    Appendicitis: Causes and incidence
    (Professional Guide to Diseases (Eighth Edition))

    Appendicitis probably results from an obstruction of the appendiceal lumen caused by a fecal mass, stricture, barium ingestion, or viral infection. This obstruction sets off an inflammatory process that can lead to infection, thrombosis, necrosis, and perforation. If the appendix ruptures or perforates, the infected contents spill into the abdominal cavity, causing peritonitis, the most common and most perilous complication of appendicitis.

    Appendicitis occurs more commonly in men than in women, with a peak incidence in the late teens and early 20s. About 250,000 cases are reported annually. It’s a common cause of surgical emergency in children, with 4 appendectomies per 1,000 admissions for appendicitis annually in the United States.

    • Peak incidence in teens and young adults, ages 15–25 years (boys 10–14, girls 15–19)
    • Affects 250,000 people per year in the US; 1:500 people each year worldwide

    About prevalence and incidence statistics:

    The term 'prevalence' of Acute Appendicitis usually refers to the estimated population of people who are managing Acute Appendicitis at any given time. The term 'incidence' of Acute Appendicitis refers to the annual diagnosis rate, or the number of new cases of Acute Appendicitis diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
