Role of Graded Compression Ultrasonography in Suspected Cases of Acute Appendicitis and its Surgical Correlation: A Prospective Study

Aim: The aim of the study was to evaluate the role of Ultrasonography in suspected cases of acute appendicitis and its correlation with surgical findings. Material and methods: Fifty patients over a period of 18 months who were suspected of acute appendicitis were studied and subjected to ultrasound examination. Those found positive on ultrasound were operated and findings were compared with ultrasound reports. Sensitivity and specificity, PPV, NPV and accuracy was calculated. Results: After comparing the findings the sensitivity was found to be 92.6%, specificity 100%, accuracy 94%, PPV 100% and NPV 75%. These values were then compared with various others studies. Conclusion: Ultrasound is a safe, inexpensive, non invasive, quick to perform method for the diagnosis of acute appendicitis thereby, reducing the cost of treatment and preventing negative laparotomies.
