11. Is VATS superior to OPEN?
Common answer = “Yes”
Equivalent oncologic outcomes1,3
Similar chest tube drainage, LOS, pain2
Similar pneumonia, air leak,
arrhythmia, mortality3

12. Transition from OPEN to VATS
How far have we come?
Limited adoption of VATS lobectomy:
STS data = 28-35%1-2 of cases
ESTS data = 11%3 of cases
Why?

13. Single-port or Uniportal VATS
Early publications:
2000: Migliore M
2004: Rocco G
2011: Gonzalez-Rivas D
Popular topic:
Last 10 years: 1000 cases reported
Last 6 months: >400 cases reported
14. Only 3 retrospective comparisons:
n≈200 cases
Early outcomes are similar
