Surgeon-performed thyroid ultrasound-proving utility and credibility in selecting patients for fine needle aspiration according to the American thyroid association guidelines. A retrospective study of 500 patients.

DESIGN: Case series with chart review. SETTING: Single academic centre. PARTICIPANTS: The data of all patients who underwent surgeon-performed ultrasound (SUS) between 7/2009 and 9/2012 were retrospectively reviewed. MAIN OUTCOME MEASURES: A correlation between sonographic features and a non-benign cytology\malignant pathology. RESULTS: Four hundred ninety-eight nodules were included. Solid texture, irregular margins, hypo-echogenicity and intranodular vascularity were significantly associated with malignancy when benign to non-benign cytology was compared, and when compared to malignant pathology. Lack of suspicious features was significantly associated with benign lesions, with a negative predictive value of 94%. Except for taller than wider shape, malignancy odds ratio was significantly higher for known suspicious features, reaching 4.81 for irregular borders (CI 2.42-9.55, P < .001). CONCLUSIONS: SUS has proven to be a reliable and consistent tool to assess the thyroid nodule risk stratification. Surgeons should recognise the potential of this tool and its implementation.
