Comparison of 980-nm/1470-nm Dual-Wavelength Fiber Laser Versus Ultrasonic Scalpel Device in Open Thyroidectomy.

Background

To investigate the application value of 980-nm/1470-nm dual-wavelength fiber laser in thyroidectomy.

Methods

The clinical data of 130 patients undergoing thyroid surgery from March 2017 to December 2018 were retrospectively analyzed. According to the use types of energy devices, the patients were divided into laser group and ultrasonic scalpel group, with 65 patients in each group. The baseline data, operation-related indicators, operation complications, postoperative pathological conditions, and follow-up results of the two groups were compared.

Results

The operations were successfully completed in both groups. The median operative time of total thyroidectomy (TT), lobectomy+central lymph node dissection (CLND), TT+CLND in the laser group were longer than that in the harmonic scalpel group, and the difference was statistically significant (p < 0.05). The incidence of parathyroid gland congestion in the laser group (10.3%) was lower than that in the harmonic scalpel group (19.2%), and the difference was statistically significant (p < 0.05). No significant differences were found in operative type, intraoperative blood loss, postoperative drainage volume, operative complications, postoperative hospital stay, and lymph node metastasis rate between the two groups (p > 0.05). No incidence was noted of recurrence, metastasis, or death in both groups.

Conclusions

The 980-nm/1470-nm dual-wavelength fiber laser had an efficacy in open thyroidectomy similar to that of the harmonic scalpel, was safe and feasible, and less damage to the parathyroid gland blood supply than a scalpel. It can be used as a new option for thyroid surgery.
