title: [Resources of intraoperative diagnosis of thyroid gland diseases].
abstract: The method of intraoperative laser autofluorescent spectroscopy (IOLAS) has been developed and introduced in clinical practice for improvement of intraoperative diagnosis of thyroid gland diseases. 112 patients (17 men, 95 women, mean age 46.5 +/- 3.8) with various thyroid diseases were examined. Benign diseases were revealed in 96 (85.7%) patients, thyroid cancer--in 16 (14.3%). All the patients were operated. Rapid histologic examination and IOLAS were performed in all the patients. Main spectral characteristics and criteria of differential diagnosis of benign and malignant thyroid diseases were determined. High diagnostic value of this method was demonstrated. Results of IOLAS were compared with USI, thin-needle aspiration biopsy, express histologic examination. Sensitivity of IOLAS in differential diagnosis of malignant thyroid diseases achieves 95.4%, specificity--97.6%. IOLAS permits to clarify the morphology of thyroid lesions and to choice optimal scope of surgery. In accordance to IOLAS the scope of planned surgery was expanded in 18.2% cases that permitted to avoid repeated operations after elective histologic examination. It is concluded that the method may be used for optimisation of intraoperative diagnosis of thyroid diseases.
