[Two cases of traumatic diaphragmatic hernia with atypical medical history].

We have recently experienced two cases of traumatic diaphragmatic hernia which has been repaired by surgery. The first case was a 58-year-old man who had suffered left upper abdominal injury with a branch in his childhood. Although he had never symptoms, chest X-ray showed abnormal shadow in the left lower lung field. Radiologic studies indicated that the great omentum was escaped into the thoracic cavity. On patient request, we performed primary repair of the diaphragmatic hernia on thoracotomy. The second case was a 56-year-old woman who had undergone a left nephrectomy for the left renal abscess. Seven months after the operation, she began to feel nausea and vomiting, and the symptom aggravated with time. Chest X-ray showed air bubbles in the left lower lung field. It proved to be a projection of the stomach into the thoracic cavity through the iatrogenic diaphragmatic injury. We successfully performed a repairment of the diaphragm with a mesh.
