Abstract
We performed a thoracoscopic surgery for left lung cancer associated with thymoma under a median sternotomy and mediastinal lymphnode dissection using video-assisted mediastinoscope inserted through median sternotomy or trocars incision. A 63-year-old female was admitted with an abnormal shadow of anterior mediastinum on chest X-ray. The patient was undergone extended thymothymectomy through a median sternotomy and then left lower lobectomy and mediastinal lymphnodes dissection was done by using thoracoscope and video-assisted mediastinoscope (reverse mediastinoscopy), We in-serted the mediastinoscope into the subcarinal space and hilar space displacing the lung and the left atrium, and dissected the subcarinal and the hilar nodes. We conclude that the reverse mediastinoscopy is useful for dissecting the mediastinal nodes for a patient of lung cancer associated with thymoma.
