Follow-up was done by telephone or at an outpatient clinic. The deadline for follow-up was February 2022.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The operative time, the chest tube indwelling time, and the hospital stay duration were significantly shorter in the VATS group compared with the thoracotomy group. The intraoperative and postoperative complication rates in the VATS group were lower than that of the thoracotomy group (<jats:italic>P<\/jats:italic>\u2009&amp;lt;\u2009.05). In thoracoscopic surgery, the clinical symptoms during the course of the disease were significantly associated with bleeding loss increasing [odds ratio (OR)\u2009=\u20093.562; 95% confidence interval (CI) 1.180\u201310.753, <jats:italic>P<\/jats:italic>\u2009=\u2009.024] and operation time extension (OR\u2009=\u20095.697; 95% CI 1.529\u201321.221, <jats:italic>P<\/jats:italic>\u2009=\u2009.010). The relationship between lesions and superior vena cava or innominate vein from preoperative CT imaging was significantly associated with bleeding loss increasing (OR\u2009=\u20094.629; 95% CI 1.463\u201314.639, <jats:italic>P<\/jats:italic>\u2009=\u2009.009). A maximal lesion diameter greater than 7\u2005cm was significantly associated with increased risks of operation time extension (OR\u2009=\u20095.019; 95% CI 1.641\u201315.348, <jats:italic>P<\/jats:italic>\u2009=\u2009.005).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Compared with traditional thoracotomy surgery, VATS can be performed safely in selected patients with MMT.
