Each patient was scored by both RIPASA and modified ALVARADO scores and Histopathological report for Appendicitis was taken as the gold standard. Both the scores were evaluated for their diagnostic ability.Results: 80 patients with suspected Acute Appendicitis with a mean age of 21.36 years and with female predominance were scored by both RIPASA and modified ALVARADO scores. Sensitivity, specificity, Positive and Negative predictive values, Positive and Negative likelihood ratio, and area under ROC curve for RIPASA score (at 7.5 cutoff) were 94.74, 82.61, 93.10, 86.36, 5.45, 0.06 and 0.93; corresponding values for modified ALVARADO score (at 7.0 cutoff) were 59.65, 82.61, 89.47, 45.24, 3.43, 0.49 and 0.89 respectively. Both the scores had positive correlation when diagnosing an Acute appendicitis patient.Conclusion: RIPASA Score (at 7.5 cut-off) is a better diagnostic tool than modified ALVARADO Score (at 7 cut-off) due to better sensitivity, Positive and Negative predictive values, and higher area under the fitted ROC curve.EnglishAcute Appendicitis, Modified ALVARADO score, RIPASA scorehttps://yemenjmed.com/admin/abstract?id=11References16191.and;nbsp;and;nbsp; and;nbsp;Chaochankit W, Boocha A, Samphao S.
