A Comparative Study of RIPASA and ALVARADO Scoring Systems in the Diagnosis of Acute Appendicitis

Senthil Kumar M [2] | Muralidharan [6] | Samara Simha Reddy


Abstract: Background: The objective of the study is to assess the RIPASA scoring system and the ALVARADO Scoring System for the diagnosis of Acute Appendicitis. Materials and methods: A prospective study was conducted on 60 patients aged between 18 to 60 years who presented with right iliac fossa pain clinically suspected to be acute appendicitis. Both the scores were calculated on all the patients. Depending on clinical judgment appendicectomy was done. Post operative histopathology report was correlated with the scores. A score of 7.5 is the optimal cut off threshold for RIPASA and 7 for Alvarado scoring system. Sensitivity, specificity, positive predictive value (PPV) and negative predictive (NPV) for RIPASA & Alvarado system was done. Results: The sensitivity and specificity of RIPASA score were 54.83% and 62.06% respectively. The sensitivity and specificity of Alvarado score were 58.9% and 85.7%. Conclusion: The present study concludes that, in the diagnosis of acute appendicitis, RIPASA score is more specific than Alvarado Score, and also has a higher Positive Predictive Value and Diagnostic Accuracy. RIPASA also reduces the number of "missed appendicitis" cases. Hence, RIPASA is clinically and statistically a better scoring system for the diagnosis of acute appendicitis than Alvarado score.
