Systematic video-assisted mediastinoscopic lymphadenectomy in the treatment of resectable non-small cell lung cancer / 中华胸心血管外科杂志

ABSTRACT

Objective This study was performed to assess the clinical feasibility of video-assisted mediastinoscopic lymphadenectomy in the treatment of resectable lung cancer.Methods Between March 2011 and May 2012,we retrospectively analyzed the data from 56 patients who underwent video-assisted mediastinoscopic lymphadenectomy(VAMLA).In patients receiving tumour resection subsequently,radicality of the previous mediastinoscopic dissection was controlled during thoracotomy.Results Mean operative time of video-assisted mediastinoscopic lymphadenectomy was(42.0 ± 13.5) min(range of 26-86 min).Mean number of resected lymph nodes was 12.4 ± 6.7 (range of 5-24).In video-assisted mediastinoscopic lymphadenectomy,the rates of lymph node dissection of stations 2,4,5,7,8 were 54.5％,92.7％,58.2％,100％,61.8％,respectively,there was no operative mortality and morbility.90.9％ patients achieved radical dissection.Conclusion Video-assisted mediastinoscopic lymphadenectomy is a clinically feasible procedure and provides more accurate staging of mediastinal node in lung cancer patients.It also plays an important role in minimal invasive surgery and neoadjuvant therapy.
