Early Stage Non-small-cell Lung Cancer (Stage 1-2) Clinical Trial
Official title:
Ergonomical Assessment of Three-Dimensional Versus Two-Dimensional Thoracoscopic Lobectomy for Lung Cancer
Video-assisted thoracic surgery (VATS) pulmonary lobectomy is currently widely employed as
the first treatment option for surgical management of early stage (stage I-II)
non-small-cell-lung-cancer (NSCLC).
Thanks to recent technological advances in high definition display systems, three dimensional
VATS (3D) has been developed in an attempt of overcoming some optical limits of two
dimensional (2D) VATS.
In this single center randomized trial our aim is to comparatively assess ergonomics of 3D
versus 2D VATS lobectomy for early stage NSCLC.
Video-assisted thoracic surgery (VATS) is widely employed for pulmonary lobectomy in early
stage non-small-cell-lung-cancer (NSCLC). Indeed, VATS is thought to represent an optimal
minimally invasive surgical option which is deemed superior to conventional thoracotomy since
it enables smaller incisions with no rib spreading thus minimizing both postoperative pain
and hospital stay.
For over than three decades, several thoracic surgeons adopted VATS for anatomical lung
resection using two-dimensional (2D) display systems. However, a 2D image lacks depth of
perception which may negatively affect surgical manoeuvring.
Three dimensional (3D) display systems for VATS can offer superior magnified vision of the
surgical field and better perception of depth during surgical manoeuvring potentially
shortening learning curve, which may thus overcome some optical limitations of 2D systems.
In this single center randomized trial our aim is to comparatively assess ergonomics of 3D
versus 2D VATS lobectomy for early stage (stage I-II) NSCLC. For this purpose we compared
three ergonomical domains: exposure, instrumentation and maneuvering with the aid of a
scoring scale entailing analysis of 5 main technical steps: vein, artery bronchus, lymph node
and fissure score.
The evaluation process of the five surgical steps was carried out by 4 thoracic surgeons who
individually scored all recorded operations.
