Introduction Although non-operative management of acute appendicitis may be appropriate in selected cases, surgery remains the gold standard treatment. Prioritization of patients at risk of developing complicated appendicitis is essential for improving outcomes. The aim of this study was to assess the predictive value and clinical utility of the Appendistat (APS) scoring system as a triaging tool to prioritize patients with a high risk of developing complicated appendicitis. Methods This was a chart review, cross-sectional observational diagnostic study, with a single-gate retrospective design, including 592 patients who underwent appendicectomy. Based on final histological diagnosis, patients were categorized as normal, acute uncomplicated appendicitis (AUA), or acute complicated appendicitis (ACA). The predictive value matrix of the APS score for identifying patients with a histological diagnosis of complicated appendicitis was calculated.
