Background. The hybrid ultrasonic advanced bipolar device (HUB) that integrates ultrasonic energy and advanced bipolar energy was recently developed and applied to thyroid surgery. The purpose of this study was to compare the efficacy and safety of HUB and ultrasonic coagulating shears for open thyroidectomy. Methods. A total of 200 patients were enrolled from April to September 2017 in this prospective, randomized, multicenter study. Patients were randomly assigned to an ultrasonic group (n = 101) or a hybrid group (n = 99). Results. Operation times were similar in the 2 study groups, that is, 54.2 ± 25.2 minutes in the ultrasonic group and 50.2 ± 21.6 minutes in the hybrid group. Postoperative surgical results and morbidities were no different in the 2 groups. However, the total amount of bleeding was significantly less in the hybrid group (13.0 ± 17.7 mg vs 8.6 ± 11.5 mg; P = .042). Conclusions. Our study showed that there was no significant difference between the 2 groups in postoperative surgical results and morbidity. The total bleeding amount was significantly less in the hybrid group. The study shows that HUB is comparable to the ultrasonic coagulating shears in terms of efficacy and safety during thyroid surgery.
