Introduction and Epidemiology

Background

Acute appendicitis is a common and considered as emergency illness and thus immediate treatment needed. it has high morbidity and any delay of the diagnosis can be fatal. It is mildly hard to diagnose acute appendicitis since there is no single sign, clinical features, or diagnostic test that accurately can be used to confirm the diagnosis of acute appendicitis.

Epidemiology

United States:  7% of US population with strong association of family history with mortality rate of 0.2-0.8%

International:  mostly acute appendicitis is high in poor country in which their citizens consume less fibre diet. this because it is believed that high fibre-diet can reduce the feces viscosity, and decrease the incidence of bowel obstruction.
