Abstract
Objective: Correlation of Ultrasound and RIPASA scoring system in the diagnosis of acute appendicitis. Study Design: 50 patients presenting to emergency underwent ultrasound and evaluation as per RIPASA scoring system followed by emergency appendicectomy. The sensitivity, specificity, positive and negative predictive value calculated for each group. Results: The sensitivity, specificity, Positive Predictive Value, and Negative Predictive Value for ultrasound were 75.51%, 100%, 100%, and 7.69% respectively, and that for the RIPASA scoring system were 93.9%, 100% 100%, and 25% respectively. The negative appendicectomy rate was 2%. Conclusion: RIPASA scoring system may be used for correctly diagnosing acute appendicitis but the low sensitivity of ultrasound precludes its routine use and may be used as a complementary tool in diagnosing acute appendicitis. Keywords: Acute Appendicitis, RIPASA, Ultrasound.
