title: Incidence of acute appendicitis confirmed by histopathologic diagnosis.
abstract: The annual incidence of acute appendicitis by gender, age, and race in Sedgwick County, Kansas was lower than values reported in most other communities. However, the trends of peak incidence during the second decade, male predominance among all races, and the highest incidence in Caucasians also were noted in the current study. The rates of perforation and gangrenous appendicitis were significantly higher in the elderly. No association was noted between the presence of fecalith and acute appendicitis or perforation. A better understanding of the etiology of acute appendicitis may explain the trends and differences in the incidence of acute appendicitis observed.
