Summary

This study shows a new bipolar radiofrequency ablation (BRFA) device is safe and effective for thyroid hemostasis during thyroidectomy, with minimal complications. Its precise energy delivery protects nerves like the recurrent laryngeal nerve (RLN).

Area of Science:

Surgical Technology
Minimally Invasive Surgery
Nanotechnology in Medicine

Background:

Thyroidectomy commonly involves significant bleeding.
Effective hemostasis is crucial for patient safety and outcomes.
Novel energy devices are being developed to improve surgical safety.

Purpose of the Study:

To evaluate a novel bipolar radiofrequency ablation (BRFA) device utilizing nanotechnology.
To assess the device's efficacy in controlling bleeding during thyroidectomy.
To determine the safety profile of the BRFA device in this surgical context.

Main Methods:

A single institution performed 58 thyroidectomies using the BRFA device (EnSeal) for hemostasis.
Clinicopathologic data and complications were systematically recorded.

Outcomes were compared with existing literature on other energy devices.

Main Results:

The BRFA device was used in 58 thyroidectomies with a mean operating time of 81 minutes.
Average blood loss was 46 mL, with 90% of patients discharged within 23 hours.
No hemorrhages occurred; one recurrent laryngeal nerve (RLN) injury and one transient hypocalcemia case were reported.

Conclusions:

The BRFA device demonstrates initial safety and effectiveness for thyroid hemostasis.
Minimal thermal spread makes the device potentially advantageous for structures near the operative field, such as the RLN.
Further research is warranted to confirm these findings in larger patient cohorts.
