Our Departments



Gastroenterology

At the Gastroenterology Department, four doctors are in charge of providing medical care to outpatients and inpatients. All the doctors can cover the entire scope of gastroenterology.
In endoscopic examination, we make it less painful and uncomfortable wherever possible and strongly recommend intravenous anesthesia (Dormicum) to those who feel anxious about the examination.
Our extensive scope of endoscopic treatment includes emergent hemostasis for gastrointestinal hemorrhage, ligation and sclerotherapy of esophageal varices, endoscopic papillotomy and lithotripsy for gall stones, stent placement in malignant biliary stenosis, and colon polypectomy. We closely coordinate with our Surgery Department to treat early digestive cancers, and the ESD is included as a treatment option.
We have been placing our emphasis on abdominal ultrasonography since the start of our hospital, and our doctors take initiatives of examinations conducted with ultrasonographers. We are dedicated to complying with requesting doctors’ demands and promptly feeding back the results to clinical fields.
One of our strengths lies in diversified liver disease therapies.
In recent years, many acute hepatitis B patients visit our hospital, and we provide appropriate treatment and guidance to prevent the spread of the disease.
As for chronic hepatitis C, treatment options have increased with the advent of the interferon-free therapy. We provide appropriate treatment in timely fashion by closely observing each patient’s conditions and offer a number of both interferon-free and interferon therapies.
Percutaneous radiofrequency ablation and transcatheter arterial chemoembolization (TACE) are our treatment options for inoperable liver cancers.
Our scope is not limited to the above-mentioned therapies, and we offer a wide range of medical care of the gastrointestinal system including eradication of H. pylori and treatment of recently controversial diseases such as NASH.

Pulmonary Medicine

The Pulmonary Medicine Department is for patients who suffer ‘breath shortness,’ ‘wheezing,’ ‘persistent cough,’ ‘much sputum,’ or ‘blood-stained sputum,’ or who were pointed out for abnormalities in chest X-rays.
We offer medical care for diversified diseases such as lung tumors, lung infections, allergic or immunological diseases, chronic obstructive pulmonary diseases, interstitial pulmonary diseases, and sleep apnea. The department can conduct advanced respiratory examinations such as respiratory function test, chest CT scan, bronchoscopy, and polysomnography.
We determine details of examinations and treatment plans by respectfully taking patients’ requests into consideration and proceed with treatment while carefully consulting with patients and their families.

Cardiology

The Cardiology Department has a system to promptly respond to a wide range of disorders such as chest troubles, palpitation, or syncope in close cooperation with the specialized outpatient sections, emergency sections, and laboratories.
The department can conduct electrocardiography, treadmill exercise test, echocardiography, ultrasonography, cardiac nuclear medicine examination, and cardiac CT scan; cardiac catheterization and percutaneous transluminal coronary angioplasty to treat ischemic heart diseases such as angina or myocardial infarction; and endovascular treatment for lower-limb arteriosclerosis obliterans.
We apply radiofrequency myocardial ablation using 3D cardiac mapping to treatment of tachyarrhythmia. In addition, we started treatment for atrial fibrillation by using a cardiac cryoablation system in March, 2016, and the number of treated cases exceeds 120 per year. We can offer a wide range of treatment of cardiovascular disorders. For example, cardiac syncope and bradycardia are diagnosed with ambulatory electrocardiography, head lift test, and implantable loop recorders and treated with MRI-compatible pacemaker implantation.

Endocrinology and Metabolism

The Endocrinology and Metabolism Department treats lifestyle diseases such as metabolic diseases (such as diabetes, hyperlipidemia, and hyperuricemia) and endocrine diseases (such as thyroid or adrenal disorders).
We offer impatient diabetes education in which we maintain ‘close dialogue between participating patients and medical staff’ so that the patients can confront their diseases and improve their lifestyle habits.
Doctors, nurses who are certified diabetes educators、dietitians, pharmacists, clinical technologists, physiotherapists, and dental hygienists cooperate with each other to exchange information and discuss about diabetic conditions, diets, exercises, health management, and foot care.
Patients can take exercises at the fitness facility adjacent to the hospital during the education.

Neurology

We diagnose degenerative diseases such as dementia and Parkinson’s disease by head CT scan, MRI, or cerebral perfusion scintigraphy. If a patient is difficult to visit the hospital as an outpatient, he/she must be admitted for approx. 1 to 2 weeks for diagnosis or approx. 2 weeks for medication adjustment for Parkinson’s disease and rehabilitation.
We can assess carotid artery stenosis that leads to cerebral infarction or scrutinize a cause for juvenile cerebral infarction. We use a transcranial Doppler equipment to diagnose right-to-left shunt such as patent foramen ovale without using transesophageal echocardiography.

Nephrology

The Nephrology Department provides comprehensive medical care to patients suffering renal diseases or renal dysfunction ranging from the early stage to renal failure to care after kidney transplant. Our excellent staff have a strong sense of responsibility.
  1. As a kidney center (Nephrology, Transplant Surgery, and Urology), we diagnose and treat nephritis, chronic kidney diseases, and acute and chronic renal failures, introduce and maintain dialysis treatment, respond to complications, conduct extracorporeal circulation therapy (hemocatharsis therapy, absorptive purification, blood component removal, and plasmapheresis), treat severe multiple organ dysfunction, and conduct kidney transplants.

  2. IgA-nephropathy-specialized outpatient: Established in Sep. 2008; directed by Dr. Osamu HottaFor IgA nephropathy, we closely cooperate with the ENT Department to actively conduct tonsillectomy + steroid pulse therapy. We also employ tonsillectomy for patients of recurrent IgA nephropathy after kidney transplant or dialysis patients suffering this disease as a primary disease and waiting for kidney transplant.

  3. Nephritis patients, chronic kidney disease patients, dialysis patients, and post-transplant patients with complications are admitted to the hospital for treatment.We operate 16 Nephrology and 4 Transplant Surgery clinical paths and actively examine other departments’ inpatients in close coordination.

  4. CKD (Chronic kidney disease) cooperation path
    We issue cooperative notebooks to facilitate smooth communications with cooperative doctors.

  5. Dialysis therapy
    We naturally introduce the therapy to necessary patients and keep close cooperation with other departments in the hospital (40% of dialysis inpatients are originally admitted to other departments) and neighboring dialysis institutions to comply with requests of dialysis patients suffering complications.Shunt problems: We cooperate with the Vascular Surgery Section and employ long-term catheterization.

  6. Kidney transplant
    We started admission of patients for two weeks after kidney transplantation in 2007 and living renal transplantation in Arp. 2009. We currently conduct living renal transplantation twice per month since Feb. 2010. The donors are followed up as CKD patients after transplantation.

Surgery

The Surgery Department provides comprehensive surgical care, specializing in surgical management of various digestive cancers, endocrine/breast surgery, vascular surgery, surgery of benign diseases such as hernia, appendicitis, cholelithiasis, or anal diseases such as hemorrhoid or anal fistula, diagnosis by upper/lower GI endoscopy, and endoscopic surgery.

Digestive Surgery

We mainly treat cancers originated in digestive tracts such as the esophagus, stomach and large intestine, and offer multidisciplinary care ranging from diagnosis to post-operative anti-cancer therapy and radiotherapy specialized in the respective organs.
We provide medical care optimum for each stage while focusing on minimally invasive procedures by actively utilizing endoscopy and laparoscopy.
We often apply chemoradiotherapy and palliative care to unresectable recurrent cancers to improve or at least maintain QOL. Laparoscopic surgeries are also frequently used for inguinal hernia and acute appendicitis.

Hepato-Biliary-Pancreatic Surgery

We conduct multidisciplinary care for primary hepatic cancers, metastatic hepatic cancers, or hepato-biliary cancers by operative treatment such as hepatectomy. We also apply multidisciplinary care to pancreatic cancers by using various surgical treatment such as pancreaticoduodenectomy, distal pancreatectomy, and regional lymph node dissection. These approaches as well as post-operative chemotherapy improve treatment outcomes.

Breast/Thyroid Surgery

Treatment of breast cancers includes breast-conserving surgery and cytoreductive surgery without lymph node dissection by specifying indication. More specifically, we conduct surgery, chemotherapy, molecular targeted therapy, hormone therapy, and radiotherapy. For thyroid diseases, our surgery scope includes surgeries of benign and malignant tumors and parathyroidectomy to treat hyperparathyroidism.

Benign Disease

We conduct surgeries for inguinal hernia, appendicitis, cholelithiasis, and anal diseases such as hemorrhoid or anal fistula. Various repairing methods including laparoscopy are used to treat hernia. Laparoscopy is used to treat appendicitis and cholelithiasis wherever possible for its esthetic advantages since only a small incision at the umbilical part is necessary for the surgery, resulting in less post-operative wound pain and less noticeable scar.

Vascular Surgery

We treat systemic arterial and venous diseases (except for intracranial and cardiac/coronary arteries, ascending aorta and aortic arch). The latest fluoroscopic apparatuses and operating tables required for hybrid therapy are installed in this section.
We are especially focusing on revascularization- and vascular access-related surgeries for critical limb ischemia. Laser therapy for varicose vein is also available.

Endoscopy (upper/lower GI)

An outpatient consultation section for endoscopy has been established, and we promote endoscopic diagnosis of upper and lower gastrointestinal tracts and endoscopic surgeries to completely resect cancers at applicable stages without open surgery. We are also well experienced in colon polypectomy.

Others

Female doctors are in charge of examination of the breast and anal since some may be reluctant to be examined by male doctors.

Orthopedic Surgery

The Orthopedic Surgery Department with highly specialized staff conducts artificial hip replacement surgery, artificial knee joint surgery, spine surgery, hand surgery, and foot surgery including treatment of bone fractures and injuries.
We conduct emergency surgeries of traumas, arthroscopic surgeries for hand and elbow joints, and minimally invasive artificial joint replacement surgeries for artificial hip/knee replacement surgeries, thus reducing time for recovery thanks to post-operative rehabilitation.
We have many surgery experience in meniscal tear and cruciate ligament rupture of the knee by endoscopic surgery using the latest devices, attaining early discharge.
We employ techniques to minimize damage to muscles in lumber spine surgeries and use microscopic guidance to conduct minimally-invasive cervical spine surgeries.

Neurosurgery

The Neurosurgery Department diagnoses and treats diseases that require surgical treatment among the entire scope of nervous system diseases including the brain, spinal cord, peripheral nervous system and their appendages (such as blood vessels and bones).
In a course of multidisciplinary primary inpatient care for stroke patients, we have established the Stroke Section to work as a team with the Neurosurgery, Neurology, and Rehabilitation Departments.
We also operate the Stroke Care Center consisting of the Stroke Care Unit (SCU) to provide intensive care to patients immediately after the onset of stroke, acute beds, and Comprehensive Community Care Ward.

Characteristics

  1. Systematic readiness to accept stroke patients so that thrombolytic agent, t-PA, can be administered within an hour from a visit
  2. Establishment of the Stroke Care Unit (SCU) and Stroke Unit (SU) to provide intensive initial care to stroke patients
  3. Diagnosis of cerebral infarction types and determination of care plan at the early stage of visit by emergency MRI
  4. Enhancement of the quality of care by mutual complement among the Neurosurgery, Neurology, and Rehabilitation Departments
  5. Start of rehabilitation by Rehabilitation staff within 3 days after the onset of stroke
  6. High home return rate of stroke patients
  7. Intravascular surgery such as thrombolytic therapy, stent placement, and cerebral aneurysm coil embolization treatment to treat cerebrovascular stenosis or occlusion
  8. Emergency surgery for cerebral hemorrhage or subarachnoid hemorrhage
  9. Safe surgeries under the guidance of surgery navigation system and intraoperative cerebral angiography

Dermatology

  • We cover an entire scope of dermatology.
  • Patients suffering pruritus associated with hepatic or renal disorders often visit our hospital.
  • We have no specialized outpatient section but offer care of venereal diseases such as syphilis and condyloma.
  • We conduct no surgery, plastic surgery or laser treatment.
  • We admit no inpatient to this department.
  • We accept patients by appointment only.

Urology

The Urology and Transplant Surgery Department always has two doctors for practice. The Urology is in charge of treating diseases related to the urinary tract and male genitalia. In outpatient, we mainly conduct pharmacotherapy for strangury due to prostatomegaly and frequent urination due to overactive bladder, detailed examination for hematuria detected in ordinary test, detailed examination for an elevated prostate tumor marker, and urinary tract infections such as urinary stone or cystitis. For urinary system malignancies of the kidney, urinary tract, bladder, and prostate, we actively conduct minimally-invasive treatment such as laparoscopic surgery in cooperation with Tokyo Women’s Medical University.
As a kidney center, we actively promote care of renal diseases in cooperation between Nephrology, Transplant Surgery, and Urology Departments. We started living renal transplantation in fiscal 2009 and conduct approx. 20 transplantations per year. We conduct surgeries in cooperation with the kidney transplantation team of Urology at Tokyo Women’s Medical University and provide hemocatharsis therapy before transplantation and medical care after transplantation in cooperation with our Nephrology Department to materialize high-quality medical transplantation.

Gynecology

The Gynecology Department treats women-specific diseases, or diseases of uterus, ovary, oviduct, and vagina. Since we have no obstetrical facility, we do not offer prenatal checkup or medical care for diseases related to childbirth or pregnancy. We are dedicated to ensuring a place where only women suffering gynopathies can be relaxed in such an environment and comfortably spend time with us.
Two doctors are in charge of outpatients, and we have equipment required for gynopathy testing, treatment, and surgeries.
We especially focus on minimally-invasive surgeries such as laparoscopic or hysteroscopic surgeries so as to be women-friendly and cause least surgical scar. We actively employ endoscopic surgeries such as a suspension-type laparoscopic resection in which only a lesion such as a benign tumor or uterine leiomyoma is removed through two or three small incisions without making a large scar in the abdomen; or hysteroscopic surgery in which uterine submucous myoma is removed by an endoscope inserted through the vagina.
While such minimally-invasive surgeries cannot be applied to all cases, we are dedicated to selecting therapies optimum and less painful for patients.

Ophthalmology

The Ophthalmology Department provides medical care in the entire scope of ophthalmology and conduct surgical treatment.

Cataract surgery

Cataract is a clouding of the eye’s lens, resulting in partial blindness or low vision. We make a small incision of approx. 2.4 mm in the cataract surgery. Patients are usually required to stay overnight, but may go home on the day of surgery according to their conditions. To treat both eyes, patients require hospitalization twice. Astigmatism correction lenses and multifocal intraocular lenses are also available.

Diabetic retinopathy

Diabetic retinopathy is a disease with fundus hemorrhage, vitreous hemorrhage, retinal detachment, macular degeneration, or glaucoma and may lead to loss of vision in a severe case. Treatment options include intravitreal injection or local injection and retinal photocoagulation, a vitreous surgery is conducted when required for a severe case.

Glaucoma

Glaucoma is a disease narrowing the field of vision, resulting in loss of vision if highly progressed. Early detection and early treatment start are essential for glaucoma. We usually administer eye drops, medication, laser treatment, or surgery. Continuous treatment is indispensable for glaucoma.

Epiretinal membrane, macular hole

Epiretinal membrane disorder is a disease in which an unnecessary membrane is formed at the center (macula) of the retina through which we usually see things and things are seen distorted in your field of vision or visual acuity lowers. Macular hole is a disease with a hole in macula and the center of visual field looks dark. Both diseases require vitreous surgeries.

Age-related macular degeneration

Age-related macular degeneration is a disease in which an irregular blood vessel is formed in the macula in the center of the visual field and causes edema or hemorrhage with effusion. Things are seen distorted, or visual acuity lowers. It can be treated with intravitreal injection. After injection, periodic visits and treatment are indispensable.

Obstruction of the central and branch retinal veins

A retinal vein is clogged, causing fundus hemorrhage. Visual acuity suddenly lowers, or things are seen distorted. We treat it with intravitreal injection, sub-Tenon injection, or retinal laser treatment and may select a vitreous surgery if required.

Ebtropion, entropium ciliarum, ptosis, and pterygium

We conduct surgeries for ebtropion, entropium ciliarum, ptosis, and pterygium.

Ear, Nose, and Throat (ENT)

The ENT Department diagnoses and treats diseases of ears, noses, throats, and necks. Doctors, nurses, and laboratory technicians are stationed in the morning except for Tuesday and holidays for patients at the age of 16 or higher.

Outpatient

By taking advantages of the appointment-only system, we take sufficient time for patient-friendly consultation with less waiting time. With equipment such as hearing and equilibrium testing equipment, nasopharyngolaryngoscopes, electronic endoscopes with NBI, and rhinomanometry equipment, we always keep in mind to provide prompt and accurate diagnosis and treatment.
We offer physiotherapy for dizziness if required.
We accept people physically handicapped in terms of auditory sense, equilibrium function, speech utterance function, or masticatory function.

Inpatient/surgery

We treat sudden deafness or facial paralysis with steroids. Since we will promptly respond to diseases that require emergency admission such as acute tonsillitis, peritonsillar abscess, nasal bleeding, or dizziness, please consult with us for an unscheduled visit of in case of emergency.
Our surgery options include tonsillectomy, nasal polyp resection, radical endoscopic rhinosinusitis surgery, microscopic laryngomicrosurgery, and neck surgery.
We refer neoplastic diseases and malignant diseases to radiotherapy or outside specialists.

Dentistry and Oral Surgery

The Dentistry and Oral Surgery Department mainly provides care for patients who are difficult to be treated by practitioners in the dentistry and oral surgery field and emergency patients. We set outpatient practice in the day practice hours on weekdays and ordinary surgeries in Tuesday afternoon. We consist of dentists and dental hygienists and have inpatient beds. We use exclusive instruments and tools for each patient.

Rehabilitation

The Rehabilitation Department provides medical rehabilitation for patients with motility disturbance. Doctors, physiotherapists, occupational therapist, and speech therapists are stationed in this department.

Inpatient

We prevent bed-ridden conditions by improving the activities of daily living (ADL) and support patients to return to their homes.
The rehabilitation program is shared and performed by doctors, physiotherapists, occupational therapist, nurses, and social workers (MSW).

Outpatient

Rehabilitation is basically conducted for inpatients. For outpatients, we accept consultation on admission to the Rehabilitation Department, equipment for rehabilitation, or acquisition of the physical disability certificate. We offer Botox therapy in parallel with rehabilitation to reduce stiff muscle (muscular spasm) due to sequelae of stroke.

Physiotherapy

We improve motion and ambulatory ability of patients and actively promote early ambulation.

Occupational therapy

We conduct functional training for upper limbs and trunk and activation training of higher brain functions as well as training for daily living activities and housework activities.

Speech therapy

We conduct training of patients with speech impediment such as aphasia (disability of language abilities such as hearing, reading, speaking, and writing) or dysarthria (disability of clear speaking due to awkward movement of the mouth and tongue) and with higher brain dysfunction (disturbance of memorization or attention deficit). In case of eating disorders or dysphagia, we conduct contrast swallowing radiography to assess the conditions before starting training.

Anesthesiology

The Anesthesiology Department is in charge of anesthesia control during surgeries and pain control for perioperative outpatients and inpatients. Anesthesiologists certified by the Japanese Society of Anesthesiologists are stationed in the department to comply with various emergency requirements.

Anesthesia for surgeries

  • Anesthesia is customized according to the lifestyle and QOL of each patient.
  • Related departments and sections cooperate with each other to attain optimum perioperative control so that even elderly patients and those who suffer severe complications can undergo surgeries safely and without concerns.
  • Since we have no pediatrics and obstetrics, we do not conduct surgery and anesthesia of children below school age and expectant and nursing mothers in principle.

Perioperative outpatient

The perioperative outpatient practice is conducted to grasp conditions of patients before surgeries and obtain informed consent based on sufficient information.

Pain control

We provide pain control only to our inpatients on their request.
* We provide it to outpatients only in the perioperative period.
