Diagnostic value of basic laboratory parameters for simple and perforated acute appendicitis: An analysis of 3392 cases (neutrophil-to-lymphocyte ratio, platelet count, mean platelet volume, serum bilirubin)

Abstract

Presence of at least 1 of the following findings in a patient suspected of having acute appendicitis was significantly associated with a definite diagnosis: WCC >11.900 mm3, serum bilirubin >1.0 mg/dl, NLR >3.0. In patients with acute appendicitis, serum bilirubin >1.0 mg/dl or NLR >4.8 were significantly associated with the presence of perforation. While WCC is a significant parameter for diagnosis of acute appendicitis, no significant association with perforated appendicitis was found. PLT and MPV were not useful parameters when diagnosing acute appendicitis.
