BackgroundSince the development of the uniportal video-assisted thoracoscopic surgery (VATS) technique, the use of uniportal VATS has become increasingly popular for the surgical resection of non-small cell lung cancer (NSCLC). The objective of this study is to introduce a novel modularly designed surgical pattern for uniportal VATS for lung cancer resection and to investigate the safety, feasibility, and efficacy of this novel method.Materials And MethodsThe clinical data of NSCLC patients who underwent a curative uniportal VATS lobectomy between March 2015 and April 2016, including via the modular pattern (MP) and the conventional pattern (CP), were retrospectively collected and analyzed. Perioperative and postoperative parameters, including the operation duration, estimated intraoperative blood loss, rate of conversion to thoracotomy, lymph node dissection number, and postoperative complications, were compared between the two groups.ResultsA total of 321 patients were identified, among whom 221 underwent MP uniportal VATS lobectomy and 100 were treated via CP uniportal VATS lobectomy. Patients in the MP group experienced a shorter operation duration (135.58 ± 47.16 minutes versus 148.86 ± 42.53 minutes, P = .017) and less estimated intraoperative blood loss (75.20 ± 37.99 mL versus 89.50 ± 41.11 mL, P = .003) than patients in the CP group. No significant difference was observed in the intraoperative conversion rate (2.7% versus 5.0%, P = .477), total number of lymph nodes dissected (24.67 ± 7.73 versus 25.34 ± 7.62, P = .471), postoperative drainage duration (4.86 ± 1.96 days versus 4.78 ± 2.10 days, P = .755), length of stay (9.60 ± 2.93 days versus 9.97 ± 2.80 days, P = .286), or incidence of postoperative complications between the two groups. No postoperative deaths occurred.ConclusionsMP uniportal VATS lobectomy combined with mediastinal lymphadenectomy appears to be a safe and feasible technique for the treatment of NSCLC. The use of this technique can reduce the operation duration and intraoperative blood loss.
