Diagnostic value of the reason neutrofilos-lymphocytes identify complicated acute appendicitis

Objetive: Determine the diagnostic value of the Ratio Neutrophils Lymphocytes (RNL) in complicated appendicitis for patients Almanzor Aguinaga Asenjo National Hospital. Material and Methods: Quantitative, non-experimental, descriptive study of 220 medical records of patients diagnosed with acute appendicitis coincided with the study inclusion criteria. Results: 121 men (55%) was found. The median for age was 25.4 years, 36.96 hour to time disease, 15.84 hours to time to surgery, 5.44 days to time of stay in hospital and 8.84 to RNL. 105 complicated appendicitis (47.7%), 4 normal appendices (1.8%) was found. The ROC curve for RNL gave an AUC = 0.84 (p <0.05, 95% CI = 0.786 to 0.894). A specificity of 84.3% (95% CI = 76.6% - 89.9%) - a sensitivity of 78.1% (84.9% CI 95% = 69.3%) was observed, PPV of 82.0% (95% CI = 73.3% - 88.3%), VPN 80.8% (95% CI = 72.9% - 86.9%), accuracy of 81.4% (95% CI = 75.7% - 86.0%), Odd Radio Diagnostic 19.21 (95% CI = 9.70 to 38.05), CPP 4.99 (95% CI = 3.23 to 7.72), CPN 0.26 (95% CI = 0.18 to 0.38) and J Youden index of 0.6244; for RNL >= 6.0 value. Conclusions: The RNL >= 6.0 is associated with complicated appendicitis and seems to be a good diagnostic tool subordinated to the clinical examination.
