Abstract

Background: The purpose of this study was to study the clinical symptoms, laboratory data, and the characteristics of computed tomography (CT) imaging of nonoperated perforated appendicitis for predicting the recurrence of appendicitis. Methods: Thirty-five patients with nonoperated perforated appendicitis were retrospectively reviewed for this study. During a median follow-up period of 1155 days, 7 patients had to receive an appendectomy owing to recurrent appendicitis. Accordingly, the patients were divided into 2 groups: the recurrence and the nonrecurrence group. The clinical characteristics between these 2 groups were compared. Results: Both of the 2 patients who had a past history of appendicitis suffered recurrent appendicitis (the recurrence versus the nonrecurrence group, P < .05). The only CT imaging relating to the recurrence of appendicitis is the presence of calcified appendicolith (the recurrence versus the nonrecurrence group, P < .001). Conclusions: It is most likely that appendicitis will recur if a calcified appendicolith on CT imaging or a past history of appendicitis is presented. Interval appendectomy may be reserved only for those patients who possess one of these risk factors of recurrent appendicitis.
