a Ports and instruments placement in right-side surgery. The operator always stands at the right side of the patient. Both of the operator’s arms are comfortably and ergonomically placed, b Ports in left-side surgery. Note the 10 mm posterior port placed anteriorly to the scapular tip (small arrow), which is different from the right-sided port placement (5 mm, posteriorly to the scapular tip). Sometimes the camera is inserted through this posterior port during subcarinal lymph node dissection, left paratracheal lymph node dissection, or lower lobar sleeve resection and bronchial anastomosis
