Diverticulosis of the vermiform appendix in patients with cystic fibrosis.

This paper presents a study of diverticulosis of the vermiform appendix in patients with cystic fibrosis. The records of two hospitals were reviewed. A total of 39 autopsy specimens and 18 surgical specimens were obtained. Diverticulosis of the appendix was found in 14 per cent (eight of 57) of all appendices. Two of these cases also showed diverticulitis. These results stand in contrast to the incidence of diverticulosis of the appendix in the general population, which has been measured at 1 to 2 per cent in various reviews.
