Guardiola aEnrique A. The variability of figures observed between the studies crietrios also be secondary to an effect of the population from which the sample was extracted. With these data, ROC curves were generated to compare both scores. You can change the settings or obtain more information by clicking here. Are you a health professional able to prescribe or dispense drugs? We defined residual abscess as the presence of intra-abdominal purulent collections after the surgical treatment of AA.

Prospective evaluation of the ability of clinical scoring systems and physician-determined likelihood of appendicitis to obviate the need for CT. Prospective, longitudinal, analytical, comparative and observational study. 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 ccriterios not been able to reduce the percentage of diagnostic error.

The average hospital stay was 3. 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.

Emerg Med J, 33pp. A comparison with the modified Alvarado score. 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.

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. Cancer risks attributable to low doses of ionizing radiation: High negative appendectomy rates are no longer acceptable. The body mass index is calculated by dividing weight in kilos by height squared in meters.


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

Edematous appendicitis was observed in 2 cases, phlegmonous appendicitis in 30 patients, necrotic appendicitis in 21, and perforated appendicitis in 33 cases. The 2 different classifications, the Alvarado and the RIPASA scores, were applied to each of the patients by a resident doctor in surgery, without influencing the surgeon’s decision regarding surgical intervention.

Leukocytosis higher than 10 The pathology report was obtained and the efficacy of both scores for the diagnosis of acute appendicitis was compared. JavaScript cgiterios disabled for your browser.

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.

ROC curves obtained by calculating the results of both scores. The result consists of the sum of the values, with a maximum score of Update on the Management of Non-obstetric Acute Abdomen in Apendjcitis Alvarado system includes 3 symptoms, 3 physical signs and 2 laboratory parameters; each variable is assigned a value of 1 or 2 points.

Afterwards, we calculated the likelihood ratio. One hundred patients were included. KanumbaJoseph B.

Show full item record. The Alvarado paendicitis published in is an assessment chart Table 1whose sum gives a maximum of 10 points with a higher probability that the patient has AA.

The anatomopathological diagnosis constituted the Standard Crkterios in this study. J Evid Based Med Healthc, 3pp. ROC curves were generated Fig. One billion dollars are spent each year on negative appendectomies, 4,5 so high rates of negative appendectomies are no longer acceptable.
