Thoracoscopic extended thymothymomectomy was performed using sternum lifting method effectively in two patients with stage II thymoma. Under general anesthesia, the patients were intubated with a double lumen tube with the neck and upper abdomen extended in the supine position. A six-centimeter skin incision was made at the site of the xyphoid process and the backside of the sternum was excoriated from the mediastinum . A five-centimeter collar incision was made and then the sternum was lifted using vessel loops through the backside of the sternum. After the bilateral upper poles of the thymus were ligated and divided from the thyroid, the left brachiocephalic vein was taped and the thymic veins were ligated and divided. Then the thymus was excoriated from the left brachiocephalic vein . The upper pole of the thymus was grasped and pulled to the caudal side with the forceps . The thymus was excoriated from the aorta, superior vena cava, pericardium and mediastinal pleura . As a result, the thymoma and thymus were removed from the site of the xyphoid process. The bilateral phrenic nerves were the resecting margin of the mediastinal pleura. The operating times were 199 and 271 minutes and the volumes of bleeding were 40 and 130g . Analgesics were given during the period of thoracic drainage for one patient, and both were discharged on the fifteenth postoper ative day. There were no complications from the operation and no recurrence has been observed for about two years.
