Appendicitis in Children
What is appendicitis?
Appendicitis occurs when the appendix, an appendage (extension) of the colon, becomes inflamed (swollen) and infected. In many cases, an obstruction (blockage) within the appendix causes the infection, resulting in bacterial overgrowth. In 20 to 30 percent of children, the appendix ruptures and releases the infection into the abdominal cavity.
How common is appendicitis?
Appendicitis affects 80,000 children per year in the United States. It is most common in the second decade of life. Fifty percent of children will have a family history of appendicitis. Appendicitis is the most common cause for emergency abdominal surgery in childhood.
