Objective: Appendicitis scoring systems have been developed as a diagnostic tool to improve the decision-making process in patients with suspected appendicitis.The aim of the study was to compare the results of the Alvarado, The Pediatric Appendicitis Score, modified Pediatric Appendicitis Score, Lintula, and Tzanakis scoring systems in childhood appendicitis. We also aimed to see whether our rates of correct diagnosis and negative appendectomy could change, if we had made decisions using the scoring systems.
Materials and Methods: The patients who underwent appendectomy because of suspected appendicitis between June 2019 and June 2020 were evaluated prospectively. The patients were divided into appendicitis and non-appendicitis groups according to histopathological findings. The obtained data were used to calculate the scores for the scoring systems and statistical analyses.
Results: In the study, 141 patients were included. The negative appendectomy rate was 14.8%. The lowest negative appendectomy rate (6.38%) was obtained with the Lintula scoring system. Tzanakis scoring system had the highest accuracy rate (85.1%) compared to the other scoring systems.
Conclusion: The present scoring systems may assist in establishing the diagnosis of appendicitis and reducing negative appendectomy rates. The Lintula scoring system has the lowest negative appendectomy rate due to its higher specificity compared to Alvarado, Pediatric Appendicitis Score, modified Pediatric Appendicitis Score, and Tzanakis scoring systems. Tzanakis scoring system has the highest accuracy rate in the diagnosis of appendicitis, and thus we believe that it may be used as an alternative scoring system for children.
