Abstract

Background: Diagnosing Acute Appendicitis presents challenges due to numerous differential diagnoses. Postponement in management may lead to increased mortality and morbidity rates, as clinical diagnosis entails a considerable chance of negative appendectomy, with literature reporting an incidence as high as 23%.
Objectives: To assess the diagnostic efficacy of the Adult Appendicitis Score in cases with Acute Appendicitis.
Methods: Prospective clinical research was implemented for 6 Months. One hundred patients with Right iliac pain and appendicitis who couldn't be excluded were recruited and subjected to Clinical and Lab. Based on a scoring system (Adult Appendicitis score).
Results: AAS showed a significantly higher sensitivity (91.3% vs. 81.5%), specificity (18.5% vs. 8.7%), and negative predictive value (NPV) (71.4% vs. 28.65%) but lower positive predictive value (PPV) (48.8% vs 51.2%).
Conclusion: The diagnosis of acute appendicitis is a complex endeavor in the absence of radiographic validation. AAS has exhibited superior accuracy, particularly in recognizing patients eligible for Discharge from the emergency room. These data indicate that AAS diminishes the dependency on radiological imaging and more effectively lowers the incidence of negative appendicitis.
