Lateral Lung Volume Reduction with Small Incision and Ligation for COPD:Report of 36 Cases / 中国微创外科杂志

ABSTRACT

Objective To investigate the efficacy of lateral lung volume reduction with small incision and ligation for the treatment of serious chronic obstructive pulmonary disease(COPD).Methods From April 1994 to May 2006,36 patients suffering from serious COPD complicated with severe emphysema underwent lateral lung volume reduction in our hospital.Small incision and ligation were used during the operation.Results After the surgery,6 patients developed pulmonary air-leak,and were cured after 180-minute to 5-day treatments(mean,1.6 days).No perioperative death in this series.One year after the operation,the patient had significantly higher FEV1 and PaO2,and lower TLC and RV than those determined preoperation [(839.9?76.0)ml vs(589.0 ?80.5)ml,t=18.451;(72?10)mm Hg vs(62?8)mm Hg,t=4.686;(5167.6?639.9)ml vs(6725.8?976.6)ml,t=8.116;(3062.4?722.0)ml vs(4329.6?669.9)ml,t=7.720;all P=0.000].In addition,they had significantly longer 6MWT than that before the operation [(306.0?24.8)m vs(223.8?36.7)m,t=11.135,P=0.000].Conclusion For the patients with COPD who had indications for lateral lung volume deduction,resection of emphysemic tissues by the procedure using small incision and ligation can improve their symptoms and physiological conditions.
