AbstractThe purpose of this study was to clarify the clinical features most closely associated with gangrenous appendicitis. From among 314 patients who had undergone open appendectomy in our collected database, 222 for whom sufficient data were evaluable were enrolled. The results of univariate analysis revealed that age (≤40/>40 years), sex (female/male), fever (≤37°/>37°C), the serum levels of C-reactive protein and albumin, the Glasgow prognostic score (0, 1/2), and the neutrophil-to-lymphocyte ratio (NLR) (≤8/>8) were associated with gangrenous appendicitis. Among these 7 clinical features, multivariate analysis disclosed that age (≤40/>40 years) (odds ratio, 3.435; 95% confidence interval 1.744-6.766; P < 0.001) and NLR (≤8/>8) (odds ratio, 3.016; 95% confidence interval 1.535-5.926; P = 0.001) were associated with gangrenous appendicitis. The sensitivity and specificity of these two clinical features were 65% and 27%, and 73% and 39%, respectively. NLR (>8) shows a significant association with gangrenous appendicitis in patients undergoing appendectomy.
