Abstract: Objective To explore the safety, efficacy and feasibility of 3D laparoscopic subtotal thyroidectomy via a breast
approach. Methods The clinical data of 30 patients undergoing 3D laparoscopic subtotal thyroidectomy via a breast approach
were analyzed in comparison with 30 patients receiving traditional laparoscopic subtotal thyroidectomy during the period
from September, 2013 to December, 2013. The operation time, blood loss, postoperative drainage, postoperative hospital stay,
and total hospitalization expenses were compared between the two groups. Results The operation time in the 3D group was
significantly shorter than that in the 2D group (45 ± 26.3 vs 62 ± 24.8 min, t=0.53, P<0.05). The intraoperative blood loss,
postoperative drainage, postoperative hospital stay and total hospitalization expenses did not show significant differences
between the two groups. Conclusions 3D laparoscopic subtotal thyroidectomy via a breast approach is safe and effective and
shortens the operation time, and can be used as a routine operation for subtotal thyroidectomy.
