Effectiveness of Ultrasonography and Computed Tomography in the Diagnosis of Acute Appendicitis

Abstract

Background: Acute appendicitis is the acute inflammation of the appendix vermiformis and is one of the leading emergency intra-abdominal surgeries. In the study; To investigate the effectiveness of preoperative USG and CT in the diagnosis of acute appendicitis. Materials and Methods: The records of 332 patients who underwent appendectomy between March 2018 and March 2023 were retrospectively examined. Gender, age, USG and CT reports and patho-logy results of the patients were recorded. Sensitivity, specificity, positive predictive value and negative predictive values of USG and CT in the diagnosis of acute appendicitis were calculated separately. Results: The pathology result was reported as acute appendicitis in 312 of the patients, and was evaluated as normal in 20 of them. The pathology result of 254 of 261 patients, whose CT results were evaluated as compatible with acute appendicitis, was reported as acute appendicitis. In 7 patients, it was found to be normal appendicitis. Of 28 patients whose CT results were incompatible with acute appendicitis, the pathology result was positive in 18 and negative in 10. Pathology results of 96 patients whose USG results were compatible with acute appendicitis; Acute appendicitis was found in 90 patients and normal appendix in 6 patients. Pathology results of 41 patients whose USG results were evaluated as negative; It was reported to be compatible with acute appendicitis in 36 cases and normal in 5 cases. Conclusions: In our study, both the sensitivity and specificity of CT were found to be superior to USG, consistent with the literature. Researching IT effectiveness; We think that prospective studies com-paring teleradiology reports and the reports of radiologists working in hospitals would be useful.
