A comparative study between harmonic scalpel hemostasis and conventional hemostasis in total thyroidectomy

Waleed Yusif El Sherpiny


Background: Thyroidectomy is the most commonly performed procedure in endocrine surgery. Since the thyroid gland is highly vascular, therefore, rapid and absolute hemostasis is extremely required. Conventional thyroidectomy is commonly used with acceptable outcomes, however, it is time‑consuming and resulted in significant intraoperative blood loss with the possible risk of postoperative hemorrhage, injury to parathyroid glands and laryngeal nerves. The advent of focus harmonic devices was encouraging for improving safety, effectiveness, and reduction of operative time, especially in thyroid surgery. Aim of this study: The purpose of this study was to analyze the effectiveness and surgical outcomes of using ultrasonic harmonic scalpel for thyroid surgery compared to conventional techniques.

Methods: This was a prospective, randomized study in which 60 patients with various types of goiters presented for thyroidectomy. The patients were divided into two comparable groups. Group A (30 patients) included patients who had focus harmonic thyroidectomy and Group B (30 patients) included patients who underwent conventional thyroidectomy.

Results: Focus harmonic thyroidectomy showed a significant reduction in operative time, intraoperative blood loss, volume of postoperative fluid drainage and meantime for hospital stay compared with conventional thyroidectomy. There were no significant differences in the incidence of postoperative hypocalcemia, seroma, hematoma, wound infection and laryngeal nerve injury between both groups.

Conclusions: Focus harmonic thyroidectomy was a safe, effective, faster, and appealing alternative to conventional technique since it reduced the operative time, intraoperative blood loss, postoperative drainage and hospital stay with comparable postoperative complications.
