Characteristic of reparative processes after thyroid surgery by electric welding of biological tissues

Abstract

Aim. Determination of differences in reparative processes after using electric welding of biological tissues technology in thyroid surgery by Ultrasonography  examination of operated area in postsurgical period. Materials and methods. The electric welding apparatus — highfrequency surgical coagulators EK300-M1 and  EKVZ-300 «Patonmed» and our own developed adaptive bipolar coagulation instruments were used. Ultrasonography examination was performed in 20 and  60 days  after surgery, the results were evaluated by 4-point scale of soft tissue scarring. Results. The introducing the electric welding of biological tissues technology into  thyroid surgery allowed to reduce the operation time, the blood loss and significantly minimize the use of the threads. The state of the operated area was studied by  ultrasound after surgery. There were 212 patients selected, 96 of which were operated by electric welding of biological tissues, and 116 — without it using a thread- ligature hemostasis for this. We revealed that the degree of scarring was less in patients operated with electric welding of biological tissues, and this effect was more  evident in organ salvage surgery: hemithyroidectomy and resections of the thyroid gland.
