Lung volume reduction surgery (LVRS) specimens reveal diverse pathologies, including emphysema and incidental findings like adenocarcinomas. This analysis highlights the importance of examining tissue from LVRS patients for comprehensive disease understanding.

Area of Science:

  • Pulmonary Pathology
  • Surgical Pathology
  • Thoracic Surgery

Background:

  • Lung volume reduction surgery (LVRS) is an established treatment for severe emphysema.
  • Pathologic evaluation of resected lung tissue is crucial for understanding disease progression and treatment outcomes.
  • Systematic analysis of LVRS specimens provides insights into the spectrum of pulmonary conditions managed by this surgery.

Purpose of the Study:

  • To systematically describe the pathologic findings in lung tissue resected during Lung volume reduction surgery (LVRS).
  • To identify clinically relevant and incidental pathologic lesions in patients undergoing LVRS for emphysematous lung disease.

Main Methods:

  • Retrospective review of stained tissue sections from 65 patients undergoing LVRS.
  • Analysis included hematoxylin-eosin and special stains.

  • Surgical technique (open, bilateral/unilateral) and patient demographics were recorded.

    • Main Results:

    • Histologic emphysema was predominantly moderate (72%) to severe (19%).
    • Microscopic bullae were present in 75% of specimens.
    • Clinically significant findings included three adenocarcinomas and one case of granulomatous bronchiolitis/pneumonitis; incidental findings were common, such as interstitial fibrosis (55%) and bronchiolitis (54%).

    Conclusions:

    • LVRS resected specimens show a broad range of pathologic findings, encompassing both expected emphysematous changes and unexpected lesions.
    • The increasing use of LVRS necessitates careful examination of specimens for potentially significant incidental findings, including malignancies.
    • Pathologic assessment of LVRS specimens is vital for comprehensive patient management and understanding disease heterogeneity.
