PAPS PaperBenchmarking the value of ultrasound for acute appendicitis in children
چکیده انگلیسی

BackgroundThis study appraises the diagnostic quality of ultrasound for acute appendicitis in children and consequently challenges the perception of inferior accuracy and suitability compared to computed tomography (CT).MethodsRadiologist reports for consecutive “query appendicitis” ultrasound studies were retrieved from a hospital database for the study period 2009-2014. Children who subsequently underwent appendicectomy were identified. Corresponding operative and histopathology findings were evaluated. Diagnostic accuracy of ultrasound was determined by analyzing overall accuracy, sensitivity, specificity, predictivity, and likelihood ratios.ResultsA total of 3799 ultrasound examinations were evaluated. Mean age was 11.5 ± 3.8 years. The proportion of patients investigated with preoperative ultrasound was 59.9% (1103/1840). Appendix visualization rate was 91.7%. Overall diagnostic accuracy was 95.5%. Sensitivity and specificity values were 97.1% (95.9-98.1; 95% CI) and 94.8% (93.9-95.6; 95% CI), respectively. Separate analysis of only ultrasound positive and negative examinations (i.e., excluding nondiagnostic examinations) confirmed sensitivity and specificity values of 98.8% and 98.3%.ConclusionIn this largest reported single institution series of ultrasound examinations for appendicitis, we report benchmark standard quality of diagnostic accuracy and visualization rates. Given the radiation and cost implications of CT, there is a strong argument to recommend ultrasound as the primary imaging modality.Diagnostic Study-Level II.
