Figure 2. Microanatomy-based standardization of upper mediastinal lymph node dissection. A, D: detaching the esophagus together with the lymphatic chain from the trachea and aggregating the lymphatic chain to the esophageal side; B, E, F: identifying the recurrent laryngeal nerve and lymph node dissection along the nerve from the central part to the peripheral part; C, G: final findings of upper mediastinal lymph node dissection
