Primary experience of 13 cases of lung volume reduction surgery using domestic staplers and autologous tissue / 中国微创外科杂志

ABSTRACT

Objective To evaluate the results of lung volume reduction surgery (LVRS) using domestic staplers and autologous tissue. Methods Thirteen male patients received LVRS from June 2000 to March 2006 in this hospital. The age range was 56~68 years (mean, 60.5 years). The patients had a history of chronic obstructive pulmonary disease (COPD) for 2~16 years (mean, 11 years). The operation was performed under general anesthesia, with single lung ventilation. A muscle sparing thoracotomy in the 5th intercostal space was conducted. The “target area” was identified by combination of observation and palpation during operation and preoperative CT scans. The cutting edge was stapled with domestic staplers buttressed with autologous tissue. Results All the procedures were successfully accomplished. Follow-up observations for 8 months ~ 5 years showed no dyspnea and improved activities. At 6 months after operation, the FEV_1 and the PaO_2 were increased by 94.4%?21.2% and 12.5%?3.1%, while the RV and TLC were decreased by 24.1%?7.8% and 20.8%?5.1%, respectively. All the abovementioned parameters were significantly changed before and after operation (P
