Surgical aspects and techniques of lung volume reduction surgery for severe emphysema

Lung volume reduction surgery (LVRS) has become an accepted procedure for palliative treatment of diffuse, nonbullous emphysema. Single or multiple peripheral segmental wedge resections of the most destroyed areas of the lungs are performed with the use of stapling devices, in order to decrease hyperinflation and restore diaphragmatic function. Median sternotomy, videoendoscopy or anterior muscle sparing thoracotomies have been used as surgical approaches. The functional improvement after bilateral resections exceed those after a unilateral approach. LVRS has demonstrated its potential as an alternative to transplantation, and with growing experience, the indications for the procedure have been widened. In selected patients with peripheral lung cancer who have been considered unsuitable for a surgical resection, the combination of both tumour resection and LVRS has succesfully been performed. In contrast to LVRS, laser surgery of the emphysematous lung has been abandoned in most institutions.
