INTRODUCTION: Appendicolith can be incidentally detected on abdominal computer tomography (CT) without any signs of appendicitis. However, it has also been found to be a risk factor for failure of nonoperative management in acute appendicitis. The present retrospective study aimed to evaluate whether appendicolith predicts complicated appendicitis in patients with any appendicitis.
METHODS: A retrospective chart review was conducted for patients undergoing appendectomy from January 2016 to December 2018. Appendicolith was considered to be present when it was described in a CT scan.
RESULTS: Of the 267 patients, appendicolith was found in 120 cases, while there were no in 147 cases in preoperative CT scans. In the case of complicated appendicitis (gangrenous or gangrenous perforated appendicitis), appendicolith was visible in CT scans in 57.7% of the patients. Of the patients with uncomplicated appendicitis, 38.3% had appendicolith in CT scan (p = 0.002). In univariate logistic regression analysis, based on the finding of the histological specimen, appendicolith was associated with complicated appendicitis (OR: 2.12; 95% CI: 1.28-3.51; p = 0.004). When adjusting for sex, age group (age ≤50 vs. >50 years), and duration of symptoms (≤24 vs. >24 h), the odds ratio was 3.52 (95% CI: 1.88-6.58; p < 0.001).
CONCLUSION: Our study found that appendicolith can be considered an independent risk factor for complicated appendicitis. Therefore, in the presence of appendicolith, surgical treatment should probably be preferred over nonsurgical treatment in acute appendicitis.
