Area of Science:

  • Thoracic Surgery
  • Pulmonary Medicine
  • Surgical Oncology

Background:

  • Deep pulmonary nodules with resection margins spanning multiple subsegments pose challenges for conventional lung-sparing surgeries.
  • Standard subsegmentectomy or wedge resection may be insufficient, often necessitating lobectomy for adequate margins.
  • The
  • split
  • operation was developed to address these limitations by facilitating lung tissue inflation.

Purpose of the Study:

  • To preliminarily assess the feasibility and safety of the "split" operation for specific pulmonary nodules.
  • To evaluate the surgical outcomes and postoperative recovery associated with this novel technique.

Main Methods:

  • A retrospective analysis of patients undergoing the "split" operation for deep pulmonary nodules.
  • Evaluation of operative parameters including duration, blood loss, and hospital stay.
  • Assessment of postoperative complications, pulmonary function, and imaging findings.

Main Results:

  • The "split" operation was successfully completed in seven patients without conversion to thoracotomy.
  • Median operative time was 219 minutes, median blood loss was 30 ml, and median hospital stay was 4 days.
  • No major complications occurred; 85.8% of pulmonary function was preserved at 3 months with well-inflated lung tissue.

Conclusions:

  • The "split" combined subsegmentectomy is a new, safe, and effective operative method for deep pulmonary nodules.
  • This technique allows for adequate resection margins in challenging cases, potentially avoiding lobectomy.
  • The procedure demonstrates good short-term outcomes and preserves lung function.
