Purpose: The aim of this study is to compare the efficiencies of Alvarado score and ultrasonography in diagnosis of acute appendicitis Material and Methods: Two hundred and eleven patients who applied to emergency service with complaint of right lower quadrant pain between January 2013 and February 2015, were retrospectively examined. Twenty two patients, where the pathologies other than appendicitis were determined and no ultrasonography was applied, were excluded from the study. The Alvarado scores of the patients were calculated and recorded. They were divided into 2 groups by the Alvarado score; the scores <7 and those ≥7.  Results: Of 189 patients involved in this study, 157 patients (83%) had acute appendicitis and 32 (17%) had normal appendix. There were 68 patients (35.9%) having Alvarado score <7 and 121 patients (64.1%) having Alvarado score ≥7. Specificity of Alvarado score was calculated to be 90.6%, sensitivity to be 75.1%, positive predictive value to be 97.5%, negative predictive value to be 18.4%, and accuracy rate to be 77.7%. The specificity of ultrasonography was calculated to be 62.5%, sensitivity to be 74.5%, positive predictive value to be 90.6%, negative predictive value to be 12.7%, and accuracy rate to be 72.4%. Conclusion: Alvarado scoring system and ultrasonography are the effective tools that can be used in diagnosis of acute appendicitis. But, however, Alvarado system come to the forefront as a more sensitive system. Among the patients having Alvarado score ≥ 7 and ultrasonographically diagnosed to have appendicitis, it would be better to use these methods together.
