Abstract

Objective: Comparative study of Diagnostic accuracy of Modified Alvarado Score and Ultrasonography in Acute Appendicitis. Methods: A total of 798 patients of with all age group, both male and females, with clinical features suggestive of acute appendicitis were selected non-randomly for the study. Data was collected as Alvarado score, ultrasonograpic findings and histopathological reports. Statistical analysis was performed and results of both Alvarado score and Ultrasonography were compared. Results: Of 798 patients taken, maximum percentage of patients were in age group 21-30 yrs with males dominated the series. The sensitivity and specificity of alvarado score was 80.36% and 81.89% with PPV 91.02% and NPV 64.61% and diagnostic accuracy of 80.82% respectively. Ultrasonography study revealed 85.05% sensitivity and specificity of 51.02%,PPV and NPV were 79.86% and 59.90% and diagnostic accuracy was 74.68% respectively. Conclusions: The Alvarado score is better investigative tool than ultrasonography alone in diagnosis of acute appendicitis. [Kaushal S NJIRM 2017; 8(6):41-45]
