Abstract Objectives Single-port thoracoscopic lobectomy is a new therapeutic technique for patients with lung cancer; however, insufficient data are available regarding its clinical outcomes. We therefore compared the clinical outcomes of single-port and two-port thoracoscopic lobectomies for lung cancer. Methods We retrospectively analyzed and compared the data of 204 and 368 patients with lung cancer who underwent single-port or two-port thoracoscopic lobectomy, respectively, between October 2014 and October 2017 at our institution. Patients in both groups underwent 1:1 propensity score matching, and 400 patients (200 patients in each group) were included. Perioperative clinical indicators were analyzed, including operation time, lymph node dissection stations and numbers, incidence of postoperative complications, and pain scores at 24 h, 72 h, and 1 week after surgery. Results No perioperative deaths occurred in either group. The operation time, intraoperative blood loss, chest drainage duration, duration of postoperative hospital stay, lymph node dissection station and number, rate of conversion to open surgery, number of ruptured intraoperative pulmonary vessel, and incidence of postoperative complications were not significantly different between the groups (all P > 0.05). However, analysis of the 24-h (P = 0.005), 72-h (P = 0.011), and 1-week (P = 0.034) visual analog scale score after surgery revealed that the postoperative pain levels were significantly lower in the single-port than in the two-port group. Conclusions Single-port and two-port thoracoscopic lobectomies had similar perioperative outcomes, although the postoperative pain was lower after single-port than two-port thoracoscopic lobectomy. Hence, we concluded that single-port thoracoscopic lobectomy is an effective, minimally invasive, and promising surgical procedure.

Introduction Lung cancer is a serious malignant disease, with the highest mortality rate of all the malignant diseases [1]. Resection (most commonly lobectomy) is one of the main treatment modalities for lung cancer. Thoracoscopic lobectomy for lung cancer was first performed in the 1990s [2]; furthermore, it is widely favored by thoracic surgeons and patients, as it involves minimal invasiveness, rapid recovery, and * Cheng‑guang Hu [email protected] 1
