Three-port single-intercostal versus multiple-intercostal thoracoscopic lobectomy for the treatment of lung cancer: a propensity-matched analysis

Abstract

Background

In this retrospective study, we aimed to demonstrated that three-port single-intercostal (SIC) thoracoscopic lobectomy is an effective choice for lung cancer by comparing the perioperative outcomes of patients with non-small-cell lung cancer treated with three-port SIC and conventional multiple-intercostal (MIC) thoracoscopic lobectomy.

Methods

From January 2013 to January 2018, 642 non-small-cell lung cancer patients underwent thoracoscopic lobectomy via a three-port SIC or MIC technique. Propensity-matched analysis incorporating preoperative clinical variables was used to compare the perioperative outcomes between the two groups.

Results

The first 20 patients were excluded to account for the learning curve effect in the SIC group. Propensity matching yielded 186 patients in each group. A small percentage of patients had major morbidity, including 4.8% in the SIC group and 6.5% in the MIC group; there was no significant difference between the two groups. Although the total number of lymph nodes harvested (25.3 vs. 23.8, p = 0.160) and stations removed (6.5 vs. 6.7, p = 0.368) were similar between the two groups, more subcarinal lymph nodes were removed (6.9 vs. 5.2, p < 0.001) in the SIC group than in the MIC group. Furthermore, other perioperative outcomes in the SIC group were not fewer than those in the MIC group.

Conclusions

Both techniques are acceptable for the treatment of non-small-cell lung cancer. Three-port SIC VATS lobectomy can provide an alternative procedure in thoracoscopic surgery.
