To compare conventional open surgery and 2D and 3D assisted laparoscopic neck dissection for thyroid cancer.

The clinical data of 120 patients undergoing radical thyroidectomy from October 2015 to December 2017 were retrospectively analyzed. According to the surgical approach, they were divided into open group, 2D group, and 3D group, each 40 cases. The SPSS 21.0 statistical software package was used to analyze. The intraoperative and postoperative data and VAS scores were expressed as mean±standard deviation (±s), and compared with t test. Satisfaction rate of treatment and postoperative adverse reactions were compared by χ². P<0.05 indicated that the difference was statistically significant.

The operation time was longer in the 2D and 3D groups than in the traditional open group. The blood loss in the 3D laparoscopic group and the drainage volume within 24 hours after the operation were lower than those in the 2D group and the traditional group (P<0.05). There was no significant difference in the number of lymph node dissected and postoperative hospital stay and total discharge time among the three groups (P>0.05). The incidence of adverse reactions in the 3D group was significantly lower than that in the 2D abdominal group and the traditional group7.5% vs. 15% and 32.5%. The postoperative pain assessment at 24h and degree of satisfaction in 2D, 3D laparoscopic group were significantly better than those in open group (P<0.05).

The clinical application of 3D assisted laparoscopic neck dissection for thyroid cancer is safe and reliable, and is worthy of further promotion.
