The Informativeness Improving of Fine Needle Aspiration Biopsy under Ultrasound Navigation in Surgical Endocrinology

Purpose : Determination of the effectiveness using a vacuum fine-needle aspiration biopsy compared to biopsy. Material and methods An original experimental sample has been developed for performing Also in course study, an improvement device was carried out, associated with peculiarity high pressure (over –0.5 bar), consisting throwing cytological material from needle directly into lumen syringe, its distribution along walls piston impregnation separating tissue membrane. From January November 2022, 118 were performed modified technique. Results During biopsy, it possible achieve absence uninformative (Bethesda 1) receipt 4.2 % (n = 5) amount atypia indeterminate value, which indicates this method. Conclusions 1. When stage taking is facilitated, creation discharge filling needle, feature contributes fewer movements area decrease production blood elements aspirate. 2. The use does not affect excessive traumatization thyroid parenchyma 3. ability select level depending on data multiparametric ultrasound examination, allows you individualize procedure. 4. modification form isolation syringe reduces loss increases
