OBJECTIVETo analyze the effect of three-dimensional (3D) laparoscopic total thyroidectomy combined with central lymph node dissection for thyroid cancer and its effect on the inflammatory response of the patients.

METHODSThe clinical data were analyzed in 90 patients with thyroid cancer undergoing radical thyroidectomy at our hospital between September, 2013 to April, 2016, including 30 receiving 3D laparoscopic surgeries, 30 with 2D laparoscopic surgeries and 30 with open surgeries. The surgical data, postoperative adverse reactions and the impact of the surgeries on the inflammatory responses of the patients were compared among the 3 groups.

RESULTSCompared with the open surgery and 2D laparoscopic surgery, 3D laparoscopic surgery was associated with lowered blood loss during the surgery and a lowered incidence of adverse reactions. The operation time in 3D group was significantly shorter than that in 2D group (P<0.05), but the total hospitalization expenses were similar between the two groups. The postoperative drainage volume did not differ significantly between the 3D group and the other two groups. The postoperative hospital stay, number of lymph nodes dissected, positivity rate of lymph nodes and the inflammatory response showed no significant differences among the 3 groups (P>0.05).

CONCLUSION3D laparoscopic total thyroidectomy combined with central lymph node dissection is safe and effective and reduces intraoperative blood loss and perioperative adverse reactions without significant influence on inflammatory response in patients with thyroid cancer.
