Summary
The two-windows method offers a minimally invasive approach for lung cancer surgery. This technique facilitates effective mediastinal lymph node dissection, potentially becoming a new standard for early-stage lung cancer treatment.
Area of Science:
- Thoracic Surgery
- Minimally Invasive Procedures
- Surgical Oncology
Background:
- Refinement of minimally invasive thoracoscopic surgical procedures.
- Establishment of the novel two-windows surgical method.
Purpose of the Study:
- To evaluate the efficacy of the two-windows method for pulmonary lobectomies and mediastinal lymph node dissection in lung cancer patients.
- To establish a standard minimally invasive surgical approach for early-stage lung cancer.
Main Methods:
- The two-windows method involves two skin incisions (2-3 cm each) placed posteriorly and anteriorly in the fourth intercostal space.
- Pulmonary lobectomies with thoracoscopy and mediastinal lymph node dissection were performed on 100 consecutive Stage I lung cancer patients.
- The procedure was optimized for direct visualization and manipulation around the tracheal bifurcation.
Main Results:
- Mean operative time: 2 hours 46 minutes.
- Mean blood loss: 68.2 mL.
- Mean number of mediastinal lymph nodes dissected: 24.3.
- Achieved comparable mediastinal lymph node dissection extent to standard thoracotomy.
- The method allows conversion to a standard thoracotomy if necessary.
Conclusions:
- The two-windows method is a viable and effective minimally invasive technique for treating Stage I lung cancer.
- The procedure facilitates thorough mediastinal lymph node dissection.
- This method has the potential to become the standard surgical treatment for Stage I lung cancer.
