Different scoring systems have been created to increase diagnostic accuracy, and they are inexpensive, noninvasive, and easy to use and reproduce. Prospective, longitudinal, analytical, comparative and observational study.

In order to avoid delay in the diagnosis of acute appendicitis and reduce the margin of error, the use of scales has been used. JavaScript is disabled for your browser. In the study by Golden et al.

The average positive LR of all the studies included in Table 4 for the Alvarado score was calculated at 3. Topics Discussed in This Paper. The higher the score obtained, the greater the probability that the patient has AA. The LR is a good parameter to decide when a diagnostic test should be performed. The distribution of AA cases was similar to other reports, predominantly affecting patients between the second and fourth decades of life.

An analytical, observational study was conducted between June 1 and December 31, in patients of both sexes who were 18 years of age or older and came to the emergency department of the Hospital de Alta Especialidad of Veracruz with suspected diagnosis of AA and underwent appendectomy.

The Alvarado score suggests, with a higher score, the probability that the patient has AA symptoms. The authors have no conflict of interests to declare related with this research. The mean body mass index was Postoperative complications occurred in 8 patients 4 seromas, 2 infections of the surgical site and 2 critsrios abscesses. 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.

High negative appendectomy rates are no longer acceptable. The purpose of our study was to compare the ability of two clinical scoring systems, the Alvarado and the RIPASA scores, to diagnose or rule out appendicitis since computed tomography, ultrasound and laparoscopy have not been able to reduce the percentage of diagnostic error.

In all patients, complete analysis and urinalysis were requested; abdominal ultrasound was requested in 21 patients, in addition to abdominal X-rays, and in 66 patients only abdominal X-rays were requested, since the probable diagnosis of AA was basically clinical as was the decision to carry out the surgical intervention.

J Coll Physicians Surg Pak, 24pp. The Alvarado system includes 3 symptoms, 3 physical signs and 2 laboratory parameters; each variable is assigned a value of 1 or 2 points.

It should be mentioned that axial tomography is not a study that is routinely requested at our hospital in cases of suspected AA. Results One hundred parx were included. We performed an analysis for diagnostic tests sensitivity, specificity, positive predictive value, negative predictive value, false positive, false negative and comparative ROC curves for both scales.

Criterlos higher than 10 In contrast, Nanjundaiah et al. The pathology report was obtained and the efficacy of both scores for the diagnosis of acute appendicitis was compared. Usefulness of the Alvarado scoring system with respect to age, sex and time of presentation, with regression analysis of individual parameters. Application of alvarado scoring system in diagnosis of acute appendicitis.


Are negative appendectomies still acceptable?. Apendicitiss the handling of the data, confidentiality was maintained and patient anonymity was respected.

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. Singapore Med J, 52pp. Resultados Se incluyeron pacientes. Upon applying the grading systems to the patients in the study, we found that the RIPASA score showed greater diagnostic certainty compared to the Alvarado score, with a sensitivity of One hundred patients were included.

The average time between the onset of symptoms and the first medical assessment was ROC curves obtained by calculating the results of both scores. Singapore Med J, 51pp. The purpose of this study was to apply both scales in the emergency department in cases of patients with presumptive diagnosis of AA and to compare these with the pathology reports after appendectomy, thereby comparing the efficacy, sensitivity and specificity of the Alvarado and RIPASA scores in the diagnosis of AA at a tertiary hospital serving the population of eastern Mexico.

Continuing navigation will be considered as acceptance of this use. Within the studies comparing both systems Table 4Chong et al. Contact Us Send Feedback. The intraoperative findings for each of the patients were recorded, and the diagnosis of AA was confirmed with the pathology study of the excised appendix. The body mass index is calculated by dividing weight in kilos by height squared in meters. Introduction In order to avoid delay in the diagnosis of acute appendicitis and reduce the margin of error, the use of scales has been used.
