[Lung Volume Reduction Surgery for Severe Emphysema].

Lung volume reduction surgery( LVRS) is performed in patients with severe emphysema who do not respond to medical therapy. We report two cases of LVRS that resulted in favorable outcomes. We used a method in which the cyst wall is incised, the cyst base is covered with fibrin glue and polyglycolic acid (PGA) sheets, and the cyst wall is resected using an automatic suturing device. In the first case, respiratory failure was observed preoperatively, and home oxygen therapy was introduced. However, minimally invasive LVRS was performed using a thoracoscopic approach, resulting in a good outcome for the patient. In the second case, a giant cyst and pneumothorax coexisted, suggesting the difficulty of preoperative differentiation.
