Abstract: Objective To evaluate the clinical effects and health economics of lung volume reduction surgery(LVRS), single lung transplantation(SLTx) and bilateral lung transplantation(BLTx) for patients with end-stage emphysema.
Methods A total of 61 patients with end-stage emphysema, including 39 patients who underwent LVRS(LVRS group), 14 patients who underwent SLTx(SLTx group), and 8 patients who underwent BLTx(BLTx group) from September 2002 to August 2008 in Wuxi People’s Hospital, were analyzed retrospectively. Lung function, arterial blood gas analysis and 6-minute walk distance(6-MWD)were assessed before their surgery and 6 months, 1-year and 3-year after their surgery respectively. Their 1-year and 3-year survival rates were observed. Cost-effectiveness analyses were made from a health economics perspective. Results Compared with their preoperative results, their mean forced expiratory volume in 1 second(FEV1.0)in LVRS group increased by 75%, 83% and 49% at 6 months, 1-year and 3-year postoperatively, by 176%, 162% and 100% in SLTx group, and by 260%, 280% and 198% in BLTx group respectively. Their mean forced vital capacity(FVC)in LVRS group increased by 21%, 41% and 40% at 6 months, 1-year and 3-year postoperatively, by 68% , 73% and 55% in SLTx group, and by 82%, 79% and 89% in BLTx group respectively. Their exercise endurance as measured by 6-MWD increased by 75%, 136% and 111% in LVRS group at 6 months, 1-year and 3-year postoperatively, by 513%, 677% and 608% in SLTx group, and by 762%, 880% and 741% in BLTx group respectively. The 1-year and 3-year survival rates after operation were 74.40% and 58.90% in LVRS group, 85.80% and 64.30% in SLTxgroup, and 62.50% and 50.00% in BLTx group respectively. The three years’ cost utility of SLTx group was significantly higher than that of BLTx group(1 668.00 vs.1 168.55, P< 0.05)and LVRS group (1 668.00 vs. 549.46, P< 0.05). Conclusion SLTx and BLTx are better than LVRS in improving patients’ lung function and exercise endurance for end-stage emphysema patients. LVRS is more cost-effective than SLTx and BLTx in the early postoperative period. With the development of medical technology and decreased expenses of lung transplantation and immunosuppressive agents, lung transplantation will become the first surgical choice for end-stage emphysema patients.
