Accuracy and Sensitivity of RIPASA Score in Diagnosis of Acute Appendicitis

Abstract

Background: The most frequent ailment requiring immediate surgical intervention is acute appendicitis. Up to 20% of patients had appendicular perforation, which raises the death and morbidity rates from 3% to 47%. Consequently, even in situations when there is even a low degree of suspicion, the appendix is routinely removed, which results in needless surgery for up to 40% of patients.Objective: To evaluate the sensitivity and diagnostic accuracy of Raja Isteri Pengiran Anak Saleha appendicitis(RIPASA)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 were reported with a cut off value of 7.5 and correlated to the postoperative histopathology. Results: Mean RIPASA Score was 10.2 ± 2.3. 9.85% were negative histologically for acute appendicitis. True positive was 170 cases. True Negative cases were 13. The sensitivity of RIPASA score was 96.5%, while the specificity was 76.4%. Diagnostic Accuracy was 94.8%. Conclusion: The RIPASA score is an accurate, practicable, and reliable diagnostic tool for acute appendicitis (AA) that also has a high sensitivity, positive predictive value, and diagnostic accuracy. Using a RIPASA score as a reliable diagnostic tool for acute appendicitis (AA), in Egyptians is possible when using a cutoff value of 7.5.
