Feasibility and Safety of Single-Port Video-Assisted Thoracic Surgery for Primary Lung Cancer

Abstract

Background: The feasibility of single-port video-assisted thoracic surgery (SPVATS) for primary lung cancer is not well u nderstood. In this study, we compared S P and multi-port ( MP) VATS f or t he s urgical treatment of patients with primary lung cancer. Methods: Surgical treatment was performed in 181 patients with primary lung cancer at Inje University Haeundae Paik Hospital between June 2012 and December 2015. A propensity- matched analysis was used to compare the postoperative outcomes and to evaluate the comparative feasibility a nd s afety of S PVATS and MPVATS. Results: There were 37 patients in the SPVATS group and 67 patients in the MPVATS group. Propensity matching produced 32 pairs. The operation time (210 minutes versus 200 minutes, p=0.11), volume of the estimated blood loss (170 mL versus 160 mL, p=0.19), duration of chest tube drainage (5 days versus 6 days, p=0.66), and length of hospital stay (9 days versus 10 days, p=0.89) were similar between the 2 groups. Conclusion: In our study, SPVATS for primary lung cancer was safe and feasible i n well selected p atients. A p rospective, randomized study with a large g roup a nd l ong-term follow-up is necessary to evaluate the clinical feasibility and the advantages of SPVATS for primary lung cancer.
