Background : Acute appendicitis is the most frequent surgical emergency encountered worldwide. Diagnostic errors are common resulting in median incidence of perforation 20% and negative appendicectomy 2% to 30%.This study was conducted to compare the efficacy of Alvarado scoring and Tzanaki scoring in diagnosing acute appendicitisand to reduce the negative appendicectomy rate. Methodology : Prospective observational nonrandomized study conducted at Victoria hospital Bangalore which included 50 clinically diagnosed cases of acute appendicitis who underwent emergency open appendicectomy from Jan 2016 to May 2016.Final diagnosis was based on histological findings given by the pathologist. Results : The sensitivity, specificity, positive predictive value and negative predictive value of Tzanakis score was 79.62%,83.3%,97.72% and 31.25% respectively and of Alvarado score was 61.9%,50.0%,86.6% and 15% respectively. Negative appendicectomy in Tzanakis scoring was 12% and in Alvarado scoring was 16%. Conclusion : Tzanakis score is an effective modality to establish the accurate diagnosis of acute appendicitis and helps in reducing negative appendicectomy rate.Downloads
