Comparison of surgical outcomes and complications between the Harmonic FOCUS and conventional surgery for open...

The aim of the present study was to evaluate the potential advantages of the ultrasonic scalpel compared with the conventional technique in thyroid surgery. Patients with resectable thyroid cancer and Basedow's disease were assigned to ultrasonic scalpel or conventional technique (knot-tying and electrocoagulation). The present study used the Harmonic FOCUS^® (HF) as an ultrasonic scalpel. Between February 2013 and May 2016, 45 patients were enrolled into the study. Duration of the surgery was significantly decreased in the HF group compared with the conventional surgery (CS) group (median 142 vs. 151 min; P=0.0406). Intraoperative blood loss and total volume of drainage fluid were significantly decreased in the HF group compared with the CS group (median 40 vs. 125 ml; P=0.0054, and median 120 vs. 175.5 ml; P=0.0490). Duration of drain placement and length of hospitalization stay were similar in the two groups. Furthermore, the overall incidence of postoperative complications did not differ between the two groups. Overall, the present study suggests that open thyroidectomy using the HF is safe and effective and not associated with any increase in complications.
