Abstract

Objective: to determine the validity of the scale of Alvarado and criteria of systemic inflammatory response syndrome for complicated acute appendicitis in the emergency area of surgery Vicente Corral Moscoso Hospital. Materials and Methods: a validation study was performed diagnostic test, the sample was 360 patients attending from January to November 2014 and the emergency area who met the inclusion criteria; a questionnaire was applied. Database with the ROC curve, sensitivity and specificity of the variables was obtained. Program Excel 2010 and SPSS version 15 was used. Results: acute appendicitis complicated according to histological result was found in 27.2% (n = 98) and presented an average evolution time 30 hours 50 minutes (p = 0.00). Alvarado score with a score of 7-10 had a sensitivity of 100% and a specificity of 20.2% for the diagnosis of acute apendicitis complicate, SIRS criteria had sensitivity and specificity of 68% and the time evolution of the pain again specificity of 81%. The ROC curve Alvarado score, SIRS and the time evolution of pain had an area larger than the value of 0.5. Conclusions: the diagnosis of acute apendicitis complicate may be suspected when the scale of Alvarado, SIRS criteria are high and the time evolution of the pain is prolonged
