Introduction and Objective:

Acute appendicitis is one of the frequent emergency surgical pathologies, the diagnosis is mainly clinical and if it is late it has a high risk of complications. The present study seeks to see the diagnostic utility of the Alvarado criteria for acute appendicitis at the Japanese Bolivian Gastroenterological Institute- La Paz during the year 2019.

Material and Methods:

A prospective, descriptive cross-sectional study was carried out at the IGBJ - La Paz, a questionnaire was developed for a semi- structured interview with inpatients with suspected acute appendicitis.

Results:

The study included 54 patients, of whom 64.8% were men and 35.2% were men. The test for acute appendicitis with a value greater than 7 had a sensitivity of 90% and a specificity of 50%, so appendicitis cannot be ruled out since 50% is a low value, with a positive predictive value of 96% and negative predictive value of 29%, when making a cut of 9 or more for diagnosis of complicated acute appendicitis had a sensitivity of 63% and specificity of 67%, positive predictive value of 81%, negative predictive value of 43%.

Conclusions:

We conclude that the Alvarado Criteria is a useful tool for the diagnosis of cases of complicated appendicitis; but not all variables are useful for diagnosis, the most representative are pain in the right iliac fossa and rebound, therefore the use of the scale is recommended in emergency services.
