Surgical treatment of lung cancer consists of two elements: anatomical lung resection (segmentectomy, lobectomy or pneumonectomy) followed by mediastinal lymph node dissection (MLND). Since over last 15 years the growing rate of resection is performed by minimal invasive approach - video-assisted thoracoscopic surgery (VATS). The study is focused on the clinical and technical aspects of MLND during VATS lobectomy. The extension of lymph nodes resection is strictly specified. The main benefit of MLND for the patient is precise histopathological staging, which allows choosing the best therapeutic option of adjuvant therapy. MLND is related with potential minor and major complications (bleeding, increased volume of chest tube drainage, prolonged chest tube duration and hospital stay, chylothorax, left recurrent laryngeal nerve injury, injury of the bronchus, injury of the esophagus). The majority of complications are caused by thermal injury resulting from the use of heat-generating monopolar electrocautery that is commonly used during lymph nodes dissection. In addition, thermal energy generation in case of monopolar electrocautery may lead to systemic inflammatory response and increased surgical injury. High-energy sealing devices like LigaSureâ„¢ allow for dissection, coagulation and cutting with the single instrument. Compared to mechanical ligation techniques (vessel loops, clips) or monopolar electrocautery, LigaSureâ„¢ technology has been shown to reduce: intraoperative blood loss (in colorectal, gynecologic and urologic surgery), surgery time (in colorectal, gynecologic and urologic surgery), length of hospital stay (in gynecologic and urologic surgery). Investigators hypothesize that application of LigaSureâ„¢ in VATS anatomical resection may lead to diminished complications rate, lower systemic inflammatory response and shorter length of stay compared to monopolar electrocautery.
