[The Main Technical Points of Thoracoscopic Anatomical Lung Segment Resection]

Area of Science:

• Thoracic Surgery
• Pulmonary Medicine
• Surgical Oncology

Background:

• Thoracoscopic segmentectomy is complex due to anatomical variations in segmental bronchi and vessels.
• Preoperative imaging is crucial for planning and nodule localization in segmentectomy.
• Accurate identification of inter-segmental planes is vital for successful segmentectomy.

Purpose of the Study:

• To describe the technical challenges of thoracoscopic segmentectomy.
• To introduce and evaluate a novel
• Cone-shaped Segmentectomy
• technique for anatomical segmentectomy.

Main Methods:

• Utilizing preoperative 3D-CTBA for anatomical visualization and nodule localization.
• Employing dissection of segmental bronchi/vessels, preservation of inter-segmental veins, and inflation-deflation method.
• Implementing the
• Cone-shaped Segmentectomy
• principle for precise separation of pulmonary segments.

Main Results:

• The
• Cone-shaped Segmentectomy
• technique allows precise dissection of target bronchi and vessels.
• Anatomical separation of inter-segmental borders is achieved, enabling complete anatomical segmentectomy.
• The technique facilitates accurate nodule localization and safe surgical margins.

Conclusions:

• The
• Cone-shaped Segmentectomy
• technique offers a precise and anatomically guided approach to thoracoscopic segmentectomy.
• This method addresses the technical complexities of segmentectomy, potentially improving patient outcomes.
• Preoperative imaging combined with this technique enhances the safety and efficacy of lung segment resection.
