Abstract:Objective To summarize the clinical experience and lessons of thoracoscopic lung volume reduction in the treatment of severe emphysema. Methods The clinical data of 35 patients with unilateral lung volume reduction under thoracoscopy from January 2016 to May 2018 were analyzed retrospectively. Results Except one patient died of respiratory failure due to postoperative pulmonary infection,the rest of the patients were cured and discharged from the hospital.The clinical symptoms were significantly improved.FEV1 increased half a year after the operation compared with that before the operation ［(1.02±0.21)L vs (0.68±0.17)L,P<0.05］. ConclusionIt is the key to ensure the success of lung volume reduction surgery to strictly grasp the indications and contraindications of operation,design the operation path in advance according to high-resolution CT and radionuclide pulmonary ventilation and perfusion examination,and operate accurately and minimally.
