[Diverticular disease of the appendix]

The incidence of appendiceal diverticulosis in pathologic specimens is 0.004-2.1%. Diverticular disease of the appendix is classified as congenital (true) or acquired (false). The clinical presentation differs from that of acute appendicitis. The average age is older, the pain is often intermittent, and while localized in the right lower abdominal quadrant, is of longer duration. No further treatment besides appendectomy is needed. Since a high rate of perforations, peritonitis and lower gastrointestinal bleeding have been reported as complications, it is recommended that in those with an incidental finding of diverticula of the appendix during surgery, that appendectomy be performed. It is not recommended to perform prophylactic appendectomy when diverticula of the appendix are found on barium enema.
