Immature Granulocyte Percentage as an Early Predictor of Necrosis in Volvulus

Abstract

ABSTRACT Aim: Volvulus is a disease characterized by the abnormal twisting of a gaseous distension of the loop of the intestine around itself. Colonic volvulus is the third common cause of colonic obstruction. The study aimed to determine whether the percentage of immature granulocytes is a marker of early necrosis in the volvulus. Methods: Demographic characteristics of the cases were collected in the study. In addition, age, gender, white blood cell count, immature granulocyte count, immature granulocyte percentage, platelet lymphocyte ratio, and neutrophil-lymphocyte ratio were compared between groups with and without necrosis in terms of treatment. Results: The effectiveness of immature granulocyte percentage (IG%) and IG markers were statistically significant in predicting necrosis. The AUC was the highest for IG (0.820, 95% CI: 0.586–1), followed by IG% (0.820, 95% CI: 0.617–1). The optimal cut-off value for the IG was 0.65, with a sensitivity of 76.2% and specificity of 85.7% (P = 0.013). The optimal cut-off value for the IG% was 0.065, with a sensitivity of 85.7% and specificity of 71.4% (0.018). Conclusion: IG% and IG count were found to be useful for predicting necrosis in patients with volvulus.
