Abstract

Background: Although using energy devices during open thyroidectomy might shorten the procedure time compared with the conventional technique, its effect on procedure-related complications remains unclear and controversial. In an era of cost containment, we aimed to compare the rate of procedure-related complications (particularly vocal cord palsy and hypoparathyroidism) between patients who underwent thyroidectomy using reusable ultrasonic shears and those who did not.

Methods: Of 508 eligible patients, 237 (46.7%) underwent thyroidectomy using the SonoSurg (reusable ultrasonic shears; SonoSurg group) and 271 (53.3%) underwent thyroidectomy using the conventional technique (suture ligation and clips; conventional technique group). The reusable shears were autoclaved at the end of each procedure and replaced after every 20 cases. To evaluate the effect of the ultrasonic shears on procedure-related complications, the patient characteristics and outcomes were compared between the 2 groups.

Results: In the SonoSurg group, the total operating time (60 min versus 105 min, P < 0.001) and temporary (12.4% versus 25.5%, P = 0.009) and permanent hypoparathyroidism (1.9% versus 9.8%, P = 0.003) rates were significantly less than those in the conventional technique group. The permanent vocal cord palsy rate was similar (P = 0.262). On multivariate analysis, using the reusable shears (odds ratio 0.163; 95% confidence interval 0.047-0.570; P = 0.005) and parathyroid autotransplantation of at least 1 gland (odds ratio 0.370; 95% confidence interval 0.146-0.943; P = 0.037) were the 2 independent variables for permanent hypoparathyroidism after completion/total thyroidectomy.

Conclusions: Using the reusable shears during open thyroidectomy was significantly associated with a shortened operating time and lower permanent hypoparathyroidism rate, although the vocal cord palsy rate remained similar.
