Laboratory Markers in the Prediction of Acute Perforated Appendicitis in Children

Objective. 'is study aimed to explore the laboratory markers associated with perforation in children with acute appendicitis. Methods. 'is retrospective study reviewed 1895 children (3–18 years old) with confirmed acute appendicitis from 2007 to 2017. Clinical (demographic characteristics, symptoms, and signs) and laboratory data (white blood cell count, C-reactive protein (CRP), procalcitonin, D-lactate, platelet count, bilirubin, aspartate aminotransferase, and alanine aminotransferase) were collected and compared between perforated and nonperforated groups. 'e logistic regression analysis was performed to identify independent risk factors. Results. Of all patients, 613 children were perforated. Children with perforation had significantly longer duration of symptoms, higher white blood cell count, CRP level, and neutrophils percentage, and lower serum sodium level. Elevated white blood cell count with CRP level and elevated neutrophils percentage with CRP level were found to be associated with risk of perforation. Conclusions. White blood cell count with C-reactive protein and neutrophils percentage with CRP are important markers in distinguishing perforated appendicitis from nonperforated appendicitis in pediatric subjects.
