[Surgical treatment for severe pulmonary emphysema]

Area of Science:

• Thoracic surgery
• Pulmonary medicine
• Cardiothoracic surgery

Background:

• Severe pulmonary emphysema causes debilitating exertional dyspnea.
• Volume reduction surgery (VRS) is an option for managing advanced emphysema.
• Two primary surgical approaches exist for VRS: median sternotomy and thoracoscopic resection.

Purpose of the Study:

• To compare the characteristics of median sternotomy versus thoracoscopic approaches in volume reduction surgery.
• To evaluate the trade-offs between invasiveness, patient tolerance, bleeding, and air leakage for each VRS method.

Main Methods:

• Surgical resection of peripheral lung tissue.
• Comparison of median sternotomy technique versus thoracoscopic technique.
• Assessment of intraoperative bleeding and postoperative air leakage.

Main Results:

• Thoracoscopic VRS is less invasive and better tolerated by patients in poor physical condition.
• Median sternotomy VRS is associated with heavier bleeding during surgery.
• Median sternotomy VRS demonstrates significantly less postoperative air leakage compared to thoracoscopic VRS.

Conclusions:

• The choice between median sternotomy and thoracoscopic VRS involves balancing invasiveness and postoperative complications.
• Median sternotomy may be preferred when minimizing air leakage is a priority, despite increased bleeding risk.
• Thoracoscopic approach offers advantages in patient tolerance for those with poor physical condition.
