[The use of scintigraphy and fine needle aspiration biopsy (FNAB) in thyroid surgery and review of literature]

Abstract

Our aim is to know the usefulness of gammagraphy and FNAB (fine-needle aspiration biopsy) in thyroid surgery done in our ENT-Department during 12 years lapse. In this period of time are considered the outcomes of 461 thyroid gammagraphies and 469 FNAB for diagnostic comparison with the final anatomopathological (AP) issues. We emphasize the 42.3% of cold nodules most of which (21.5%) were thyroid carcinomas (80.95% papillary Ca; 14.28% follicular Ca and the remainder medullary Ca). Between 319 folliculary proliferations according of FNAB only 17 were malignant tumours and when the aspiration puncture informed about positive malignant etiology (51 cases), 5 cases final diagnosis were benign pathology and the other 2 the pathology was of malignancy, but different to that of the initial diagnosis. We considerer that the sensibility of this test is about 86.28% in our series. Finally, our results are compared with those of other publications.
