A COMPARATIVE STUDY OF TZANAKIS SCORE VS ALVARADO SCORE IN THE DIAGNOSIS OF ACUTE APPEDICITIS

Background: Acute appendicitis is the most common cause of sudden abdominal pain requiring surgery. Prolong duration of symptoms before the surgical intervention increases the risk of morbidity and mortality due to perforation. There have been several scoring systems to help the decision making process to reach diagnosis of acute appendicitis. ALVARADO and modified ALVARADO are the two most commonly used system worldwide. This study is being done to assess the accuracy of the TZANAKIS SCORING SYSTEM and ALVARADO SCORING SYSTEM in the diagnosis of acute appendicitis and reduce the rate of negative appendicectomy. Methodology: This was a hospital based prospective observational study conducted on patients admitted in the Department of General Surgery, Silchar Medical college and Hospital. This study was based on the analysis of 100 patients diagnosed to have acute appendicitis and underwent emergency open appendectomy from March 1st ,2020 – August 31st 2020. Aims and objectives: The aim of the present study is to assess the compare the accuracy of TAZANAKIS Scoring system and ALVARDO scoring system in the diagnosis of acute appendicitis. Results: The sensitivity, specificity, positive predictive value and negative predictive value of Tzanakis score was 83.72, 78.57, 96.0 and 44.0 respectively and of Alvarado score was 65.11, 35.71, 86.1 and 14.28 respectively. Negative appendicectomy was 14%. Conclusion: Tzanakis scoring system is an effective scoring system to establish the accurate diagnosis of acute appendicitis and helps in reducing negative appendicectomy rate.
