[Comparative assessment of diagnostic methods in adenomas of the thyroid gland]

The authors carried out comparative assessment of sensitivity and specificity of ultrasonic examination with color dopper mapping (USE with CDM), thin-needle aspiration biopsy--TAB (palpation- and US-assisted), express histologic examination--(EHE), intraoperative laser autofluorescent spectroscopy (IOLAS) with retrospective assessment by results of elective histologic examination in adenomas of thyroid gland (TG). Medical histories of 135 patients hospitalized with adenomas of TG of follicular cells were analyzed. Based on comparison of USE with CDM and morphologic analysis of TG adenomas three types of specific echographic symptomcomplexes were recognized. USE with CDM in combination with US-assisted TAB was the most effective diagnostic complex before operation. Comparative analysis of results of these methods with express histologic examination showed equal efficacy, that permitted to reject routene EHE. For the first time IOLAS was used as "optic instant-biopsy" for selection of optimum scope of surgery when "follicular neoplasia" was suspected. Combined use of USE with CDM and TAB before operation as well as IOLAS enabled correct diagnosis of the nature of TG lesion, it morphologic type, and based on these data adegnatechoice.
