Prospective Observational Study Evaluating Tzanakis Scoring System in the Diagnosis of Acute Appendicitis

Abstract

Background : Appendicitis is the most common abdominal emergency worldwide with lifetime risk of acute appendicitis 
is 8.6% and 6.7% for men and women respectively. The classical symptomatology only occurs in 50-60% of cases, with 
accuracy of clinical diagnosis of acute appendicitis being 70-87%. Approximately 20% to 33% of patients with suspected 
acute appendicitis have atypical findings making clinical diagnosis difficult. Diagnostic errors are common resulting in 
median incidence of perforation of about 20% and negative appendicectomy from 2% to 30%
