Lung volume reduction surgery: a cost and outcomes comparison of sternotomy versus thoracoscopy.
It remains unknown whether it is better to perform lung volume reduction surgery (LVRS) through video-assisted thoracoscopy (VATS) or sternotomy. This study compares both approaches in terms of surgical and patient outcomes as well as the associated costs. All patients undergoing LVRS from 1995 to 1997 at one institution by a single surgeon (PFW) were investigated. Preoperative, postoperative, and cost data were obtained from medical and financial records. A total of 42 patients with severe emphysema underwent LVRS (19 via sternotomy and 23 via thoracoscopy). Both groups were comparable preoperatively. Comparison of intraoperative times revealed VATS takes longer to perform (sternotomy, 118 +/- 29 minutes; thoracoscopy, 168 +/- 20 minutes). Postoperatively, the sternotomy patients had more days on the ventilator, more days in the intensive care unit, more days with an air leak, and longer hospital stays. In both groups, the majority of patients reported improvement in oxygen dependence as well as quality of life. Neither surgical approach conferred any long-term medical advantage; however, the average total hospital costs and charges were reduced in the VATS group (average cost: VATS, $27,178; sternotomy, $37,299). This study concludes that 1) LVRS seems to be beneficial for selected patients with end-stage emphysema; 2) postoperative morbidity and length of hospital stay are decreased in the VATS group; 3) long-term improvement in postoperative pulmonary function is not influenced by surgical approach; and 4) the overall charges and costs of the VATS approach is less than that of sternotomy.
