In recent years, the subxiphoid approach has been used to avoid intercostal nerve damage in the field of thoracic surgery. A subxiphoid single-port thymectomy does not require sternotomy; it is associated with lesser pain because there is no intercostal nerve damage; and it provides excellent cosmetic outcomes. Furthermore, in 2014, the author and colleagues reported synchronous resection of bilateral pulmonary metastases by bilateral lung-wedge resection for bilateral metastatic lung tumors with a single 3-cm subxiphoid incision. In this method, a bilateral lung-wedge resection is performed synchronously without an intercostal approach and, thus, does not cause intercostal nerve damage and excels in aesthetic outcomes.
