To explore the selection of laparoscopic techniques and the stress response during the radical resection of thyroid cancer.

126 patients with thyroid cancer treated in our hospital from March 2014 to February 2018 were selected, and they were randomly divided into three groups: group A, group B, and group C, with 42 cases in each group, and they were given 3D laparoscopic resection, 2D laparoscopic resection and open surgery respectively. Data processing application statistics software SPSS22.0 was completed. In this study, the incidence of postoperative complications was compared by chi-square test, and the related indexes of operation and the index of stress response were indicated by (±s). The comparison of the three samples was compared with the single factor analysis of variance; P<0.05 was statistically significant.

The operation time of group A was shorter than group B (P<0.05), which was longer than group C (P<0.05). The blood volume of group A was lower than that of group B and C (P<0.05), and the volume of drainage of group A was lower than that of group B (P<0.05). The incidence of postoperative complications in the three groups of A, B and C groups were 4.8%, 11.9% and 26.2% respectively. The difference was statistically significant (P<0.05). The incidence of complications in group A was lower than that of group C (P<0.05). The levels of BG, P and CRP in the three groups were higher than those before operation (all P<0.05), and the group A<group B< group C (P<0.05), the group A had the lowest stress response after operation.

3D laparoscopic surgery for thyroid cancer can significantly reduce the amount of intraoperative blood loss and complication rates, the safety is high. The stimulation to the body is less than 2D laparoscopic and open surgery. The effect is significant and it is worthy of popularization and application.
