Abstract :

OBJECTIVE. To determine the sensitivity and specificity of sonography in diagnosing acute appendicitis in patients with abdominal pain. METHODS. All reports relating to appendicitis were retrospectively obtained from archived reports of our department between Agust 2018 to December 2019 and correlated with the histopathology reports. RESULTS. Sonography reports for 667 patients were obtained. Of these, a total of 174 had pathologically proven appendicitis and 145 had posiitive findings for appendicitis on sonography. The accuracy was 92%; sensitivity, 83%; and specificity, 95%. The positive predictive value was 86%, and the negative predictive value was 94%. CONCLUSION. The sensitivity, specificity, accuracy, positive and negative predicative values of sonography are comparable to statistics quoted in the literature. The most common error was the tendency to misclassify appendixes < 6 mm.
