Thymectomy has long been the mainstaytreatment for thymoma and other anterior mediastinal neoplasms, with radiation andchemotherapy as the adjuvant therapy. In recent years, minimally invasivethymectomy (MIT) has been reported to be an effective surgical approachinvolving less trauma, shorter hospital stay, potentially fewer complications,and rapid recovery; it has become an important way to treat thymic tumors. Thepast decade has also witnessed an increasing application of video-assistedthoracoscopic surgery (VATS) and robotic surgery in the field of thymoma. Inthis book, Minimally Invasive Thymectomy, the international leading experts inthe field were gathered to provide the state-of-the-art research on VATS thymectomyand robotic thymectomy. The book includes three sections relating to thefollowing topics: minimally invasive thymectomy, VATS thymectomy, and roboticthymectomy. We hope that this excellent compilation of highly focused chapterswill provide the surgeons and other interesting readers a deeper insight intoMIT.
