We retrospective reviewed minimally invasive video-assisted thoracoscopic surgery (VATS) to thymic diseases. These procedures were performed using intercostal and infrasternal approach with a sternum-elevator. Indications of this method are benign thymic lesions [mature teratoma, thymic cyst and myasthenia gravis (MG)] and small thymoma (non-invasive Masaoka stage I-II, less than 5 cm in diameter and nontouching to the left brachiocephalic vein). Fifty patients underwent VATS for 13 hemithymectomies (7 thymomas, 5 mature teratomas and 1 thymic cyst) and 37 extended thymectomies (25 nonthymomatous MGs and 12 thymomatous MGs). Conversion to sternotomy was required in 3 cases of nonthymomatous MG because of bleeding from thymic vein in 1 case and pleural adhesion in 2 cases. Four cases of thymomatous MG were successfully treated with partial lung resection and/or small pericardial resection by VATS. New bipolar vessel sealing system (LigaSure V) is safer and more useful than metal clip and ultrasonic coagulator in VATS for thymic vein sealing, extraction of upper poles of thymus and incision of mediastinal pleura near phrenic nerve. VATS thymectomy should be useful from the standpoint of less invasive, less pain, rapid recovery, and good cosmetic results.
