Abstract
Purpose
Debate on the effect of in-hospital delay on the risk of perforation in appendicitis persists, and the results from previous studies are controversial. The aims of this study were to present the effect of in-hospital delay on the risk of perforation in appendicitis and to assess the utility of C-reactive protein (CRP) measurement in detecting the patients with complicated appendicitis.
Methods
Prospectively collected data of 389 adult patients who underwent surgery for acute appendicitis were analyzed in order to find the most accurate method for recognizing the pre-hospital perforations. The effect of in-hospital delay on the further risk of perforation in patients with not yet perforated acute appendicitis was then analyzed.
Results
Out of 389 patients with appendicitis, 91 patients (23.4 %) had complicated appendicitis, 23 with abscess, and 68 with free perforation. Admission CRP level of 99 mg/l or higher was 90.3 % specific for complicated appendicitis. In patients with admission CRP less than 99 mg/l, the incidence of perforation doubled from 9.5 to 18.9 % when the in-hospital delay increased from less than 6 h to more than 12 h.
Conclusions
Complicated appendicitis can be identified with a high CRP level on admission. Delaying surgery can increase the risk of perforation.
