title: Progress of acute appendicitis: a study in children.
abstract: The results of six simple investigations are compared with the duration of the disease in 100 children with acute appendicitis. The results indicate that during the first day on which the appendix becomes inflamed the local defence mechanisms of the appendix are impaired sufficiently to allow invasion by the bacterial organisms in its lumen. This initially inflamed and subsequently infected appendix may develop in the manner indicated. Local and/or generalized complications may follow, i.e. acute appendicitis in its successive stages of development, which may be regarded as (a) inflamed, (b) infected and (c) complicated, and these changes take place at intervals of 1 day. Bacterial and faeoliths are present in the lumen of the appendix, whether inflamed or not, and it is suggested that they complicate the disease rather than being responsible for causing it.
