Abstract: Introduction: Acute appendicitis is one of the most common surgical emergencies. Various scoring systems have been developed for supporting the diagnosis of acute appendicitis. The most common and widely applied scoring system is Modified Alvarado Scoring system. The RIPASA Score, a new diagnostic scoring system developed for the diagnosis of Acute Appendicitis has shown significantly higher sensitivity, specificity and diagnostic accuracy compared to Alvarado Score, particularly in Asian population.
Aims and Objectives
1)To compare RIPASA Score and Modified Alvarado Score in the diagnosis of acute appendicitis.
2)To assess the accuracy of RIPASA Score and Modified Alvarado Score as reliable indicator for Appendicectomy surgeries and attenuating the “Negative Appendicectomy” rates.
Materials and Methods: 68 clinically suspected cases of acute appendicitis, admitted in the surgical wards of Mamata General Hospital, were included in the study after obtaining their consent. Every patient was scored with both scores after taking detailed history, clinical examination and relevant investigations. A score of >7 for Modified Alvarado scoring system and >7.5 for RIPASA scoring system was taken as high probability of acute appendicitis. Following the data compilation sensitivity, specificity and accuracy of Modified Alvarado and RIPASA scoring systems for diagnosing acute appendicitis were calculated and compared.
Results: With the cut-off value greater than 7.5 for RIPASA score; sensitivity, specificity, positive predictive value, negative predictive values were 100%, 23.08%, 84.62% and 100% respectively. With the cut-off value greater than 7 for Modified Alvarado score sensitivity, specificity, positive predictive value, negative predictive values 80.00%, 76.92%, 93.62%, 47.62% respectively. Diagnostic accuracy of RIPASA and Modified Alvarado score were 86.24% and 79.41% respectively.
Conclusion: RIPASA score was better than Modified Alvarado score in diagnosing acute appendicitis.
