The purpose of this study was to apply both scales in the emergency apendicits 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.

Distribution of the Variables of the Patients Included.

Postoperative complications occurred in 8 patients 4 seromas, 2 infections of the surgical site and 2 residual abscesses.

In order to avoid delay in the diagnosis of acute appendicitis and reduce the margin of error, the use of scales has been used. We defined residual abscess as the presence of intra-abdominal purulent collections after the surgical treatment of AA.

A descriptive statistical analysis of the demographic data of the population was completed, as well as the analysis of diagnostic tests, using the pathology report as a gold standard sensitivity, specificity, positive predictive value [PPV], negative predictive value [NPV].


The result consists of the sum of the values, with a maximum score of Then we approached the task of calculating the positive LR for each comparative report Table 4and the average of these studies was slightly higher 3.

The further away from 1, the better the test is to differentiate between sick and healthy subjects.

APENDICITIS by Gustavo Rondon on Prezi

A new adult appendicitis score improves diagnostic accuracy of acute appendicitis – a prospective study Henna E. After patients were discharged, they were followed-up in the outpatient setting for at least 30 days.

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 patients were included. Are negative appendectomies still acceptable?. One of the researchers was responsible for coding patient data, using numbers instead of names.

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, apehdicitis the probable diagnosis of AA was basically clinical as was the decision to carry out the surgical aguds. 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.

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. 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 Alvaeado de Alta Especialidad of Veracruz with suspected diagnosis of AA and underwent appendectomy. The differences observed between both scores were not statistically significant.


More than one patient presented more than one comorbidity.


Excess weight and obesity. JAMA,pp. Different scoring systems have been created to increase diagnostic accuracy, and they are inexpensive, noninvasive, and easy to use and reproduce. Cancer risks attributable to low doses of ionizing radiation: We compared the sensitivity results of both classifications between patients with appendicitis; likewise, among patients without appendicitis we compared the results in terms of specificity McNemar’s test for paired data.

An adequate clinical scoring system would avoid diagnostic errors, maintaining a satisfactory low rate of negative appendectomies by adequate patient stratification, while limiting patient exposure to ionizing radiation, since there is an increased risk of developing cancer with computed tomography, particularly for the alvafado age group. Lancet,pp. Showing of 15 references.

The variability alvarafo figures observed between the studies may also be secondary to an effect of the population from which the sample was extracted.
