Comparsion of the clinical application between Da Vinci robot and open operation in thyroid benign tumor with diameter greater than 5 cm / 国际外科学杂志

ABSTRACT

Objective:To evaluate the feasibility and safety of robotic thyroidectomy for treatment of thyroid benign tumor with diameter larger than 5cm.Methods:The clinical data of 36 patients (in the robot group) who received Da Vinci robot thyroid benign tumor surgery in the thyroid breast Surgery Department of the 960th Hospital of the PLA (Former Jinan Military General Hospital of PLA) from Jan. 2014 to Jun. 2019 were retrospectively analyzed, and compared with 48 patients (in the open group) who received open surgery in the same period.The operative time, intraoperative blood loss, length of hospital stay, postoperative drainage volume, postoperative parathyroid hormone, cosmetic effect, incidence of surgical complications and postoperative recurrence rate of the two groups were observed. Statistical software SPSS16.0 was used for statistical analysis of the data.Results:Both groups successfully completed the operation. Compared with the open group, the operation time ( t=11.232, P<0.001) and postoperative drainage volume ( t=2.892, P=0.003) of the robot group were more than those of the open group, and the aesthetic effect was better ( t=3.291, P=0.024). Intraoperative blood loss ( t=1.575 , P=0.118), hospital stay ( t=-1.784, P=0.091), postoperative PTH ( t=1.892, P=0.086), incidence of surgical complications ( χ2=3.291, P=0.610), visual analogue score of postoperative pain ( t=-2.431, P=0.081) and postoperative recurrence rate were not significantly different ( P>0.05). No recurrence occurred during follow-up. Conclusion:For patients with a selective benign thyroid tumor with a diameter of 5-8 cm, the bilateral axillo-breast and transaxillary approach for thyroid surgery by Da Vinci robot are safe, effective and have better cosmetic results.
