Using Alvarado practical score and rate of neutrophil to lymphocyte in diagnosis of acute appendicitis

ABSTRACT

The study was conducted on 150 patients (82 males, 68 females) with acute appendicitis these were undergone appendectomy at the Military Central Hospital 108 between January 1998 and December 1999. These patients were examined retrospectively using Alvarado Practical Score combined with rate of neutrophil to lymphocyte more than 3.5. Mean age of patients was 3719.86 years (ranged from 92 to 2 years). Time from disease onset to operation is 20.8814.54 hours. The Alvarado practical score was applied easily, simple and appropriate for health clinics without modern equipment. For patient group in this study, the Alvarado practical score provided the sensitivity of 96.2% and specificity of 57.1% in diagnosis of acute appendicitis. Rate of neutrophil to lymphocyte produced the sensitivity of 73.6% and specificity of 85.7%. There was significant gender difference in diagnosis of acute appendicitis. Male is sevenfold more likely to be diagnosed accurately than female.
