Lobectomy with high-position single-intercostal two-port video-assisted thoracoscope for non-small cell lung cancer is a safe and effective surgical procedure

Background: High-position single-intercostal two-port video-assisted thoracic surgery (VATS) technique has been used for thoracic diseases. It can effectively avoid postoperative chronic pain compared with the traditional three-port VATS. This study aimed to evaluate the safety and efficacy of high-position single-intercostal two-port video-assisted thoracoscopic lobectomy.

Methods: From June 2014 to December 2018, a total of 474 patients in our hospital with non-small cell lung cancer (NSCLC) underwent lobectomy with a high-position single-intercostal two-port video-assisted thoracoscope. A retrospective study of these patients was conducted, and follow-up was performed to analyze the patients' 3- and 5-year survival rates.

Results: Of the total number of patients, 27.6%, 41.4%, and 31% underwent surgery between the third, fourth, and fifth intercostals, respectively. During the operation, 31 patients were converted to open surgery or three-port thoracoscopic surgery. The average surgical time was 160.9±44.9 min, the average postoperative hospital stay was 5.6±3.4 days, the incidence of postoperative complications was 7.2%, and the average number of lymph nodes resected was 13.6±5.3. The 3-year overall survival (OS) rate of IA1, IA2, IA3, IB, IIA, IIB and IIIA was 99.0%, 98.6%, 96.3%, 91.2%, 85.7%, 66.7%, and 60.8%, respectively. Meanwhile, the 5-year OS rate of IA1, IA2, IA3, IB, and IIIA was 99.0%, 94.5%, 87.5%, 85.5%, and 43.3%, respectively.

Conclusions: Lobectomy with a high-position single-intercostal two-port video-assisted thoracoscope for NSCLC is a safe and effective surgical procedure.
