Predictive role of serum markers in the evaluation of acute abdomen

Introduction In this study, the hematological and inflammatory parameters of patients admitted to the emergency department with abdominal pain were examined and predictive values were determined. Methods A total of 12682 patients who applied to Sakarya Training and Research Hospital adult emergency service with abdominal pain between 01/01/2019-31/12/2019 were included in the study. Patients were divided into groups, as follows: Group 1: Patients discharged from the emergency room, Group 2: Patients who were hospitalized from the emergency department and discharged without surgery, Group 3: Patients who were hospitalized from the emergency department and underwent surgery. Results A total of 12682 patients were included in the study. In the operated group the median CRP level (23.1 [0.1-377.4] mg/dL) was the highest, the mean WBC number (13.8±6.2 K/µL) was the highest, the median lymphocyte percentage (12.8 [0.2-55.6] %) was the lowest, the median neutrophil number (9.9 [1.0-43.8] K/µL) was the highest, the mean platelet number (254.2±88.1 K/µL) was the highest, the median neutrophil/lymphocyte ratio (6.1 [0.5-425.2]) was the highest and the median platelet/lymphocyte ratio 143.9 [16.9-2019.4] was the highest. Conclusions Our large-scale study shows that hematological-inflammatory parameters, which are routinely studied in patients presenting with abdominal pain, can be used to distinguish patients who will be discharged from the emergency service and those who require hospitalization
