Area of Science:

  • Thoracic Surgery
  • Pulmonary Medicine
  • Surgical Techniques

Background:

  • Lung segmentectomy is a key procedure for small lung nodules.
  • Accurate identification of intersegmental borders is crucial for safe and effective segmentectomy.
  • Existing methods for intersegmental demarcation can be complex or less precise.

Purpose of the Study:

  • To evaluate a modified, simpler technique for distinguishing intersegmental borders during lung segmentectomy.
  • To assess the accuracy and safety of this novel demarcation method.

Main Methods:

  • Analysis of 539 patients undergoing anatomic segmentectomy for lung nodules (<2 cm).
  • Preoperative 3D CT bronchography and angiography for precise dissection guidance.
  • Modified inflation-deflation method for intersegmental demarcation under unilateral differential ventilation.

Main Results:

  • The modified inflation-deflation method showed high coincidence with the actual intersegmental border.
  • Dissection along the demarcated border using electrocautery or staples resulted in minimal air leak and bleeding.
  • The technique was found to be safe and effective.

Conclusions:

  • The modified inflation-deflation technique is a simple and effective method for intersegmental border demarcation in lung segmentectomy.
  • This approach offers a reliable alternative to previously described methods, enhancing surgical safety and precision.
