Abstract
Appendicitis is generally a more serious disease in the elderly than in the young. In the former, perforation is seen commonly leading to the belief that the appendix perforates more readily and rapidly in the elderly. A competing view is that the appendix perforates relatively more frequently in the elderly than in the young. To distinguish between these two views we analyzed 126 cases of acute appendicitis stratified by age group. The time between onset of symptoms and perforation was calculated with a novel method that utilized the biological concept of T1/2 for perforation. Our findings suggest that the rate of perforation in the elderly is not significantly different from that in the young but the frequency of perforation is higher in the elderly. We concluded that appendicitis carries a graver prognosis in the elderly because the frequency of appendiceal perforation is higher in the elderly.
