In this article it is aimed to investigate the efficiency of PAS and additional laboratory data in diagnosing appendicitis.Material and Methods: Between 1st January 2010 and 31st December 2010, patients admitted to our department that are followed up and treated with an initial diagnosis of acute abdomen were reviewed retrospectively. Patients which were operated and histopathological examination confirmed the diagnosis appendicitis is defined as 1st group, and the patients with negative exploration and the ones that are non-operated are defined as 2nd group. Groups are compared in terms of demographic data, hospitalization time, PAS and laboratory data. Results: A total of 562 patients (321 male, 241 female) with an initial diagnosis of acute abdomen are admitted to our department in the one-year period. There were 350 patients (224 acute, 126 complicated appendicitis) in the 1st group, and 212 patients (31 negative exploration, 181 follow-up) in the 2nd group. While the preoperative hospitalization time between the acute and complicated cases did not have significant difference (p>0.05), complicated cases had a long postoperative hospitalization time (p<0.001). PAS had significant difference between the acute, complicated and negative explorations (p<0.001). PAS was increased proportional to the severity of the appendicitis (p<0.001). White blood cell count, neutrophile count, neutrophile percentage, neutrophile/lymphocyte (N/L) ratio, and C-reactive protein (CRP) rates were significantly higher in the appendicitis group (p<0.001). Fever (in the 1st group 29.1%) and the migration of pain to right-lower quadrant (in the 1st group 6.2%) that are the PAS components had at least contribution to the scoring. Instead, the usage of N/L (81% higher in the 1st group) and CRP (76% higher in the 1st group) values increases the sensitivity of the score from 88.6% to 91.1% in diagnosing appendicitis. conclusion: Addition of the N/L ratio and CRP values may increase the diagnostic ability of the PAS which is composed of clinical and laboratory indications}, number={2}, publisher={T.C.
