Less number of ports means less invasiveness—a Siren’s song?

Singe port video-assisted thoracic surgery (VATS) has become a hot issue in recent years. Although no strong evidence has been gained to support its superiority comparing to conventional multi-port VATS, many talented surgeons have proved its safety and oncological efficacy in various thoracic procedures including lung cancer surgery (1-7). The video presented in this issue of JOVS by Dr. Han and his colleagues (8) is another good example. Using a 2-cm single incision, the authors successfully completed a left upper lingual-sparing segmentectomy for a 1.7-cm ground glass nodule, which turned out to be an early stage adenocarcinoma with acinar and lepidic subtypes.
