Thymectomy has long been the mainstay treatment for thymoma and other anterior mediastinal neoplasms, with radiation and chemotherapy as the adjuvant therapy. In recent years, minimally invasive thymectomy (MIT) has been reported to be an effective surgical approach involving less trauma, shorter hospital stay, potentially fewer complications, and rapid recovery; it has become an important way to treat thymic tumors. The past decade has also witnessed an increasing application of video-assisted thoracoscopic surgery (VATS) and robotic surgery in the field of thymoma. In this book, Minimally Invasive Thymectomy, the international leading experts in the field were gathered to provide the state-of-the-art research on VATS thymectomy and robotic thymectomy. The book includes three sections relating to the following topics: minimally invasive thymectomy, VATS thymectomy, and robotic thymectomy. We hope that this excellent compilation of highly focused chapters will provide the surgeons and other interesting readers a deeper insight into MIT.
