| Popis: | BACKGROUND Comparing the diagnostic accuracy of RIPASA score over Alvarado score in diagnosing acute appendicitis. The accuracy of Alvarado score in the diagnosis of acute appendicitis is disappointingly low in Asian population and RIPASA scoring has been designed for the diagnosis of acute appendicitis in the Asian population. MATERIALS AND METHODS A cross-sectional study of 109 patients diagnosed to have acute appendicitis with the aim of comparing RIPASA and Alvarado scoring. A score of 7.5 is the optimal cut off threshold for RIPASA and 7 for Alvarado scoring system. Sensitivity, specificity, positive predictive value and negative predictive for RIPASA and Alvarado system were done. RESULTS The sensitivity and specificity of RIPASA score were 95.5% and 65%, respectively. The sensitivity and specificity of Alvarado score were 65.16% and 90%, respectively. The positive predictive value of RIPASA was 92.39% and negative predictive value 76.47%. The positive predictive value for Alvarado was 96.6% and negative predictive value was 36.73%. RIPASA score correctly classified 89.9% of all patients confirmed with histological acute appendicitis to the high probability group (RIPASA score greater than 7.5) compared with 69.73% with Alvarado score (Alvarado score greater than 7.0; p-value is 0.002). CONCLUSION RIPASA scoring system is more convenient, accurate and specific scoring system for Indian population than Alvarado scoring system |
