Comparison Between the Tzanakis Scoring System and Yash Scoring System in the Diagnosis of Acute Appendicitis
Acute appendicitis is amongst the most encountered emergencies seen in casualties requiring intervention. The incidence of negative laparotomy is 15% to 25% and is associated with notable morbidity. Scoring systems are useful and logical for distinguishing acute appendicitis from non-specific abdominal pain. Presently many scoring systems exist that aids in the diagnosis of acute appendicitis but still fail to decrease the rates of wrong diagnosis and the negative appendicectomy rate. This

This comparative study has been undertaken to evaluate and compare the efficacy of the Tzanakis scoring system with the relatively newer Yash scoring system which has been found more effective for the Indian population in diagnosing acute appendicitis. Aim: To compare the efficacy of the Yash scoring system with the Tzanakis scoring system in diagnosing acute appendicitis. Method and Material: A prospective comparison of the Tzanakis scoring system and Yash scoring system was done on 50 patients. The decision of an appendicectomy was taken by the consultant surgeon. The outcomes of the Tzanakis scoring system and Yash scoring system in terms of sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were calculated and compared. Results: The Yash scoring system had sensitivity, specificity, PPV, NPV, and DA of 94.28%, 93.33%, 97.05%, 87.50%, and 94% respectively. The Tzanakis scoring system had sensitivity, specificity, PPV, NPV, and DA of 71.42%, 66.67%, 83.33%, 50%, and 70% respectively. Conclusion: The Yash scoring system was significantly better than the Tzanakis scoring system in diagnosing acute appendicitis.
