Navigating lung nodules for resection using a new mapping technique

What this trial studies

This clinical trial investigates a novel technique for localizing small pulmonary nodules using a method called watershed analysis, which allows for wedge resection without cutting blood vessels. The approach aims to reduce the need for CT-guided positioning, thereby saving costs and time in the operating room. By minimizing damage to lung tissue, the technique preserves pulmonary function and enables quicker patient recovery, with an average discharge time of three days post-operation. The study focuses on patients with early-stage non-small cell lung cancer (NSCLC) and aims to improve surgical outcomes.

Inclusion Criteria:

1. \<1cm CTR≤0.75; \<1.5cm CTR≤0.5; \<2cm CTR≤0.25 Lung nodules
2. The tumor center is located in the peripheral 2/3 area of the lung field
3. Preoperative analysis and planning of watershed by 3D reconstruction
4. Clinically assessed as cT1aN0M0 stage IA1/cT1bN0M0 stage IA2 (eighth edition), clinically resectable

Exclusion Criteria:

1. No surgical video, no postoperative gross specimen and related distance measurement records
2. The incision edge does not exceed the target nodule diameter from the nodule edge
3. The resection range exceeds 50% of the preoperative planning
4. Postoperative pathological staging non-pT1aN0M0 IA1 stage/pT1bN0M0 IA2 stage (eighth edition)
5. Any situation where the investigator feels the need for extended resection
6. Patients with chronic diseases (such as COPD, pulmonary fibrosis, silicosis) that can cause loss of lung function in patients at risk of progression or potential progression
