Abstract
Abstract: Appendicitis represents one of the most common causes of abdominal pain and is the most common emergent surgical condition of the abdomen. Timely diagnosis and treatment of appendicitis is necessary to reduce the risk of perforation which is associated with increased morbidity and mortality. Objective of the study is to determine the accuracy of the ultrasonographic examination in cases of appendicitis confirmed with that of surgeon's post-operative findings. A total number of 100 patients (56 men and 44 women) selected by non-probability convenience sampling over a period of 8 months, with the clinical suspicion of appendicitis, were subjected to abdominal ultrasonographic examination. Ultrasound positive cases were subjected to surgery. The accuracy of ultrasonography in the diagnosis of appendicitis was compared withclinical diagnosis and post-operative findings. Out of 100 cases that underwent ultrasonography, 74 cases were sonographically positive for appendicitis and 16 cases were negative. The overall specificity of ultrasound was 56.52% and the sensitivity was 96.1% in the diagnosis of acute appendicitis, with PPV, NPV of 88.1% and 81.25. Overall accuracy was 87%. Conclusion: Acute appendicitis is a common indication for emergency abdominal surgery. Ultrasonography is still a useful tool in the diagnosis of acute appendicitis in spite of sophisticated investigations like CT abdomen and laparoscopy; thus, reducing the cost of treatment and preventing negative laparotomies.
