Background: Among acute emergencies, the most commonly occurring one is Acute appendicitis. Scoring systems have been
developed such as Alvarado and Modified Alvarado Scores. RIPASA Score has a higher sensitivity in the Asian population set.
Thus, came about the plan of our examination to try things out with this new score and to check whether it undoubtedly performs
wellto the undertaking.
Objectives To determine the sensitivity, specificity of the 16-point RIPASA scoring system in diagnosing suspected acute
appendicitis and its validationin correlation with histopathology.
Material and Methods: The study was carried out in Khyber Teaching Hospital Peshawar Pakistan from January 2018 to June
2018, Department of General Surgery. A total of 322 patients were included in the study. In ED, resident surgeons filled in the
RIPASA Score proforma by taking a detailed history and doing a physical examination, and running labs along with
ultrasonography. The decisionto perform appendectomy was solelytaken bythe senior registrar which was the final decision and
the sample was sent forH/P later on.
Results: Of the 322, patients who went through the surgery for acute appendicitis, 188 (58.4%) were male and 134 (41.6%) were
female, 284(88.2%) had positive histopathology reports and 38 (11.8%) had a negative report. The sensitivity of the RIPASA Score
at a cut-off value of 8.0 was 97.98%,with the specificity of 77%, and Positive Predictive value of 97.52%,and a Negative Predictive
Value of 86.3%.
Conclusion: The clinical implication of RIPASA score is found to be more beneficial than the traditional Alvarado scoring system,
thus could bringthe complications rates of appendectomy to significantly lowerfigures.
