Surgery for Masaoka-Koga I-II Thymoma

A 2-cm straight incision was made in the middle of the xiphoid process, the incision was used as a thoracoscope hole, and the xiphoid process could be removed if necessary. The surgeon used the oval forceps to release the left and right soft tissue gaps behind the sternum, from the anterior mediastinum tunnel. Two 0.5 cm extrapleural thoracic ports under the bilateral costal arches were created, and this incision was used as an operation hole. The thread puncture cone with a diameter of 0.5 cm was placed under the guidance of the finger.
