Purpose: The use of three-dimensional (3D) thoracoscope provides improved depth perception and accuracy in video-assisted thoracoscopic surgery (VATS). This study aimed to compare the surgical outcomes between two-dimensional (2D) and 3D VATS lobectomy for stage I lung cancer.
Methods: From January 2013 to May 2018, 354 patients underwent VATS lobectomy and mediastinal lymph node dissection for clinical stage I lung cancer. The 3D VATS system was introduced in July 2016 in our center. A total of 182 patients underwent 2D VATS lobectomy from January 2013 to June 2016, and 172 patients underwent 3D VATS lobectomy from July 2016 to May 2018.
Results: The thoracotomy conversion rate was lower (1.2% vs. 6.4%, P= 0.011) in the 3D VATS group than in the 2D VATS group. Operation time (mean: 119.0 minutes vs. 151.4 minutes, P< 0.001), operative blood loss (median: 100 mL vs. 150 mL, P< 0.001), and length of hospital stay after surgery (median: 5 days vs. 6 days, P< 0.001) were significantly lower in the 3D VATS group than in the 2D VATS group. A higher number of lymph nodes was resected in 3D VATS (mean: 15.9 vs. 13.8, P= 0.006). No significant difference was observed between 3D and 2D VATS in terms of operative complications (Clavien-Dindo classification grade ≥ 1; 14.7% vs. 14.6%, P= 0.322). None of the patients died postoperatively.
Conclusion: Our retrospective data showed that the 3D thoracoscope had better surgical outcomes than 2D thoracoscope for VATS lobectomy in patients with clinical stage I lung cancer.
