Video-assisted thoracoscopic surgery non-grasping en bloc mediastinal lymph node dissection for the right side

Mediastinal lymph node dissection (MLND) through video-assisted thoracoscopic surgery (VATS) has been an aporia. It was one of the prime reasons that the effectiveness of VATS lung cancer surgery was queried, and no standardized procedure had been established. Several techniques of VATS MLND have been described concerning application of different instruments [cautery hook (CH), harmonic scalpel, Ultracision] (1-3).
