Predictive value of immature granulocyte and delta neutrophil index in the diagnosis of complicated acute cholecystitis

OBJECTIVE: The complicated gallbladder disorders are associated with increased mortality and morbidity. Thus, this study was aimed at evaluating the predictive value of immature granulocyte count and delta neutrophil index in the prediction of complicated cholecystitis.

PATIENTS AND METHODS: We retrospectively reviewed patients who underwent surgery for acute cholecystitis between January 2018 and April 2022. Overall, 351 patients fulfilling the inclusion criteria were included in the study. In all patients, demographic data, immature granulocyte count (IGC), delta neutrophil index (DNI), white blood cell (WBC) count, C-reactive protein (CRP), and albumin levels were recorded. Based on operative findings and histopathological examination, the patients were classified into 2 groups uncomplicated (group I) and complicated (e.g., perforation, gangrenous and emphysematous cholecystitis; group II) groups. The IBM SPSS version 26.0 (SPSS Corp, Armonk, NY, USA) was used to assess differences in blood parameters between groups. The predictive values of the parameters evaluated were estimated using ROC analysis. A p-value<0.05 was considered statistically significant.

RESULTS: Acute complicated cholecystitis was found in 138 of 351 patients. No significant difference was detected in age and gender distribution between groups (p=0.352 and p=0.214, respectively). When blood parameters were assessed, it was found that IGC, DNI, WBC, and CAR values were significantly higher in group II (p<0.001; p<0.001, p<0.001, and p=0.036, respectively), while there was no significant difference in CRP and albumin between groups (p=0.099 and p=0.53, respectively). In the ROC analysis, the highest AUC value was found for IG count and DNI (0.784 and 0.775, respectively). The sensitivity and specificity were found as 68.8% and 86.9% for IG count and 49.3% and 96.2% for DNI, respectively.

CONCLUSIONS: The IG count and DNI are two novel parameters with strong predictive value in the early diagnosis of acute complicated cholecystitis, which may support clinical findings, imaging studies, and other laboratory parameters.
