Summary

Radical sublobar resection is a viable option for early-stage lung cancer. A novel technique using selective jet ventilation improves visualization during video-assisted thoracic surgery (VATS) segmentectomy for small lung tumors.

Area of Science:

  • Thoracic Surgery
  • Surgical Oncology
  • Pulmonology

Context:

  • Sublobar resection, including segmentectomy and wedge resection, is increasingly considered for early-stage lung cancer (cT1N0, ≤2 cm).
  • Segmentectomy, an anatomic parenchyma-sparing procedure, is valuable for small lung carcinomas.
  • Minimally invasive approaches are preferred for thoracic procedures.

Purpose:

  • To present a technique for improved identification of the intersegmental border during segmentectomy.
  • To describe a hybrid video-assisted thoracic surgery (VATS) segmentectomy using selective jet ventilation and electrocautery.

Summary:

  • A novel technique utilizes selective jet ventilation under bronchofiberscopy to identify the intersegmental plane for resection.
  • This method selectively inflates the segment to be resected while deflating adjacent lung, creating a clear boundary.

  • Hybrid VATS segmentectomy was performed on patients with peripheral T1N0M0 lung cancer (≤2 cm) using this technique, dividing the intersegmental plane with electrocautery.

    • Impact:

    • Selective segmental inflation facilitates quick and easy identification of the intersegmental plane, ensuring accurate margins.
    • This technique allows for an appropriate surgical view despite the minimally invasive approach.
    • Improved visualization and margin control enhance the feasibility and safety of VATS segmentectomy for early lung cancer.
