摘要
Abstract Objectives Finding a reliable preoperative predictor of complicated acute appendicitis (AA) has been a challenging diagnostic problem. The present study aimed to identify potential factors that may predict complicated AA in the pediatric emergency department (ED) based on routine, widely available laboratory tests on admission to the ED, including plasma sodium concentration. Methods We retrospectively reviewed clinical and laboratory data of pediatric patients with AA who underwent emergency surgery at our department between January 2020 and December 2022. The patients were divided into two groups: histopathologically proven complicated (n = 80), and non-complicated AA (n = 155). Results Complicated AA was associated with reduced plasma sodium and chloride concentrations (p < 0.001, both), decreased values of lymphocytes (p = 0.002), elevated C-reactive protein (CRP) (p < 0.001), elevated values of white blood cells (WBC) and neutrophils (p = 0.012 and 0.001, respectively). In binomial logistic regression, increased CRP, WBC, and decreased sodium levels were predictors of complicated AA. The area under the ROC curve was 0.825 (95% CI 0.764, 0.886). Conclusion We identified mild hyponatremia and elevated CRP and WBC values as potential markers for distinguishing complicated from uncomplicated pediatric AA with implications for treatment approach, either surgical in complicated or conservative in uncomplicated disease.
