Our distance-based method in the left upper lobectomy. The distance between multiple intercostal spaces and the resection target vessel candidates for stapler port place is measured by VINCENT. In this case, the sixth intercostal space (VD = 144.4 mm) was selected as the anterior stapler port place, and the tenth intercostal space (VD = 144.0 mm) was selected as the posterior stapler port place. VD: Virtual distance between the resection target vessel and stapler port place. Red circle: Assistant port place. Blue circle: Candidates for the anterior stapler port place. Yellow circle: Candidates for the posterior stapler port place. Green: Seventh rib
