Özet

BACKGROUND: The Karaman score is a novel diagnostic scoring system consisting of 6 parameters. The aim of the present study was to assess the diagnostic performance of the Karaman score in comparison with the Alvarado score. METHODS: A total of 200 patients who underwent an appendectomy were enrolled in the study (research registry number: 2290). RESULTS: The cutoff threshold of the Karaman score in distinguishing acute appendicitis from negative appendectomy was ≥9 with 84.3% sensitivity, 64.7% specificity, 92.1% positive predictive value (PPV), and 45.8% negative predictive value (NPV). The cutoff threshold of the Alvarado score in distinguishing acute appendicitis from negative appendectomy was ≥8 with 72.9% sensitivity, 70.6% specificity, 92.4% PPV, and 34.8% NPV. In multivariate logistic regression analysis, an Alvarado ≥8 score (Odds ratio [OR]:6.644, 95% confidence interval [CI]: 2.854–15.466; p<0.001) and a Karaman ≥9 score (OR:10.374, 95% CI: 4.383–24.558; p<0.001) were each individually predictive in distinguishing acute appendicitis from negative appendectomy when correction was made according to age and gender. However, when both scores were evaluated together, the Alvarado score ≥8 lost its efficacy (OR:1.838, 95% CI: 0.517–6.530; p=0.347), whereas the Karaman score ≥9 retained its predictive power (OR:6.586, 95% CI: 1.893–22.917; p=0.003). CONCLUSION: The Karaman score was more predictive than the Alvarado score in distinguishing acute appendicitis from a negative appendectomy.
