| Popis: | Background: U ltrasonographic scores for appendicitis to determine if, combined with Alvarado scores, they can increase the sensitivity and specificity of the diagnosis of appendicitis. Methods: All cases of abdominal pain suggestive of appendicitis presented between 2013 and 2015 were analysed. An Alvarado score was obtained. All patients underwent ultrasound, and an ultrasonographic score was determined, including the appendicitis classical findings. Results: Two hundred and fifty-one patients with abdominal pain in the right lower quadrant were analysed. Appendicitis was confirmed in 211 (84%) patients. For these patients, the average Alvarado score was 7.95/10 (±1.25) vs. 5.7/10 (± 1.11) for patients who did not have appendicitis (p < 0.001). In patients with confirmed appendicitis, the average ultrasonographic score was 2.48/6 (± 1.06) vs. 0.6/6 (± 0.92) for patients who did not have acute appendicitis (p < 0.001). The ultrasonographic score has a sensitivity of 90% and a specificity of 87% with only two parameters. The combination of the Alvarado and ultrasonographic scores decreased the percentage of negative appendectomies to 2.36% and increased the area under the curve by 0.970. Conclusions: The sum of the Alvarado and ultrasonographic scores provides an efficient alternative for diagnosing abdominal pain suggestive of appendicitis and predicts which patients should undergo surgery with good certainty. |
