IQQA-3D imaging interpretation and analysis system-guided single-port video-assisted thoracic surgery for anatomical sub-segmentectomy (LS1+2a+b)
Gradual improvements in health awareness and expanded physical examinations have resulted in more frequent discovery of pulmonary nodules, especially those of ground-glass opacity. In turn, diagnosis of early lung cancer is increasingly common. Surgeons have found that these early lung cancers may be safely removed via segmentectomy or sub-segmentectomy instead of lobectomy. However, the hilum structure of lung segments is complicated, and the many variations increase the challenge of performing segmental or subsegmental resection.
