The main feature of the uniportal VATS approach consists of targeting, through a caudocranial (sagittal) plane, any area of surgical interest inside the chest (see Figure ). Two advantages result from such a perspective: (1) the procedure allows for a similar approach as is used for open surgery and (2) the reacquisition of the depth of visualization lost with conventional three-port The latter is based on the Uniportal VATS seen as the fulcrum of the armamentarium of the modern thoracic surgeon. Caudocranial approach (., sagittal plane) for uniportal VATS. 206 Uniportal video-assisted thoracoscopic surgery (VATS) Schematic of the simultaneous insertion of the development of a transversal latero-lateral (or anteroposterior) plane, along which the operative instruments are deployed to address the target With the current 2-D technology, the surgical maneuvers impede in-depth visualization through a centrally located videothoracoscope because of the torsion angle created by the operative instruments (see Figure ).3,4 As a result, traditional three-port VATS demands an extent of hand–eye coordination to overcome the geometrical obstacle originating from this torsion angle (see Figure ).4 This hand–eye coordination represents an added difficulty, especially during hilar dissection during VATS lobectomy, and this has possibly undermined the more universal acceptance of the procedure, which is otherwise appealing. Conversely, in the .
