The Division of Cardiovascular Surgery performs operations for valvular disease, coronary disease, congenital heart disease, and aortic disease.
“Our department provides patient-oriented medical care as a leading minimally-invasive cardiovascular treatment center in Japan.”
Using endoscopically assisted small incision, we have actively performed heart surgery without involving sternotomy, which is an advanced version of minimally invasive cardiac surgery (MICS). As of the end of 2014, we have performed 700 cases of small incision heart surgery, the highest number of cases in Japan. In addition, aortic stent grafting, which was introduced in 2009, is implemented in about 90 cases annually. We have a complete system with which minimally invasive surgery can be performed to treat various types of cardiovascular diseases.

Our department covers not only the ear, nose, and throat areas, but also the head and neck areas widely, only excluding the brain, spine, and eyes. In particular, the Ear Operation Center, Head and Neck Operation Center, and Laryngeal Operation Center in our department play an important role in treating patients requiring high-level surgery, and more than 1,000 operations are performed annually.
We commonly perform minimally-invasive form- and function-sparing surgery that only requires short-term hospitalization. Operations available in our department are: hearing improvement surgery (e.g., tympanoplasty and stapes surgery) for chronic otitis media, chronic otitis media with cholesteatoma, or otosclerosis, skull base surgery for cranial base diseases (e.g., acoustic tumors and nasal/paranasal sinus tumors), facial nerve decompression for severe idiopathic facial palsy, endoscopic surgery for nasal or paranasal diseases, minimally-invasive surgery for salivary gland tumors, reconstruction for malignant head/neck tumors, and voice improvement surgery for laryngeal diseases. We also treat patients suffering from hearing loss, tinnitus, or hoarseness in cooperation with speech-language-hearing therapists and clinical psychologists.

The Department of Radiation Oncology mainly performs cancer radiotherapy.
In collaboration with various other departments, the best treatment strategy is selected for each individual patient from a wide range of both definitive and palliative options. We are equipped with two linear accelerators used to deliver external beam radiotherapy. 3D-CT planning is utilized to create treatment plans, and for selected cases, intensity modulated radiation therapy (IMRT) and stereotactic body radiation therapy (SBRT) are also frequently offered. We have a brachytherapy suite furnished to provide both low-dose-rate interstitial radiation therapy for prostate cancer, as well as high-dose-rate intracavitary radiation therapy for cervical cancer. For patients with painful bone metastases, intravenous injection of the radioisotope Strontium is available.

The Department of Urology treats both malignant and benign diseases. Main examples of the former are kidney, urothelial, prostatic, and testicular cancers, and those of the latter are renal failure (dialysis), illnesses requiring renal taransplantation, adrenal tumors, dysuria, urinary incontinence, prostatic hypertrophy, ED, infertility, and pediatric urologic diseases.
“Our department commonly performs minimally-invasive surgery, and provides various special outpatient services.”
In addition to laparoscopic surgery for kidney cancer, prostatic cancer, and adrenal tumors, we actively provide minimally-invasive treatments, such as transurethral enucleation with bipolar (TUEB), which is our new surgical technique to treat prostatic hypertrophy. Our hospital is a country-leading medical center when it comes to this surgery. In addition, patients in need of special outpatient services can consult our medical experts.

The Department of Plastic and Reconstructive Surgery mainly treats problems related to the form of the body surface. Examples of these problems are congenital abnormalities in the form of the body surface, deformity or deficits caused by injuries, and a lack of tissues due to the resection of malignant tumors.
“Our department aims to achieve perfect surgeries.”
Our main duty is to compensate for a lack of tissues due to congenital abnormalities, injuries, tumor removal performed through microsurgery, or operations on the skull, jaw, and face, using other tissues. We aim to perform minimally-invasive surgeries to achieve a successful form or functional reconstruction, while guaranteeing that the surgical scar will not be left at all.

The Division of Orthopedic Surgery treats diseases in motor organs, such as bones, joints, ligaments, muscles, spine, spinal cord, and peripheral nerves.
“Our goal is to provide world-class orthopedic surgery based on our fundamental and clinical researches.”
Our division, which is divided into 4 clinical groups (spine and spinal cord, upper limbs, lower limbs, and tumors), performs surgery in coordination with other surgical departments. We actively deal with motor system diseases that are deemed too difficult to treat in other medical centers, and performed more than 1,900 specialized surgeries in 2013. In addition, we provide special outpatient services related to orthopedic surgery, such as osteoporosis outpatient services, athlete outpatient services, and bone metastasis outpatient services.

The Division of General and Gastroenterological Surgery performs surgery for patients with diseases in digestive organs (e.g., the esophagus, stomach, intestine, liver, bile duct, and pancreas), mammary gland disease, or peripheral vascular disease.
“Our division deals with various both benign and malignant diseases in the field of general gastrointestinal surgery.”
Our medical staff with expertise in the field of general gastrointestinal surgery provide high-quality medical care in teamwork. Examples of these medical services are minimally-invasive laparoscopic or thoracoscopic therapy using advanced techniques, which has been performed since the 1990s, and treatment for markedly advanced, challenging malignant tumors involving multiple organs and vessels, which cannot be treated in other medical centers. In addition, multiorgan illness can be treated by disease-specific teams.

The Department of Gastroenterology and Hepatology treats diseases occurring in gastrointestinal tracts, such as the esophagus, stomach, duodenum, small intestine, and large intestine, and deals with disorders involving the liver, biliary tract, or pancreas.
“We provide patient-oriented medical services in cross-sectional cooperation.”
We provide medical care in cross-sectional cooperation with other facilities, such as the Department of General and Gastroenterological Surgery, Department of Radiology, Cancer Center, Center for Diagnostic and Therapeutic Endoscopy, and Immunotherapy Center. Our clinical personnel are divided into 6 clinical teams, each of which is in charge of the special fields of the upper gastrointestinal tract, lower gastrointestinal tract, oncology, liver, bile duct and pancreas, as well as endoscopy, respectively. Staff members on these teams, who have expertise in Gastroenterology and Hepatology provide healthcare services for both in- and out-patients.
