complete the resection; B: U-VATS instruments that are long and double hinged; C: the wound size for a U-VATS left upper lobectomy.
U-VATS: uniportal video assisted thoracoscopic surgery
Figure 2. Suggested uniportal video assisted thoracoscopic surgery learning pyramid for adaptation in training
during lymph node dissection. It was a successful surgery that took us 200 min to complete. Subsequent
lobectomies were performed without the assistant port. Left lower lobectomy was chosen as our first case
[1]
to perform because it is easier compared to other lobes . In 17 cases (10%), we used either an extra port
or converted to a mini-thoracotomy due to bleeding, to facilitate retraction or dissection, introduction of
