Background: Surgical intervention is important for acute appendicitis. Perforated appendicitis leads to more complications and is more difficult to manage. Studies differentiating ruptured from nonruptured appendicitis are controversial. Aim: Early identification of perforated appendicitis is important for first-line medical practitioners. Our study aimed to provide more indicators to evaluate the risk of perforation before surgery. Methods: This retrospective study included 116 patients who underwent an appendectomy at the Tri-Service General Hospital between 2014 and 2018 with pathological diagnosis. Based on the surgical records, the patients were classified into two groups: simple (nonperforation) and complicated (perforation). Results: The patients (68 boys, 48 girls) were all under 18 years of age. Simple appendicitis was diagnosed in 87 patients and perforated appendicitis in 29 patients. Analysis revealed significant differences in blood C-reactive protein (CRP) levels between the two groups. The highest Youden's index was at a CRP level of 1.755 mg/dL. Positive findings were obtained for suppurative change as well as chylous ascites. Conclusion: Elevated CRP level was found to be a useful biomarker in predicting perforated appendicitis, excluding other general factors in pediatric patients. Suppurative change and chylous ascites could serve as indicators for the possibility of perforation during surgery.
