BackgroundAcute appendicitis is one of the most common causes of acute abdominal pain prompting emergency department (ED) visits. It is critical for the physicians to promptly and accurately diagnose acute appendicitis. The present study aimed to evaluate the diagnostic efficacy of Doppler ultrasonography (USG) in patients with acute appendicitis and compare this new method with other commonly used radio-diagnostic tools.MethodsAll patients who were diagnosed with acute appendicitis at the Kecioren Training and Research Hospital ED and later underwent appendectomy between October 2012 and April 2013 were included in the study. Approval from the ethics committee was obtained for this prospective study. The patients' demographic information, physical examination findings, vital signs, Alvarado scores, and laboratory and radiological exam results were recorded.ResultsA total of 60 patients were enrolled in the study. In 46 of the 60 patients, diagnosis of acute appendicitis was confirmed by histopathology results, whereas 14 patients, diagnoses was not confirmed by lab tests. Doppler USG could detect 43 of the 46 patients as true positives, and it detected 2 of the 14 patients with negative lab results as false positives. For diagnosis of acute appendicitis, sensitivity of appendicular Doppler USG was 93%, specificity was 85%, accuracy was 91%, positive likelihood ratio was 6.5, and negative likelihood ratio was 0.08.ConclusionDoppler imaging can offer a high level of diagnostic success in patients with acute appendicitis. Appendicular Doppler USG offers a rapid and easy application without the need to expose patients to contrast medium and is superior to both USG and computed tomography. Therefore, we recommend the use of appendicular Doppler imaging as the primary radiological exam in diagnosing acute appendicitis.
