Efficacy of the Modified Alvarado Scoring System and Radiologic Studies in Diagnosing Appendicitis in Children: A Retrospective Comparative Study

This study highlights the potential of the MAS as a valuable tool for the initial assessment of appendicitis in children, demonstrating high sensitivity and NPV. Although it has a moderate PPV and specificity, suggesting efficacy in ruling out appendicitis, it should be supplemented with radiologic findings for a definitive diagnosis. Tenderness remains a crucial clinical sign, emphasizing its importance on physical examination. These findings should guide future research to refine the MAS components and explore complementary diagnostic strategies to improve the accuracy of pediatric appendicitis diagnosis.
