Accuracy and sensitivity of RIPASA score Versus Alvarado score in diagnosis of acute appendicitis.

Abstract

Background: Acute appendicitis (AA) is a prevalent emergency involving the abdomen that necessitates prompt attention and has a significant risk of negative appendectomyObjective: To compare the sensitivity and diagnostic accuracy of RIPASA and Alverado scoring systems of acute appendicitis in correlation with intra-operative findings.Patients and Methods: This prospective study included 193 patients with acute appendicitis All items of RIPASA score and Alverado score were reported with a cut off value of 7.5 for RIPASA and 7 for Alverado and correlated to the postoperative histopathology. Results: The mean age of the included patients was 33.25 ± 11.39 years. The histopathological outcome in correlation to RIPASA score 84% of cases were true positive while 8.3% were true -v while the correlation with Alverado score 73% of cases were truly +ve and 12.4% were truly _ve. there was statistically significant difference between both RIPASA and Alverado scores where RIPASA score was significantly more sensitive and accurate than Alverado with Higher NPV while Alverado score was more specificConclusion: According to the current results, RIPASA score is a reliable, feasible for Diagnosis of AA with high sensitivity, positive predictive value, and Diagnostic accuiracy in comparison with the Alverado score.
