Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Several studies showed the association between vagus nerve and chronic cough. The bronchopulmonary vagal afferent C-fibers are responsible for cough, chest tightness and reflex bronchoconstrictions. It is expected that during the mediastinal lymph node dissection, the inevitable injuries to the pulmonary branch of vagus nerve is largely responsible for development of chronic cough. In other words, preservation of pulmonary branch of vagus nerve may reduce the incidence of chronic cough and relevant detrimental effects on quality of life.
Therefore, this prospective, randomized and controlled clinical study, aims to evaluate the effect of vagus nerve preservation on postoperative chronic cough in patients undergoing lobectomy with mediastinal lymph node dissection. In addition, the feasibility and oncologic safety of preserving pulmonary branch of vagus nerve during mediastinal lymph node dissection with minimally invasive surgery compared with conventional mediastinal lymph node dissection with minimally invasive surgery will also be investigated.
This trial will provide a new basis for oncologically feasible, safe and effective new surgical technique for mediastinal lymph node dissection in patients with early lung cancer undergoing minimally invasive surgery. Furthermore, the preventive effect of vagus nerve preservation on incidence of chronic cough will be objectively be proven and thus help to broaden the current knowledge of the role of vagus nerve and postoperative chronic cough.
