Table 3. Institutional preference in RLN LN dissection using robot

En bloc semi-skeletonization is preferred
Half-circumference dissection (especially in left RLN LN dissection)
Keep the RLN LN attached to mediastinal structure
From lateral to medial direction
Energy device should be used keeping a distance of 5 mm or more from RLN
Identify inferior thyroid artery in both sides

RLN: Recurrent laryngeal nerve; LN: lymph node.

Figure 3. Port placement for the abdominal (A) and thoracic (B) procedures. The labeled numbers represent the robotic arm number.
Robotic staplers are inserted in arm no. 2 during abdominal procedures and in arm no.3 during thoracic procedures. A 12-mm port is
necessary for the robotic stapler arm. An assistant surgeon can share the glove port with the robot, and an additional assistant port is
not necessary. This figure is adapted from Park et al. J Thorac Dis. 2016;8:2853-61 [24] (https://doi.org/10.21037%2Fjtd.2016.10.39)
