Respuesta del score RIPASA versus el histopatológico como predictor diagnóstico de apendicitis aguda en el Hospital Vicente Corral Moscoso año 2018

Abstract

Background: Acute Appendicitis (A.A) is a surgical emergency that requires timely diagnosis and treatment. Many times it can be a great challenge for the surgeon because of its relationship with other pathologies, hence the importance of specifying its diagnosis. Objective: To validate the diagnostic accuracy of the RIPASA score in acute appendicitis by comparing it with the histopathological examination. Methodology: A study of validation of diagnostic tests was carried out with the information of 300 medical records of appendectomized patients, treated at the Vicente Corral Moscoso Hospital during 2018. It was evaluated by means of the RIPASA score at admission and compared with the histopathology results. as gold standard test. Sensitivity, specificity, positive predictive value, negative predictive value were calculated, in addition Odds Ratio was obtained with its 95% CI to establish the predictive validity of this scale. Results: The mean age was 32 years ± 13.7 (SD), more than half were: female 52%, urban area 74.7% and high school 62.7%, mixed race ethnicity predominated 99.7%. There was a risk association between a high probability of appendicitis according to the RIPASA score with A.A (OR 96.36; 95% CI: 16.03–578.68; p = 0.000). The RIPASA score has a sensitivity of 98.97%, specificity 50.0%, PPV 98.63%, NPV 57.14%, RVP 1.8% and RVN 0.2% Conclusions: RIPASA has a high probability of detecting people with acute appendicitis, but not healthy ones, so it is necessary to continue with more studies to find such validity
