Reliability of Leukocytosis in Diagnosing Acute Appendicitis.

Acute appendicitis is a frequently encountered surgical disease. Detection is difficult even with imaging and blood investigations. Total leukocyte count is a promising investigation. Its role in the confirmation of acute appendicitis is investigated and analysed in the present study. MethodsPatients having acute appendicitis treated by surgical intervention (appendicectomy) were included in the study. The leukocyte count measured before surgery was compared with histopathology findings of the appendix. Parameters of diagnostic accuracy of leukocytosis were measured by standard formulae. ResultsThe sensitivity and specificity of leucocytosis were found to be 76 percent and 12.5 percent respectively. The positive predictive value and negative predictive value of leucocytosis was 65 percent and 20 percent respectively. Overall diagnostic accuracy was 56 percent. The results were compared with histopathology of acute appendicitis. ConclusionsLeukocytosis is a helpful investigation to support the diagnosis of acute appendicitis.
