A Comparative Analysis of Hypocalcemia Incidence in Patients Undergoing Thyroidectomy: Ligasure vs Conventional Ligation of Vessels by Knot Tying

Ligasure is a bipolar vascular sealing system utilized to achieve effective control of bleeding and create a bloodless surgical environment. It operates by utilizing an electrical current within the frequency range of 2-4 MHz It induces denaturation of collagen and elastin within the vessels and surrounding tissues. The localized tissue temperatures typically range between 60-100°C, facilitating the fusion of collagen and elastin in the vessel walls. This fusion process creates a durable sealed zone without any carbonization and enables hemostasis in vessels with diameters of up to 7 mm.

Conventional methods of vessel ligation, which involve the use of ties and suture ligatures, have long been employed in most medical centers. While these techniques effectively control bleeding from vessels, they are time-consuming and carry the risk of harming adjacent structures like the recurrent and superior laryngeal nerves.
