Overview

Appendicular abscess is one of the rarest entity that presents with abdominal pain. It occurs in around 2-7% of patients with appendicitis. Younger people, in the age group of 10-19, have a higher chance of developing appendicular abscess. Males are more likely than females to develop appendicular abscess. Caucasians are more likely to develop complication of appendicitis than non-Caucasians.

Epidemiology and Demographics

Prevalance

The lifetime risk of appendicitis is 8.6 % for males and 6.7 % for female of which only 2-7% develops abscess.[1]

Incidence

Annual incidence of appendicitis in united states is 9.38 per 100,000 persons.[2]

Age

It occurs most often between the ages of 10 and 30.[1]

Gender

Males are more commonly affected with appendicular abscess than females. The male to female ratio is approximately 1.4 to 1.[1]

Race

  • Appendicitis usually affects individuals of the white race.Non white individuals are less likely to develop Appendicitis.[1]
  • Appendicitis rates were 1.5 times higher for whites than for nonwhites, highest (15.4 per 10,000 population per year) in the west north central region, and 11.3% higher in the summer than in the winter months.
