[Successful Robotic Resection of Left Upper Mediastinal Tumor].

A man was diagnosed with a left upper mediastinal mass. The mass was located near the left subclavian vein, phrenic nerve, vagus nerve, left subclavian artery, and left brachiocephalic vein. He underwent a robotic surgery without additional approaches such as cervical approach on transmanubrial approach. Robotic surgery enabled to remove the tumor safely due to the highly flexible robot forceps under a 3-dimensional visual field. Robotic surgery may be effective for tumors in the upper mediastinum, where important blood vessels and nerves are closely present.
