Area of Science:

• Thoracic Surgery
• Minimally Invasive Procedures
• Pulmonary Function Analysis

Background:

• Uniportal video-assisted thoracic surgery (UVATS) presents technical challenges, particularly for anatomical segmentectomies like S9+10.
• Surgical resection extent impacts pulmonary function reduction.
• Comparing UVATS S9+10 segmentectomy with traditional basal segmentectomy is crucial for understanding functional preservation.

Purpose of the Study:

• To compare the efficiency of UVATS S9+10 segmentectomy versus video-assisted thoracic surgery (VATS) basal segmentectomy in preserving pulmonary function.
• To evaluate the safety and feasibility of UVATS S9+10 segmentectomy for early-stage non-small cell lung cancer.

Main Methods:

• Matched cohort study comparing UVATS S9+10 segmentectomy with VATS basal segmentectomy.
• Pulmonary function tests (PFTs) conducted preoperatively and at 3 and 6 months postoperatively.
• Statistical analysis of operative details, complications, and PFTs.

Main Results:

• No significant differences in blood loss, chest tube duration, ICU, or hospital stay between groups.
• No major postoperative complications or surgical mortality observed.
• UVATS S9+10 segmentectomy group demonstrated significantly better preserved pulmonary function (FVC, FEV1, FEV1%, DLCO) at 1 and 3 months postoperatively.

Conclusions:

• UVATS anatomic S9+10 segmentectomy is a safe and feasible technique.
• This approach offers superior pulmonary functional preservation compared to VATS basal segmentectomy.
• UVATS S9+10 segmentectomy is recommended for early-stage non-small cell lung cancer.
