Diagnosis of Acute Appendicitis Using Clinical Alvarado Scoring System and Computed Tomography (CT) Criteria in Patients Attending Gujarat Adani Institute of Medical Science - A Retrospective Study

The aim was to evaluate the clinical Alvarado scoring system and computed tomography (CT) criteria for the diagnosis of acute appendicitis. The study was carried out retrospectively in patients who were referred to the Institute between March 2014 and January 2015. One hundred seventeen patients with acute abdominal pain who underwent abdominal CT were enrolled in this retrospective study. Patient demographics, clinical Alvarado scoring, CT images, and pathologic results of the patients were evaluated. Thirty nine of the 53 patients who were operated on had pathologically proven acute appendicitis. CT criteria of appendiceal diameter, presence of periappendiceal inflammation, fluid, appendicoliths, and white blood cell count (WBC) were significantly correlated with the inflammation of the appendix. The optimal cut-off value of the appendiceal diameter was 6.5 mm. The correlation between appendiceal diameter and WBC was 80% ( =0.01
