Lung volume reduction surgery for patients with pulmonary or esophageal neoplasms / 中华胸心血管外科杂志

ABSTRACT

Objective To evaluate the feasibility and efficacy of tumor resection combined with lung volume reduction surgery (LVRS) in pulmonary and esophageal patients.Methods 45 patients with lung tumor and 37 patients with esophageal tumor were di- vided into group A(tumor resection plus LVRS) and group B(tumor resection only) randomly.Group A patients underwent tumor re- section combined with LVRS.The target area was determined according to chest computed tomography and ventilation-perfusion scan- ning.The removed pulmonary tissues made up about 20%～30% of the unilateral lung parenchyma.All patients were followed up for 6～12 months.The pulmonary function,blood gas,dyspnea index and 6-min walk distance were compared.Results There were no death during perioperative period.Forced vital capacity in 1 second,PaO_2,PaCO_2,dyspnea index and 6-min walk distance of the group A were all better than preoperative ones,while group B patients had no statistical difference or slight decrease.Conclusion For some tumor patients with emphysema,simultaneous LVRS might provide better opportunity for surgical treatment,but also im- proved the post-operative quality of life.It widens the operative indication for tumor patients.
