Introduction Acute appendicitis is the most common surgical disease in emergency surgery, however, it remains a diagnostic problem and represents a challenge despite the experience and the different clinical and paraclinical diagnostic methods. Objective To evaluate in a comparative way the scale of Alvarado, AIR and RIPASA to determine which one is best as a diagnostic test of acute appendicitis in our population in order to arrive to an accurate diagnosis in the shortest possible time and cost. Method Observational, prospective, transversal and comparative study of 137 patients to whom the scale of Alvarado, AIR and RIPASA was applied, who entered the emergency service of the Civil Hospital of Culiacan (Mexico) with abdominal pain syndrome suggestive of acute appendicitis. Results The Alvarado scale presented sensitivity 97.2% and specificity of 27.6%. AIR presented sensitivity of 81.9% and specificity of 89.5%. RIPASA showed the same results as Alvarado. All tests showed diagnostic accuracy above 80. Conclusions Alvarado and RIPASA presented good sensitivity, however, AIR is more specific, and has better accuracy for the diagnosis of acute appendicitis, making a better screening and thus reducing unnecessary surgeries. Therefore, it is recommended to use more AIR than Alvarado and RIPASA. |
