Tzanakis Scoring System in Acute Appendicitis Concern to Indian Population

Abstract

Background: 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 study has been undertaken
to evaluate the efficacy of the Tzanakis scoring system for the Indian population in diagnosing acute
appendicitis.
Method and Material: A prospective study to evaluate Tzanakis scoring system on 50 patients. The decision
of an appendicectomy was taken by the consultant surgeon. The outcomes of the Tzanakis scoring system in
terms of sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy
were calculated.
Results: The Tzanakis scoring system had sensitivity, specificity, PPV, NPV, and DA of 71.42%, 66.67%,
83.33%, 50%, and 70% respectively.
Conclusion: Tzanakis scoring system in diagnosing acute appendicitis has a lower value in Indian
populations
