I divide my career as a neurosurgeon into three stages.
The first stage is from entering Professor Dr. Shozo Ishi’s department of Neurosurgery, Juntendo University till becoming a board certified neurosurgeon. During this stage I did research on delayed neuronal death in hippocampus CA1 after short-term ischemia at National Institutes of Health in the United States. I reported that disinhibition to the CA1 neurons induced by derangement in GABA metabolism was related to delayed neuronal death in the hippocampus CA1.
The second stage is Matsumura General Hospital. I developed my neurosurgical techniques at this stage under Professor Dr. Kiyoshi Sato’s direction. Dr. Sato also offered me opportunities to do clinical and experimental researches at Juntendo University. I assumed the post of the director of Matsumura General Hospital and had a very hard time maintaining functions of the hospital because the new doctor clinical training system just started.
The third stage is Juntendo University Urayasu Hospital. Since Dr. Masanori Ito, former professor of Neurosurgery and I moved to Juntendo University Urayasu Hospital, new surgical equipment and techniques have been introduced. Dr. Ito started spinal surgery under microscope. Dr. Senshu Nonaka, an endovascular specialist introduced coil embolization for cerebral aneurysms and thrombectomy for acute stroke. Dr. Hisato Ishii, associate professor began endoscopic transnasal removal for pituitary adenomas. Dr. Takamoto Suzuki, assistant professor started endoscopic third ventriculostomy for non-communicating hydrocephalus. Advances in surgical technology have made us develop the quality in neurosurgical practices. I was given opportunities to work for the doctor clinical training center and the medical safety. I was impressed by the young residents growing well through clinical training. We proposed “Medical Team Approach” for the trouble cases that are difficult to solve by only the medical staffs in charge. I started Brain Dock in the department of General Medicine in 2017 and wish to spread Brain Dock in order to prevent stroke and dementia.
I feel very happy to be back to Juntendo and reach retirement at Urayasu Hospital which is one of the hospitals in my alma mater, Juntendo University. I wish further development of Juntendo University in the medical service and research.
