Functional improvement after volume reduction: sternotomy versus videoendoscopic approach

Area of Science:

• Pulmonary Medicine
• Thoracic Surgery
• Respiratory Physiology

Background:

• Lung volume reduction surgery (LVRS) improves ventilatory mechanics in diffuse, nonbullous lung emphysema.
• The optimal surgical approach for LVRS remains a subject of debate.

Purpose of the Study:

• To compare perioperative data and functional outcomes between sternotomy and video-endoscopic approaches for LVRS.
• To evaluate the efficacy of different surgical techniques in improving lung function and physical fitness in emphysema patients.

Main Methods:

• Retrospective comparison of 15 patients undergoing sternotomy (Group I) versus 15 patients undergoing video-endoscopic surgery (Group II).
• Analysis of perioperative data, including mortality, chest tube drainage duration, and hospital stay.
• Assessment of functional results, including work of breathing, intrinsic positive end-expiratory pressure, and forced expiratory volume in 1 second (FEV1) at 3 months post-surgery.

Main Results:

• 30-day mortality was 2 patients (Group I) and 1 patient (Group II).
• Mean chest tube drainage and hospital stay were comparable between groups (8.7 vs 8.0 days and 12.3 vs 12.5 days, respectively).
• Significant improvements in work of breathing, intrinsic positive end-expiratory pressure, and FEV1 were observed in both groups at 3 months post-surgery (p < 0.05 for all).

Conclusions:

• Both sternotomy and video-endoscopic approaches for LVRS lead to substantial and comparable improvements in lung function and physical fitness.
• There were no significant differences in air leakage, chest tube drainage duration, or hospital stay between the two surgical methods.
