Lung Diseases
Conditions
Brief summary
Many thoracic surgeons tend to dissect the inferior pulmonary ligament (IPL) during upper lobectomy, which in theory reduces the free space in the upper thoracic cavity by increasing the mobility of the residual lung. However, the dissection of IPL may lead to bronchial deformation, stenosis, obstruction or lobe torsion, and distortion. Some studies have found that stenosis might be associated with chronic dry cough and shortness of breath, and could result in a significant decline in lung function. Moreover, the dissection of IPL may lead to greater surgical trauma and increase the incidence of complications. Therefore, this study tries to identify whether we should dissect or preserve the inferior pulmonary ligament during the thoracoscopic upper lobectomy.
Interventions
Patients will be categorized into two groups: the division group ,who will receive the division of the inferior pulmonary ligament, and the preservation group, who will not.For the dissection group, we will dissect the inferior pulmonary ligament during the surgery.
