BACKGROUND Several scoring systems have been developed to aid clinicians in diagnosing acute appendicitis. Tzanakis scoring system is one of the modern scoring systems which uses clinical, USG, and laboratory markers. Alvarado score is one of the commonly used scoring systems. But the accuracy of diagnosing acute appendicitis has been low. This study compares the ability of Tzanakis scoring system with that of Alvarado score in predicting acute appendicitis. METHODS A prospective non-randomized study was conducted among 100 patients who were diagnosed to have acute appendicitis admitted in the Department of General Surgery, PESIMSR- KUPPAM, between December 2017 to August 2019. After complete clinical, radiological, and laboratory workup, Alvarado, and Tzanakis score was compiled, and patients underwent appendicectomy based on the clinical acumen of the operating surgeon. Histopathology results were analysed postoperatively with preoperative scores. RESULTS Out of 100 patients, the sensitivity, specificity, positive predictive value, and negative predictive value of Tzanakis score was 52.7 %, 92.31 %, 97.78 %, and 21.82 % respectively. CONCLUSIONS The Tzanakis scoring system at a cut-off score of >8 is an effective scoring system than the Alvarado score for the diagnosis of acute appendicitis.
