Resumen
To reduce bleeding-related morbidity in th yroid surgery, new techniques and devices for controlling bleeding have been introduced in addition to traditional hemostasis. Innovative technological tools based on mechanical hemostasis systems, conventional mono- and bipolar electrosurgery systems, and radiofrequency and ultrasound systems can be variably associated with topical hemostatic agents and surgical sealants to improve hemostasis and avoid intra- and post-operative bleeding. The aim of the study was to describe the ultrasound (US) appearance of topical hemostatics in patients who were undergoing thyroidectomy. In particular, the study focused on the ultrasound appearance of a hemostatic swab, which in cases of incomplete resorption, can simulate disease recurrence (in oncological patients) or native gland residue. The study evaluated the possible advantages and disadvantages of the application of these agents to thyroid surgery, in particular those based on oxidized and regenerated cellulose and fibrin glue. The preliminary data reported in this study show that the effectiveness of hemostatic fibrin glue in preventing bleeding is comparable to oxidized regenerated cellulose swab; however, unlike the swab, the fibrin glue does not show any detectable residues at the US examination.
