Thoracoscopic precision excision technique for small lung lesions using radiofrequency identification marking

Area of Science:

• Thoracic Surgery
• Medical Imaging
• Oncology

Background:

• Multi-detector computed tomography (CT) increases incidental small lung nodule detection.
• Accurate diagnosis and treatment of these nodules are critical for potentially curative outcomes.
• Current minimally invasive techniques like stapler-based wedge resection have limitations, including potential sacrifice of healthy lung tissue.

Purpose of the Study:

• To present a novel wireless excision precision technique for small lung nodules.
• To address limitations of current thoracoscopic resection methods.
• To enable accurate nodule removal in a minimally invasive setting.

Main Methods:

• Development of a wireless excision technique using cone-beam CT-guided electromagnetic navigation bronchoscopy.
• Implementation in a hybrid operating room setting.
• Utilizing a radiofrequency identification microchip for tumor removal without intraoperative fluoroscopy or lung palpation.

Main Results:

• Successful demonstration of a wireless technique for precise small lung nodule excision.
• Avoidance of intraoperative fluoroscopy and lung palpation during thoracoscopic surgery.
• Potential to overcome limitations of stapler-based resections, preserving more pulmonary parenchyma.

Conclusions:

• The developed wireless excision technique offers a precise and minimally invasive approach for small lung nodules.
• This innovative method enhances safety and efficacy in thoracoscopic surgery.
• It represents a significant advancement in the management of incidentally detected lung lesions.
