New hemostatic technologies (NT) in thyroid surgery showed a shorter operation time with the Harmonic Scalpel (HS). However, both HS and Ligasure (LI) were associated with higher morbidity compared to conventional techniques (CT).

Area of Science:

Surgical Innovation
Thyroid Surgery
Hemostasis

Background:

New hemostatic technologies (NT) are increasingly used in thyroid surgery.
Their effectiveness in reducing operating time and complications is under investigation.

Purpose of the Study:

To compare the efficacy of three hemostatic techniques in thyroidectomy.
Specifically, conventional technique (CT), Ligasure vessel sealing system (LI), and Harmonic Scalpel (HS).

Main Methods:

A prospective randomized study involving 150 patients undergoing total thyroidectomy.
Patients were assigned to CT, LI, or HS groups.
Demographics and outcomes were recorded.

Main Results:

Harmonic Scalpel (HS) significantly reduced operation time (p < 0.001).

Morbidity was higher in new hemostatic technology (NT) groups (HS and LI) compared to conventional technique (CT) (p = 0.0002).

NT patients exhibited significantly lower postoperative calcemia (p < 0.05).

Conclusions:

The primary advantage of new hemostatic technologies (NT) in thyroid surgery is a reduced operation time, particularly with the Harmonic Scalpel (HS).
Higher morbidity rates were observed with both HS and LI compared to conventional techniques.
