Accuracy of Modified Alvarado Score, Eskelinen Score and Ohmann Score in Diagnosing Acute Appendicitis.

INTRODUCTION By processing the data of a large number of patients with abdominal pain, diagnostic scores whose implementation attempts to facilitate acute appendicitis diagnostics were developed. Modified Alvarado score, Ohmann score and Eskelinen score are used as assistance when setting the diagnosis and making a decision to undertake surgery. AIM To assess accuracy of Alvarado score, Ohmann score and Eskelinen score in diagnosing acute appendicitis and to establish connection of total score of these scoring systems with histopathological degree of appendicitis. SUBJECTS AND METHODS A cross-sectional study was conducted at the Department of Surgery of University Clinical Hospital Mostar. The study included 70 patients who underwent appendectomy and were scored before surgery. All tested persons were examined by experienced surgeon who took anamnesis, physical status and ordered laboratory diagnostic tests. Appendicitis was excluded or confirmed by means of histopathological diagnostics, and the degree of appendicitis was determined. RESULTS According to accuracy parameters (sensitivity, specificity, negative and positive predictive value), the score which was of highest value was Ohmann score, followed by Eskelinen score, while the lowest value was the one of modified Alvarado score. Total score in all three scoring systems follows the degree of appendicitis, but statistical significance was proven only for Ohmann and Eskelinen scores. CONCLUSION Ohmann and Eskelinen scores can be useful in diagnosing acute appendicitis, predicting the degree of appendicitis, as well as assistance when making decision to undertake an operative procedure. Modified Alvarado score in our subjects did not prove sufficient value. Diagnostics of acute appendicitis still must be led by contemporary algorithms in which diagnostic scoring is implemented.
