  • Description: Background: acute appendicitis is still a diagnostic and therapeutic challenge. Objective: to determine the tomographic variables independently of acute appendicitis.Method: a retrospective observational case-control study was carried out with a universe of 200 patients with suspected acute appendicitis at the Cuban Hospital of Qatar, from January 2018 to December 2019. The sample was made up of 80 patients, 27 cases and 53 controls. The following variables were studied: diameter, wall thickness, post-contrast enhancement of the wall, absence of oral contrast in the lumen, presence of fecaliths and periappendicular fat edema. The results were analyzed using frequency for qualitative variables and sample mean with standard deviation for quantitative variables, bivariate analysis by means of the chi-square test; multivariate analysis using binary logistic regression.Results: for the case group the average age was 33,6 years, the diameter of the appendix was 12,7 mm and the wall thickness was 3,7 mm. In the bivariate analysis diameter, wall thickness, periappendicular edema, appendicolith, post-contrast enhancement of the wall and absence of oral contrast in the lumen were significant. The multivariate analysis showed that a wall thickness of more than 3 mm and the absence of oral contrast in the lumen were independent and multiply the probability of acute appendicitis in 24,2 and 17,4 times, respectively.Conclusions: the wall thickness and the absence of oral contrast in the lumen of the appendix have independence on the diagnosis of acute appendicitis.
