Background: To present the technique of minimally invasive extended thymectomy performed through the uniportal subxiphoid approach, with double elevation of the sternum for nonthymomatous myasthenia gravis (MG).
Methods: Operative technique: the whole dissection was performed through the 4-7 cm transverse or longitudinal subxiphoid incision with use of videothoracoscope. The sternum was elevated with two hooks connected to the sternal frame (Rochard bar, Aesculap-Chifa, Nowy Tomysl, Poland). The lower hook was inserted through the subxiphoid incision and the superior hook was inserted percutaneously, after the mediastinal tissue including the major mediastinal vessels were dissected from the inner surface of the sternum. The fatty tissue of the anterior mediastinum and the aorta-pulmonary window was completely removed.
Results: There were four patients in the period 1.1.2017-30.4.2017. There was no mortality and morbidity.
Conclusions: The uniportal subxiphoid approach combined with double elevation of the sternum enabled very extensive thymectomy in case of thymoma.
