Abstract
AIM: The aim of the study was to compare the accuracy of common clinical findings, laboratory tests and diagnostic score (DS) in diagnosis of clinically confirmed acute appendicitis (AA) in children. PATIENTS AND METHODS: A cohort of 188 children under the age of 15 years presenting with acute abdominal pain (AAP) were included in the study. The clinical history (n=21), signs (n=14) and tests (n=3) were recorded in each child. RESULTS: The significant independent diagnostic predictors (disclosed by multivariate logistic regression model) were used to construct the DS formulas for AA diagnosis. These formulas were tested at six different cut-off levels to establish the most optimal diagnostic performance for clinically confirmed AA. In the receiver operating characteristic curve (ROC) comparison test, there was a statistically significant difference (p=0.0055) in the area under curve (AUC) values between i) clinical history and symptoms (AUC=0.594), and ii) signs and laboratory tests (AUC=0.734), whereas both were significantly inferior (p=0.0001) to the AUC value of the DS (AUC=0.952). CONCLUSION: In diagnosis of clinically confirmed AA in children, the DS formula is superior to both the clinical history/symptoms and signs/lab tests, justifying the use of DS as an integral part of the diagnostic algorithm of AA in all children presenting with AAP.
