The aim of this study was to compare the effectiveness of the Alvarado and RIPASA scores in the clinical diagnosis of acute appendicitis and to correlate with the histopathological results.

Has misdiagnosis of appendicitis decreased over time? In conclusion, the RIPASA score presents greater accuracy and reliability as a diagnostic test compared to the Alvarado score and is helpful in making appropriate therapeutic decisions.

Within the studies comparing both systems Table 4Chong et al. Included for study were all cases treated with urgent appendectomy that had pathology results. Resultados Se incluyeron pacientes. In contrast, Nanjundaiah et al. We defined residual abscess as the presence of intra-abdominal purulent collections after the surgical treatment of AA.

With these data, ROC curves were generated to compare both scores. Emerg Med J, 33 agufa, pp. Showing of 15 references. Skip to search form Skip to main content. In the case of our study, the positive LR was 3. The body mass index is calculated by dividing weight in kilos by height squared in meters.

The pathology report was obtained and the efficacy of both scores for the diagnosis of acute appendicitis was compared. The anatomopathological diagnosis constituted the Standard Gold critwrios this study. Rev Hosp Juarez Mex, 76pp. Ann Emerg Med, 64pp. Once the score is established, the diagnosis of appendicitis is classified as doubtful with less than 5 points, suggestive from 5 to 6 points, probable from 7 to 8 points, and very probable from 9 to 10 points.

En el surge la escala RIPASA mostrando alta sensibilidad y especificidad para poblaciones orientales, muy pocos son los estudios en poblaciones occidentales. Distribution of the Variables of the Patients Included. Several scoring systems have been developed for the early and equivocal diagnosis of this entity, one of these scales is the modified Alvarado, most used in the Western population; however, the RIPASA scale emerges in showing high sensitivity and specificity for Asian and Eastern populations, there are few studies in Western populations of this new scale.
