This study shows virtual segmentectomy software is feasible and effective for lung cancer surgery. It aids in precise anatomical segmentectomy and achieving curative resection for patients.

Area of Science:

  • Surgical Oncology
  • Medical Simulation
  • Pulmonary Medicine

Background:

  • Anatomical segmentectomy is crucial for lung cancer treatment.
  • Accurate preoperative planning is essential for successful segmentectomy.
  • Existing methods may lack precision in defining surgical margins.

Observation:

  • A novel virtual segmentectomy simulation system was developed using CT imaging.
  • The software analyzes 3D bronchovascular structures to predict resection surfaces and margins.
  • The system was tested on patients with pulmonary metastases and multiple lung cancers.

Findings:

  • Virtual segmentectomy accurately predicted resection margins compared to actual specimens.
  • Surgical surface estimations correlated well with specimen and video comparisons.
