Director of General Thoracic Surgery

We perform surgical procedures on all patients with respiratory diseases including lung cancer, emphysematous pulmonary diseases, myasthenia gravis, and mediastinal tumor. Our clinical section is designated as a center for pulmonary transplantation from a brain-dead donor/living donor. We also perform chemotherapy and radiotherapy on patients with progressive lung cancer, in cooperation with Respiratory Medicine and Department of Radiology, followed by radical surgery. We perform endoscopic (thoracoscopic) surgery on patients with early-stage lung cancer, striving to reduce the physical burden. The active use of endoscopic surgery on patients with mediastinal tumor and myasthenia gravis enables reduction of their surgical wounds and early discharge. We perform surgical procedures for radical cure while reducing the physical burden, being committed to promotion of advanced medical technology such as pulmonary transplantation.

Features

The number of annual inpatients is about 300, about 260 of whom undergo surgical procedures under general anesthesia. Annual by-disease numbers of patients, who undergo surgery are 100 for pulmonary cancer, 30 for metastatic pulmonary tumor, and 50 for mediastinal disease. About 70% of them undergo thoracoscopic surgery. We perform reductive surgery such as segmental resection, considering that the remaining pulmonary function may be conserved, and thoracoscopic surgery on patients with early-stage small lung cancer.
We have one of Japan’s leading outcomes in treatment for patients with mediastinal tumor, Myasthenia gravis (MG) and have performed extended thymectomy on about 500 patients with myasthenia gravis in 40 years. We conduct clinical research regarding the application of robot-assisted surgery for patients with thymoma, MG, and lung cancer to establish new surgical techniques. Our clinical section, one of seven facilities in which medical care services are provided for pulmonary transplantation, has performed pulmonary transplantation from brain-dead donors on 25 patients and pulmonary transplantation from living donors on 11 patients since 2000. Four supervisory doctors and seven medical specialists certified by the Japanese Association for Chest Surgery work together in our clinical section, which is designated as an educational center for surgeons specialized in general thoracic surgery and a center for certifying medical specialists in thoracic surgery.
