Comparative research of the Harmonic Focus? and Ligasure Small Jaw? in open thyroid surgery / 中国癌症杂志

ABSTRACT

Background and purpose:In recent years, energy-based instruments have been widely used in today’s open surgeries. Harmonic Focus? (HF) and Ligasure Small Jaw? (LSJ) are both custom-made for thyroid open surgery. This study aimed to explore the effcacy and safety of HF and LSJ in open thyroidectomy.Methods:The data from patients who undertook total thyroidectomy with central neck dissection by the same surgeon during last year in this hospital were reviewed. HF was used in 100 patients, and LSJ was used in 104 patients. The effectiveness was appraised by comparing operation time and postoperative volume of drainage on the ifrst postoperative day. The safety was appraised by comparing the incidence of postoperative complications.Results:The results of the effectivenessthe average duration of operation was (95.8±18.0) min for HF group, and (97.8±19.1) min for LSJ group, there was no statistical signiifcance (P=0.363). Postoperative volume of drainage on the ifrst postoperative day was (35.2±20.3) mL for HF group, and (36.3±23.8) mL for LSJ group, there was no statistical signiifcance (P=0.977). One patient (1.0%) had temporary vocal cord paralysis in HF and one had postoperative hematoma (1.0%) in LSJ group. Temporary hypo-parathyroidism was detected in 18 patients (18.0%) of HF group, and 16 patients (15.4%) of LSJ group. The decline of parathyroid hormone during the ifrst postoperative day was (12.3±12.8) pg/mL in HF group, and (13.9±13.4) pg/mL in LSJ group. The decline of serum calcium was (0.20±0.13) mg/dL in HF group, and (0.20±0.16) mg/dL in LSJ group. There were all no statistical signiifcances (P>0.05).Conclusion:Both HF and LSJ are safe and effective in open thy-roidectomy without similar operative complications.
