Abstract :

Acute appendicitis remains the leading cause of abdominal pain and the most common indication for emergency operation. Prompt diagnosis of acute appendicitis is rewarded by a marked decrease in morbidity and negative laparotomies. Ultrasound is a widely used initial radiological investigation for the diagnosis of acute appendicitis, its utilization remains controversial and the decision for surgical intervention is still primarily based on precise clinical criteria. This study is done to establish the role of ultrasound in diagnosis of acute appendicitis. Diagnostic role of ultrasound was evaluated by calculating sensitivity, specificity, positive predictive value, negative predictive value and overall diagnostic accuracy. Total of 132 patients were included in the study during the study period of one year, i.e., September 2015 to September 2016. Those cases with alternate diagnosis were followed up and proved with other means of investigation. The sensitivity, specificity, positive predictive value and negative predictive value of ultrasound scanning with reference to histopathological confirmation was 95.58 % , 89.47 %, 98.18% and 77.27% respectively.
