Comparative analysis between a bipolar vessel sealing and cutting device and the tie and suture technique in thyroidectomy: A randomized clinical trial.

Background: Advanced bipolar and ultrasonic devices have shown significant reduction in the surgical time of thyroid operations. This randomized, controlled trial assessed if operative time and other relevant outcomes are different for thyroidectomies performed either with a second-generation advanced bipolar device or traditional tie and suture technique.

Methods: Forty-one patients were randomized into 2 groups (advanced bipolar device and traditional tie and suture).

A randomized, prospective, parallel group study comparing the Harmonic Scalpel to electrocautery in thyroidectomy.

Background: Exhaustive hemostasis is essential to successful thyroidectomy. Electrocoagulation to control bleeding has the potential risk of injuring the surrounding structures from lateral dispersion of heat. The Harmonic Scalpel (HS) cuts and coagulates simultaneously using mechanical vibration rather than high temperatures.
