This study investigated the safety and efficacy of glasses-free three-dimensional (3D) thoracoscopic surgery in minimally invasive esophagectomy for esophageal cancer. The results showed that compared with two-dimensional (2D) thoracoscopic surgery, glasses-free 3D thoracoscopic surgery had a shorter operation time, more lymph node dissection, and no significant difference in other clinical outcomes. Therefore, glasses-free 3D thoracoscopic surgery is considered a safe and effective surgical procedure for esophageal cancer.
Objective: To investigate the safety and efficacy of glasses-free three-dimensional (3D) thoracoscopic surgery in minimally invasive esophagectomy (MIE). Methods: The clinical data of 98 patients, including 81 men and 17 women aged 45-77 years, with esophageal squamous cell carcinoma who underwent minimally invasive thoracoscopic esophagectomy from January 2017 to December 2019 [3 years, with clinical follow-up time: 1 year similar to 4 years (2017.01-2020.12)] were retrospectively analyzed. Patients were divided into two groups according to different surgical methods including a glasses-free 3D thoracoscopic group (G-3D group: 38 patients) and a two-dimesional (2D) thoracoscopic group (2D group: 60 patients). The clinical outcome of the two groups were compared. Results: The operation time of the thoracoscopic part in the G-3D group was significantly shorter than that in the 2D group (P<0.05). The total number of lymph node dissection in the G-3D group was more than that in the 2D group (P<0.05). The thoracic indwelling time, postoperative hospital stay, severe pulmonary infection, arrhythmia, anastomotic leakage, chylothorax, and recurrent laryngeal nerve injury were not significantly different between the two groups (P>0.05). There was also no significant difference between the two groups on the progression-free survival (P>0.05). Conclusion: Glasses-free 3D thoracoscopic surgery for esophageal cancer is a safe and effective surgical procedure. Compared with 2D thoracoscopic MIE, glasses-free 3D thoracoscopic MIE for esophageal cancer has higher safety, more lymph node dissection, and higher operation efficiency through the optimized surgical operations. We believe that glasses-free 3D thoracoscopy for MIE is worthy of clinical promotion.
