[Left traumatic diaphragmatic hernia in the postoperative state of lung cancer: report of a case].

We report a case of left traumatic diaphragmatic hernia in the postoperative state of the lung cancer. A 68-year-old man underwent video-assisted partial resection of the left lung for lung cancer. One year after the operation, he experienced an accident of falling from a tree. Chest radiograph and chest computed tomography revealed the stomach herniating into the left thoracic cavity. An emergent operation was performed by the abdominal approach. The stomach was returned into the abdominal cavity, and the hiatus in the central tendon of the left diaphragm was primarily sutured. The postoperative course was uneventful.
