Diagnostic Value of Platelet/Lymphocyte Ratio in the Diagnosis of Acute Appendicitis and its Relationship with Age

Aim: Acute appendicitis (AA) is one of the most common emergency surgical pathologies. The tests used in the differential diagnosis of these patients need to be quick, easy to access and cheap. Discussions continue about the value of laboratory tests in the diagnosis of AA. In this study, we aimed to determine the diagnostic value of platelet/lymphocyte ratio (PLR) in the diagnosis of AA and to determine its diagnostic value in different age groups. Method: Patients who underwent appendectomy after a preliminary diagnosis of AA between January 2015 and January 2020 were enrolled. Patients were divided into two groups, according to the postoperative pathology finding: group 1 (negative appendectomy) and group 2 (AA). In addition, groups were divided into subgroups based on age: 18-39 years, 40-59 years and 60 years and older. Platelet and lymphocyte counts and PLR were compared between groups and subgroups. In diagnostic accuracy evaluation ROC curve analysis was used; p
