathological findings.
Main Results:
- 13 physicians performed 264 ultrasonographic studies; 85 (32%) were confirmed appendicitis cases.
- Bedside sonography achieved 85% sensitivity (95% CI 75%–95%) and 93% specificity (95% CI 85%–100%).
- Positive and negative likelihood ratios were 11.7 and 0.17, respectively, indicating strong diagnostic utility.
Conclusions:
- Focused ultrasonographic training enables pediatric emergency physicians to diagnose acute appendicitis with substantial accuracy.
- Bedside sonography is a valuable tool for the rapid evaluation of appendicitis in pediatric emergency settings.
- This approach can potentially improve diagnostic efficiency and patient outcomes.
Study Objective:
We investigate the accuracy of pediatric emergency physician sonography for acute appendicitis in children.
Methods:
We prospectively enrolled children requiring surgical or radiology consultation for suspected acute appendicitis at an urban pediatric emergency department. Pediatric emergency physicians performed focused right lower-quadrant sonography after didactics and hands-on training with a structured scanning algorithm, including the graded-compression technique. We compared their sonographic interpretations with clinical and radiologic findings, as well as clinical outcomes as defined by follow-up or pathologic findings.
Results:
Thirteen pediatric emergency medicine sonographers performed 264 ultrasonographic studies, including 85 (32%) in children with pathology-verified appendicitis. Bedside sonography had a sensitivity of 85% (95% confidence interval [CI] 75% to 95%), specificity of 93% (95% CI 85% to 100%), positive likelihood ratio of 11.7 (95% CI 6.9 to 20), and negative likelihood ratio of 0.17 (95% CI 0.1 to 0.28).
Conclusion:
With focused ultrasonographic training, pediatric emergency physicians can diagnose acute appendicitis with substantial accuracy.
