Thyroidectomy with energy-based devices: Surgical outcomes and complications-comparison between Harmonic Focus, LigaSure Small Jaw and Thunderbeat Open Fine Jaw

Background: Being the thyroid gland a highly vascularized organ, achieving a meticulous hemostasis is essential to avoid serious complications. Currently, energy-based devices are widely used in thyroid surgery. The aim of this study was to compare Harmonic Focus (HF), LigaSure Small Jaw (LSJ) and Thunderbeat Open Fine Jaw (TB) in terms of surgical outcomes and complications. Methods: Patients undergoing thyroidectomy in our Unit between January 2012 and June 2018 were retrospectively analyzed. According to the type of energy-device used, patients were divided into three groups: Group A (HF), Group B (LSJ) and Group C (TB). Results: A total of 1,165 patients were included in this study: 1,012 in Group A, 96 in Group B and 57 in Group C. Demographic data and histopathological findings were comparable between the three groups. About the postoperative stay and complications, no statistically significant difference was found. The mean operative time was 89.41±20.60 minutes in Group A, 85.57±15.91 minutes in Group B and 78.07±17.67 minutes in Group C (P<0.01). However, the post-hoc test for all pairwise comparisons showed a statistically significant difference only between Group A and Group C. Conclusions: HF, LSJ and TB have proved to be safe and effective. The postoperative stay and complications were comparable between the three groups. Considering the limits of our investigation, further studies are needed to investigate the effect of TB on operative times.
