Specific Techniques. At this time, the preferred technique is bilateral lung volume reduction. To accomplish it, surgeons use either an open approach, which uses a large incision in the chest area, or video-assisted thoracoscopy (VATS), which is less invasive. Either method is effective and has similar complication rates. Lines of staples are typically used to reduce lung volume.

The alternative technique is unilateral lung volume reduction. Some centers believe this approach may cause fewer complications and slower decline in benefits, although not all evidence supports its use over the bilateral method.
