[Pulmonary emphysema: surgical indications]

Area of Science:

• Pulmonary Medicine
• Thoracic Surgery
• Respiratory Physiology

Context:

• Pulmonary emphysema treatment primarily involves lung transplantation or resection of emphysematous areas.
• Bullectomy is indicated for large bullae ( > 1/3 hemithorax) in diffuse emphysema, with mortality ranging from 0-10%.
• Traditionally, resection of small, poorly-defined bullae is contraindicated.

Purpose:

• To evaluate the efficacy and indications of surgical resection for pulmonary emphysema.
• To assess the outcomes of bullectomy in patients with large bullae.
• To explore the potential benefits of lung volume reduction in patients with smaller bullae.

Summary:

• Surgical resection, particularly bullectomy for large bullae, provides significant long-term subjective and objective improvements in dyspnea and spirometry for pulmonary emphysema patients.
• Recent findings suggest that lung volume reduction surgery may also benefit patients with smaller bullae, even those with severe obstruction, potentially due to increased elastic recoil.
• These surgical interventions are considered valuable alternatives to lung transplantation for managing pulmonary emphysema.

Impact:

• Surgical resection offers a viable treatment option for pulmonary emphysema, improving patient quality of life and respiratory function.
• The study challenges traditional contraindications for surgical intervention in emphysema, expanding potential treatment avenues.
• Lung volume reduction surgery is presented as a crucial consideration before pursuing lung transplantation for eligible patients.
