Computerized tomography, non-contrast enhanced CT, appendix, acute appendicitisAbstract
Background: Acute appendicitis is the most common acute abdominal condition requiring surgery. The diagnosis of acute appendicitis is usually based on clinical signs, symptoms and results of a simple laboratory examination. Computerized tomography (CT) is indicated for investigation in patients with atypical clinical manifestations of appendicitis. Routine contrast-enhanced computed tomography (CECT) increases cost and morbidity. However, many authors defend its use to assure a higher efficacy. A retrospective study was performed among 310 patients with suspected appendicitis but equivocal clinical manifestation and laboratory examination between January 2023 and December 2023 from medical records (PTL-HOS) and CT images from Picture Archiving and Communication System (PACS). CT diagnosis was made by: presence of an abnormal appendix, appendicoliths, periappendiceal fat stranding, periappendiceal abscess and absence of signs that may lead to other diagnosis. The findings were correlated with surgical histopathology which being the gold standard for confirmation of appendicitis.
Results: Non-contrast enhance CT in 108 patients had 97.1% accuracy, 94.7% sensitivity, 98.5% specificity, 97.3% positive predictive value and 97.0% negative predictive value.
Conclusions: Non-contrast enhanced CT presents a similar overall accuracy.
