Abstract
Objective: To determine the diagnostic accuracy of
RIPASA score in acute appendicitis compared to
modified Alvarado score.
Methodology: The study included 65 patients who
underwent appendectomy. The histopathological
assessment was done and compared with the scores for
diagnostic accuracy.
Results: The sensitivity of RIPASA score was 98.3%,
with specificity of 100%, a positive predictive value of
100%, and negative predictive value of 80%. The
Alvarado score had sensitivity and specificity of
65.6% and 75.0%, respectively.
Conclusion: We found that RIPASA was a better
scoring system in our population when compared to
modified Alvarado for the diagnosis of acute
appendicitis.
Keywords: RIPASA, modified Alvarado, acute
appendicitis, appendectomy.
