“…Наиболее часто тонкоигольную аспирационную биопсию (ТАБ) осуществляют с использованием одноразовых шприцев разной емкости (5, 10, 20 мл 3 ). В большинстве случаев реализация данного исследования производится по методике Free hand [3,9], выполнение которой подразумевает одновременное использование обеих рук в момент забора цитологического материала при условии выполнения процедуры одним специалистом. Это приводит к слепому забору цитологического материала, что может способствовать непроизвольному смещению иглы в сторону важных анатомических структур, а при наличии двух специалистов (врача ультразвуковой диагностики и врача, выполняющего процедуру) возможна неправильная визуализация иглы из-за отсутствия синхронности в работе специалистов.…”

Background: Due to its availability, high information content and harmlessness, ultrasound is an extremely effective method of differential diagnosis of thyroid pathology. Despite the sufficient arsenal of diagnostic methods, thyroid biopsy with cytological examination is the «gold» standard in diagnostic algorithms. Most often, fine — needle aspiration biopsy is carried out using disposable syringes of different capacities (5, 10, 20 ml3). The procedure is performed in most cases according to the «Free hand» method, this leads to several problems associated with the peculiarity of the study, primarily with the low vacuum created in the syringe and insufficient collection of cytological material, as well as insufficient practical experience for a novice specialist.Aim: Determination of the range of the possibility of using vacuum aspiration fine needle biopsy under the control of ultrasound navigation in patients with focal thyroid pathology.Materials and methods: On the basis of the Problem Research Laboratory «Diagnostic studies and minimally invasive technologies» of the Smolensk State Medical University, a device for vacuum fine — needle aspiration biopsy was developed. In the period 2019–2020, 780 vacuum fine — needle aspiration biopsy was performed under the control of ultrasound navigation in patients with thyroid nodules. The level of vacuum in the syringe during sampling of the material was — 0,5 bar (- 50 kPa).Results: A comparative analysis of the cytological results obtained with the help of vacuum fine — needle aspiration biopsy and the «Free hand» method shows a decrease in obtaining the category of Bethesda 1 by 3.3% and Bethesda 3 by 10.2%.Conclusion: This indicates the effectiveness and in formativeness of the use of vacuum fine — needle aspiration biopsy in patients with focal thyroid pathology in comparison with the standard «Free hand» method, as well as with vacuum fine — needle aspiration biopsy due to constant visual monitoring and the lack of movement of the syringe piston to create a discharge when taking cytological material, the probability of needle deviation from the biopsy zone is reduced, which increases the effectiveness of the study and facilitates the work of a novice specialist.

“…Несмотря на достаточный арсенал диагностических методов, позволяющий заподозрить узловые изменения ЩЖ биопсия с цитологическим исследованием является «золотым» стандартом в диагностических алгоритмах. Морфологическое исследование позволяет выявить и дифференцировать патологию ЩЖ на ранних стадиях, когда клинические проявления могут отсутствовать, а лабораторно -инструментальные результаты минимальны [5][6][7][8].…”

One of the main diagnostic methods used in diseases of the thyroid gland is ultrasound examination of the thyroid gland. Due to its availability and noninvasiveness, high information content, ultrasound is an extremely effective method of differential diagnosis of thyroid pathology. Despite the sufficient Arsenal of diagnostic methods that allows us to suspect nodal changes in the thyroid gland, a cytological biopsy is the “golden standard” in diagnostic algorithms. The use of ultrasound control methods for performing minimally invasive interventions significantly facilitates manipulation and reduces the risk of possible complications, but does not exclude the possibility of their occurrence. In connection with all the above, there is an idea to create a device that helps to facilitate the performance of a fine-needle aspiration biopsy to a specialist, reduce the risk of possible complications and increase the information content. In the Problem scientific research laboratory «Diagnostic studies and minimally invasive technologies” of the Smolensk state medical University developed a device to increase the efficiency and informational content of fine-needle aspiration biopsy under the control of ultrasound navigation in patients with nodular formations of the thyroid gland. 26 (9.5%) patients were performed fine-needle vacuum aspiration biopsy using the created device, thanks to which 18 (6.6%) patients were found to have adenomatous formation, changes in the type of subacute thyroiditis were found in 5 (1.8%) patients, and 3 (1.09%) cases of follicular neoplasia. In cases where a higher discharge is necessary for the collection of cytological material, and the developed device allows you to create conditions that increase the information content and facilitate the procedure, in addition, it is possible to perform the procedure by one specialist, which reduces the workload of several specialists in the Department dealing with minimally invasive interventions.

“…Дифференцировка узлов ЩЖ часто проводится не столько по наличию основных признаков злокачественности (раки), сколько по их отсутствию (доброкачественные образования) [3,4]. Однако хоро шо известно, что рак щитовидной железы (РЩЖ) имеет много "масок" (клинических, ультразвуковых, цитологических) и часто имитирует доброкачественную природу узла.…”

Оn the need to introduce the TI-RADS classification in Russia

et al. 2019

An active discussion of TI-RADS modifications (Thyroid Imaging Reporting And Diagnostic System) classification continues in the world professional medical community. This system of thyroid nodules stratification on the malignancy signs is intended primarily to select thyroid nodules for a fine needle aspiration biopsy. The classification should be uniform for all medical institutions of our country, easy to use and understandable by various medical specialists. This article presents a modification of TI-RADS prepared for discussion in the professional communities of Russia. Some “major” ultrasound features of malignancy (with specificity >95%) and additional or “minor” features (with specificity >90%) of thyroid nodules are pointed out to emphasise the need of fine needle biopsy. After comparison of diagnostic parameters of proposed TI-RADS and European TIRADS (EU-TIRADS), both systems showed comparable specificity of 93%, while sensitivity of proposed TI-RADS was slightly higher than for EU-TIRADS, with 94.2% and 91.0%, respectively. This discrepancy may be related to “minor” features of malignancy which were taken into consideration.
