Diagnostic accuracy of abdominal ultrasound for detection if acute appendicitis taking operative findings as gold standard

Abstract

This study objective is to assess the diagnostic accuracy of ultrasonography (USG). While evaluating acute abdominal conditions, including acute appendicitis acute cholecystitis, and pneumoperitoneum. In this study, 342 patients were evaluated to present with symptoms suggestive of acute abdominal pathology. Researchers included patient data including demographic information and USG findings were collected from medical records. In addition, diagnostic accuracy parameters, including sensitivity, specificity, positive predictive value (PPV). Moreover, negative predictive value (NPV), and overall diagnostic accuracy of USG, stratifiend and calculated based on age and gender. The average age of the study was 41.23 ± 6.75 years with a gender distribution. Though the (male: 197, female: 145). USG demonstrated high diagnostic accuracy in detecting acute appendicitis (sensitivity 89.60%, specificity 82.50%. the PPV 88.89%, NPV 83.54%, diagnostic accuracy 86.83%). While the acute cholecystitis (sensitivity 94.44%, specificity 87.10%, diagnostic accuracy 91.04%), and pneumoperitoneum (sensitivity 95.35%, specificity 88.89%, PPV 93.18%, NPV 92.31%, diagnostic accuracy 92.86%). The Stratified analyses by age and gender revealed consistent diagnostic performance of USG. The findings of this study found the diagnostic utility of ultrasonography in evaluating acute abdominal conditions. These results underscore the importance of USG as a frontline imaging modality in the management of acute abdominal emergencies
