Internal Medicine

  • This department provides medical treatment covering the entire field of internal medicine.
  • Because internists specializing in “gastroenterological medicine,” “cardiology internal medicine,” “respiratory medicine” and diabetology/metabolism” belong to this department, through their close cooperation, we provide comprehensive medical treatments for patients suffering from multiple diseases.
  • Department of Infectious Diseases” and “Department of Neurology” are established as two independent departments to treat infections and neurological diseases, respectively. They take a collaborative approach to treat patients as needed. For more details, please read their pages.


  • Although the department of neurology is correctly recognized by the general public in the United States and Europe, compared with other medical departments, it seems to be a department that is not yet familiar to the Japanese and requires some more time to promote their understanding. In Japan, the department of neurology was first established as an independent special medical department in around 1967. Currently, almost all the university hospitals and large-scale hospitals in local communities have the department of neurology. (In the future, the department of neurology will be renamed as the department of neurological medicine.) The “department of neurology” was established as an independent medical department in Tokyo Metropolitan general hospitals in October 1994 when New Ebara Hospital was founded.
  • In this department, the physicians specializing in neurology treat disorders of the brain, spinal cord, peripheral nerve, muscle and autonomic nerve. The main symptoms include consciousness disturbance/higher mental dysfunction (aphasia (impairment of the ability to speak and understand others), apraxia (difficulty in performing ordinary movements because of confusion), agnosia (loss of ability to recognize finger and body parts), dementia (loss of cognitive functioning), convulsive seizure, movement disorder (paralysis of the limbs, ataxia, muscle stiffening or relaxation, involuntary movement including shaking in the limbs, impaired walking and standing, slurred speech, masticatory disturbance, swallowing disturbance, etc.), sensation disturbance (sense of smell (hyposmia), sense of vision (abnormal visual acuity), sense of hearing (hearing impairment, tinnitus), skin sensation (numbness, obtundation, nerve pain), deep sensation (lightheadedness)) and other various dysfunctions (headache, orthostatic hypotension, dizziness, syncope, dysuria, etc.).
  • These symptoms may not be due to primary impairment of brain/spinal cord/peripheral nerve/muscle but due to secondary impairment associated with internal disease or bone disease. Neurologists play an important role in making a differential diagnosis of these diseases and referring patients to the appropriate medical departments.


  • Department of Surgery provides team medical care for gastroenterological diseases (so-called gastrointestinal diseases, esophageal diseases, liver diseases, gallbladder diseases, pancreatic diseases, etc.) and respiratory diseases (bronchial/pulmonary diseases). This department also provides treatments for diseases of the mediastinum, mammary gland and thyroid gland; hernia (rupture) and hemorrhoid/anal diseases.
  • Generally, minimally invasive surgery using laparoscope or thoracoscope (surgery that leaves small surgical wounds and causes less stress on patients) is selected to treat relatively early detected cancer or benign disease, while, to treat advanced cancer, more invasive surgical treatment supported by highly advanced technology is provided by the excellent staff members and a multidisciplinary approach using such surgical procedure in combination with radiation therapy and chemotherapy is also taken to provide appropriate treatment.
  • Department of Surgery puts emphasis on communication with patients and their families to provide the optimum treatment for each patient. Frequent communication between elderly patients and the special medical staff members enables provision of thoughtful treatment for the patients.

Orthopedic Surgery

  • At this department, orthopedic surgeons provide treatments mainly for diseases and injuries of the spine (cervical/thoracic/lumbar spine), pelvis and extremities. We also provide treatment for systemic diseases including osteoporosis, rheumatoid arthritis and gout. At this hospital, orthopedic surgeons specializing in treatment of spine diseases, diseases of the joints of the extremities (particularly artificial knee/hip joint) and sports disorders provide patients with practical and effective treatment.
  • Orthopedic surgeons who conduct spinal operation make special efforts to provide minimally invasive and safe surgical treatment using the spinal cord monitoring, navigation system, microscope and endoscope. Because a minimally invasive approach requiring a small skin incision is generally adopted in these procedures, even elderly patients stay hospital for about one week after surgery for lumbar spinal stenosis or cervical myelopathy.
  • Fracture fixation, artificial joint replacement, ligament reconstruction and osteotomy are used in the operations of the hip joint and knee joint. For the patients suffering from injuries and those who underwent artificial joint replacement, the medical staff members specializing in rehabilitation provide appropriate rehabilitation programs soon after surgery.
  • Because orthopedic surgeons treat a very large variety of diseases, patients suffering from any symptoms not related to the head, chest and abdomen but related to bone, muscle, joint, ligament and nerve can consult with them.


 Department of Pediatrics promotes cooperation with the local medical institutions, medical association, university hospitals, National Center for Child Health and Development and handicapped children’s facilities and provides acute medical care and nighttime emergency medical care for children. This department is positioned as a pediatric department of a core hospital in Jonan Area that accepts emergency medical admission of children at night and on holidays.
 Department of Pediatrics provides acute medical care, acute infection care requiring isolation (admission to the special ward for treatment of infection) and special medical care for various conditions including pediatric allergic diseases. This department has the special outpatient departments to provide treatment for allergic diseases, cardiovascular diseases, kidney and urinary tract diseases and impairment in growth and development, as well as prophylactic vaccination for children.
 At this department, the pediatricians treat various pediatric allergic diseases including bronchial asthma, food allergy, urticaria, anaphylaxis, atopic dermatitis and allergic rhinitis. The patients placed on elimination diet as a treatment for food allergy undergo the examination of growth status. The opportunities of nutritional guidance and educational instruction are also provided and EpiPen is prescribed as needed. Depending on individual condition, the patients with food allergy visit the outpatient department or stay in hospital to undergo food tolerance test. The children who can not receive prophylactic vaccination at general medical institutions because of allergic diseases are referred here for vaccination.
 In cooperation with local medical institutions, administrative bodies and educational institutions, through learning from patients, Department of Pediatrics provides the optimum healthcare supported by the latest medical evidence for respective patients and carefully observes growth and development of children with their parents.

Plastics&Reconstructive Surgery

  • General public and even healthcare professionals occasionally find it difficult to correctly recognize plastic surgery because of difficulty in differentiating plastic surgery from orthopedic surgery and cosmetic surgery. Plastic surgery is explained as follows: “plastic surgeons treat physical ugliness such as congenital or acquired change in shape or color of body surface, morphologically and anatomically normalize such a condition using surgical procedures, and finally adjust individuals to the society (Takuya Onizuka, Professor Emeritus, Department of Plastic and Reconstructive Surgery, Showa University School of Medicine). At Department of Plastic Surgery, medical specialists treat a large variety of apparent physical defects using surgical procedures.
  • This hospital promotes cooperation between medical institutions and accepts many patients referred from the hospitals/clinics in the nearby wards including Ota Ward, Shinagawa Ward and Meguro Ward. At this hospital, physicians direct special efforts to treat cerebrovascular disorder and degenerative disease and thus the ages of the patients treated at Department of Plastic Surgery are relatively high. Accordingly, the plastic surgeons have many opportunities to treat skin ulcer and pressure ulcer. Through close cooperation with various medical departments of this hospital, Department of Plastic Surgery takes a multidisciplinary approach to treat diseases and injuries. Patients who intend to consult with the plastic/aesthetic plastic surgeons are to make an appointment at the outpatient department of plastic surgery.


At this department, ophthalmologists treat a large variety of diseases of the eye including cataract, diabetic retinopathy and age-related macular degeneration. This department also has two special outpatient departments, Outpatient Department of Fluorescein Fundus Angiography and Outpatient Department of Photocoagulation.
Although Department of Ophthalmology is generally regarded as a medical department providing treatment only for diseases of the eye, many of these diseases reflect systemic diseases including diabetes. Therefore, this department accepts many patients referred from other medical departments including Department of Internal Medicine.
Operations are scheduled on Tuesday and Thursday. Many patients undergo cataract surgery either as “day surgery” or as “in-hospital surgery” depending on their conditions.
This hospital has a hyperbaric oxygen chamber classified as Class 2 device to treat central retinal artery occlusion with hyperbaric oxygen. One course of treatment including seven sessions requires 7–9 day hospitalization. A patient undergoing hyperbaric oxygen therapy enters/leaves the room along with other patients. If he/she visits here in the morning, he/she can receive the initial treatment on the same day. Please make an appointment in advance at this department because the schedule of treatment should be adjusted according to the availability of the hyperbaric oxygen chamber.


  • At this department, otolaryngologists treat ear symptoms including difficulty in hearing, tinnitus and ear pain; nasal symptoms including nasal congestion and runny nose; laryngopharyngeal symptoms including sore throat, dull feeling in the throat, hoarseness and swallowing difficulty; facial nerve palsy and head and neck tumor. We make efforts to take a holistic approach to treat each patient and provide treatment contributing to improvement of quality of life (QOL).
  • This department is characterized by variety of treatments for sudden deafness. It is acute severe hearing loss of unknown origin. Because its cause still remains unknown, no treatment supported by highly scientific evidence has been established. Among the treatment options for sudden deafness, corticosteroid therapy and high-pressure oxygen therapy have been suggested to be effective. Ebara Hospital is one of three medical institutions that have hyperbaric oxygen chambers for treatment of multiple patients. Therefore, patients with sudden deafness can receive corticosteroid administration in combination with high-pressure oxygen therapy and stellate ganglion block while they stay at this hospital for two weeks. According to the scientific data, introduction of high-pressure oxygen therapy within two weeks after onset of sudden deafness is effective in improving deafness and initiation of this therapy shortly after its onset is recommended. The data obtained from the analysis of treatment results at this department showed improvement of hearing ability could not be expected in patients who started high-pressure oxygen therapy more than one month after onset of sudden deafness. Accordingly, high-pressure oxygen therapy is indicated in the patients who visited this department within one month after onset of sudden deafness.
  • This department provides treatment for middle ear diseases. To treat children suffering from acute otitis media or secretory otitis media, otolaryngologists select antimicrobial agents and provide treatments in line with the guidelines. Otolaryngologists also provide surgical treatments for patients suffering from chronic otitis media, chronic otitis media with cholesteatoma or otosclerosis (admission period: 4–5 days). The elderly people may have middle ear diseases in addition to age-related hearing loss. In this case, they may experience severe hearing impairment but appropriate treatment can significantly improve their QOL.
  • At this department, otolaryngologists provide treatment not only for ear diseases but also for swallowing difficulty. We perform fiberoptic endoscopic examination of swallowing and contrast examination of swallowing to evaluate the detailed pathological conditions of swallowing difficulty. Moreover, we provide swallowing rehabilitation guidance and surgical treatment for swallowing difficulty. To ensure satisfactory outcome of surgical treatment such as surgery for improvement of swallowing or prevention of aspiration, appropriate postoperative rehabilitation and improvement of nursing environment are indispensable. In cooperation with Department of Rehabilitation, Department of Neurology and the oral/swallowing care team, this department takes a multidisciplinary approach to provide comprehensive medical care for patients before and after treatment. At this department, otolaryngologists direct special attention to management of tracheostomy orifice because patients with these orifices often have swallowing difficulty. We treat narrowing/granulation of tracheostomy orifice, select an appropriate tracheostomy tube and provide necessary treatment according to individual conditions.
  • Otolaryngologists conduct endoscopic surgery to treat chronic sinusitis. Using the state-of-the-art navigation/surgical device, we treat patients requiring difficult reoperations and those with eosinophilic sinusitis in a safe and effective manner (admission period: approximately 1 week).

Anesthesiology/Pain Clinic

Generally, Department of Anesthesiology provides anesthetic management for the patients in the operating rooms, pain management for the patients admitted to the wards, and sickbed management in the ICU. In the outpatient clinic (Pain Clinic), anesthesiologists provide the treatments in the field of pain management including nerve block.


 Ebara Hospital is one of a few general hospitals having the department of psychiatry with inpatient facilities. This department provides inpatient treatment at the open ward in addition to the regular outpatient treatment and day-care services. It also provides special medical care such as psychiatric liaison consultation care and palliative care. These efforts contribute to provision of smooth medical treatment at each department.

 Inpatient treatment is provided for patients with various psychiatric disorders including schizophrenia, emotional disorder and anxiety disorder. The available inpatient facility, however, is the open ward alone and, in principle, patients with relatively mild symptoms are accepted here. This hospital has not only sufficient and multifaceted human resources including physicians, nurses, psychologists, pharmacists and psychiatric social workers but also advanced medical devices for various examinations and treatments. These advantageous medical resources, characteristic of general hospitals, are utilized to provide thoughtful medical care. Because the psychiatrists have sufficient clinical experience and can utilize the accumulated know-how, we may provide special medical care for patients with serious psychiatric disorders in addition to the above basic medical care. We also make the most of the advantages of general hospitals and effectively treat complications. The mean length of hospital stay is approximately one month and intensive treatment is provided for each inpatient for a short period of time. As in the case of inpatient treatment, outpatient treatment is provided for patients with a large variety of psychiatric disorders. The patients suffering from psychiatric disorders requiring special care including personality disorder, alcohol/drug dependence, developmental disorder, epilepsy and pediatric psychiatric disorders may be referred to appropriate medical institutions. Please be forewarned of this condition.

 As one of leading mental health care centers in Ota Ward, Department of Psychiatry, Ebara Hospital, continues to make the maximum effort to meet various needs of community people. This department offers various medical services for the patients having mental disorders, their families and local care providers.

Infectious Diseases

Ebara Hospital was first established as an infectious disease hospital having a medical department specializing in treatment of infectious diseases. Later, this medical department was renamed Department of Infectious Diseases.
This hospital has been designated as Designated Medical Institution for Class 1 and Class 2 Infectious Diseases where patients suspected of or diagnosed as suffering from Ebola virus disease or Middle East respiratory syndrome (MERS) are admitted to receive treatment.
Generally, this department provides treatment of tropical diseases including malaria, dengue fever and typhoid fever. In the routine practice, however, the physicians treat a large variety of infectious diseases including infectious enteritis (so-called food poisoning), pneumonia, urinary tract infection, cellulitis, infectious endocarditis, bacterial meningitis, adult viral diseases (measles, rubella, chickenpox, mumps), rickettsiosis and parasitic infection.
The special outpatient department provides various medical services including health counseling such as prophylactic vaccination and prescription of preventive medicine, and preparation of the medical certificate required for overseas study.
Infection Control Team (ICT) and Antimicrobial Stewardship Team (AST) are organized as multidisciplinary medical teams. As the members of these teams, the medical professionals promote control of in-hospital infection and antimicrobial resistance (AMR).


Neurosurgery is a medical field where physicians conduct diagnostic examinations of various neurological diseases requiring surgical treatment and provide treatments for such diseases. These neurological diseases include the diseases of the central nervous system (brain, spinal cord), some of peripheral nerve diseases and diseases of their appendages (blood vessel, bone, muscle, etc.). This hospital has positioned “acute medical care for cerebrovascular disease” as a priority issue and, in cooperation with Department of Neurology, Department of Neurosurgery provides the emergency medical care service for 24 hours a day, 365 days a year. As part of the efforts to provide multidisciplinary treatment for patients with stroke, this hospital established Stroke Unit, a special ward for treatment of stroke, in October 2003. Department of Neurosurgery, Department of Neurology and Department of Rehabilitation organized a team to provide team medical care for these patients at the ward. For patients who can not return home after completion of acute-phase treatment, recovery rehabilitation hospitals or convalescent hospitals are recommended according to their pathological conditions and family circumstances. They are transferred to these hospitals so that they can receive medical care seamlessly. In this manner, this hospital promotes close cooperation with local hospitals.
In principle, Department of Neurosurgery is in charge of treatment of hemorrhagic diseases including subarachnoid hemorrhage and cerebral hemorrhage, while Department of Neurology is in charge of treatment of cerebral infarction. In May 2017, this department introduced thrombus retrieving therapy to treat acute cerebral major vessel occlusion. Neurosurgeons use catheter-based cerebral endovascular therapy to treat patients suffering from acute-stage cerebral infarction that responded poorly to tissue plasminogen activator (tPA).

Breast Surgery

【Medical examination】

  • Breast surgeons examine various breast diseases including breast cancer.
  • On the initial consultation, each patient undergoes palpation, mammography, ultrasonography (echography) and fine-needle aspiration cytology, if indicated.
  • To make a definitive diagnosis, needle biopsy, stereotactic mammotome biopsy (for microcalcification), galactography and selective resection of the mammary duct are additionally conducted as needed. If a diagnosis of breast cancer is made according to the result of needle biopsy, immunostaining is added to identify the subtype of breast cancer.
  • If a patient is diagnosed with breast cancer, the patient undergoes diagnostic imaging examinations including CT and MRI scan. In cooperation with radiologists, breast surgeons conduct these examinations to evaluate metastases to other organs and lymph nodes and the extent of cancer in the breast, and then determine the treatment strategy with consideration for the results of pathohistological examinations including fine-needle aspiration biopsy and needle biopsy.
  • Generally, a patient undergoes early treatment such as surgical procedure or preoperative chemotherapy about two weeks after the initial consultation.


Three treatments including 1) surgical therapy, 2) drug therapy and 3) radiation therapy are combined to treat breast cancer.

  1. Surgical therapy
    Department of Breast Surgery offers sufficient counseling to patients and takes collaborative approach with Department of Plastic Surgery to provide various treatments including one-stage breast reconstruction and two-stage breast reconstruction as well as breast conserving surgery and sentinel lymph node biopsy using two-mapping method.
  2. Drug therapy
    Although cancer can be resected by surgery, cancerous cells may spread throughout the whole body. Breast surgeons predict this possibility in consideration of the pathological results and attempt to eradicate such cancerous cells and prevent recurrence of breast cancer. For this purpose, we select chemotherapy, endocrine therapy or molecularly targeted drug therapy as needed and provide postoperative adjuvant therapy for patients.
    Oncotype DX test (genetic test) is additionally performed to select appropriate postoperative adjuvant therapy. Some patients need preoperative chemotherapy according to the histological diagnosis based on needle biopsy and the results of preoperative diagnostic imaging. Preoperative chemotherapy may contribute to reduction of lump in the breast and avoidance of total breast resection. In this case, the breast can be saved.
    Drugs used for treatment and the period of drug therapy differ from patient to patient. Physicians carefully examine each patient and provide appropriate standard treatment.
  3. Radiation therapy
    Radiologists provide radiation therapy for patients. Radiation therapy is indicated in the patients who are judged to be requiring this treatment after breast-conserving surgery and who had many lymph node metastases or bone metastases.
  • Breast cancer is malignancy that can be cured as long as it is detected in the early stage.
    In principle, a patient with breast cancer enters hospital on the day before surgery and leaves hospital after 3–7 day admission after surgery.
    Persons who have palpable lumps or recognize any change in the breast are advised to visit Department of Breast Surgery.


  • Department of Rehabilitation addresses the major medical issue and provides special rehabilitation treatment for patients delivered here shortly after onset of cerebrovascular disease and patients placed on perioperative care after cancer surgery.
  • The members of this department include physicians, physical therapists, occupational therapists and speech therapists.
  • At this department, the individual rehabilitation goal is determined on the basis of comprehensive evaluation and intensive rehabilitation treatment is provided for each patient. It is hoped that as many patients as possible have the opportunities to participate in effective rehabilitation programs.
  • This hospital promotes collaboration in the field of rehabilitation medicine with other hospitals to meet patients’ needs.


  • Department of Dermatology promotes collaboration with two nearby universities (Showa University and Toho University) and local clinics and fulfills its role as a local core medical institution.
  • Dermatologists treat patients with trouble of all body parts covered with skin from head to toe. We also treat diseases of the oral cavity and external genitals. This department provides treatments for a large variety of pathological conditions, for example, eczema, irritation, athlete’s foot, tinea cruris, insect bite, herpes, urticaria, pigmented patch, mole, tumor, acute viral exanthema such as measles/rubella/chicken pox, connective tissue disease and skin lesions associated with visceral diseases.
  • Dermatologists prescribe oral medicine to treat male pattern alopecia. People who are conscious of their thin hair can consult with medical specialists here.
  • We also conduct examinations of atopic dermatitis, contact dermatitis and other allergic diseases. (Laser therapy for hemangioma is not available here.)
  • If a patient with skin disease needs major surgical treatment, the treating dermatologist may consult with a plastic surgeon. If a patient with skin disease has any systemic trouble, the treating dermatologist may consult with an internist. Because close collaboration has been established between Department of Dermatology and other medical departments at this hospital, patients with skin trouble are advised to visit this department first.


  • Department of Urology provides treatment for the following diseases: urinary tract/genital cancers (renal cancer, renal pelvic cancer, ureteral cancer, bladder cancer, prostatic cancer, testicular tumor, etc. ), dysuria (prostatic hyperplasia, neurogenic bladder, overactive bladder, interstitial cystitis, etc.), urolithiasis, urinary tract infection (pyelonephritis, cystitis, prostatitis, epididymitis, etc.), adrenal tumor, male menopause and sexual dysfunction.
  • Urologists conduct prostate biopsy (short-term admission needed), surgeries for benign diseases including transurethral resection of prostate for prostatic hyperplasia and surgical treatments for urinary tract/genital cancers.
  • This department has established close collaboration with in-hospital medical departments and local medical institutions including university hospitals and provides treatment according to the informed consent policy. If any patient requests for medical treatment not available here or intends to obtain second opinion, he/she will be referred to an appropriate hospital.



Obstetricians and midwives examine patients at Department of Obstetrics.
Because a midwife provides seamless care for a pregnant woman from her initial outpatient visit to her admission, the trust relationship between them can be enhanced. A midwife can take an appropriate response to a pregnant woman who hesitates to consult her treating obstetrician about her personal problem.
At 24 weeks of pregnancy, a pregnant woman undergoes complete fetal ultrasound examination.
At her request, her partner is allowed to attend to her during delivery.
This department accepts the reservation for delivery if a pregnant woman intends to return to her parent’s home to give birth. (The number of cases to be accepted is limited.)


  • Department of Gynecology provides less invasive surgeries such as laparoscopic surgery and hysteroscopic surgery to reduce physical stress on patients and accelerate postoperative recovery.
  • Laparoscopic sacrocolpopexy (LSC) using mesh and tension-free vaginal mesh (TVM) technique are increasingly introduced as highly effective procedures with low incidence of recurrence in treating pelvic organ prolapse (genital prolapse such as vaginal cystocele, uterine prolapse or rectocele).
  • In cooperation with other physicians, gynecologists examine various treatment options for gynecological malignancy including surgical therapy, chemotherapy and radiation therapy and select the optimum treatment for each patient. In principle, each patient receives the second and subsequent sessions of chemotherapy at the outpatient chemotherapy center.


Our hospital provides the following examinations and treatment.

*CT scan
*MRI scan
*Routine X-ray examination
*Pantomography/bone mineral measurement (panoramic tomography, bone densitometry)
*Isotope examination
*Mammography (breast imaging) examination
*Radiation therapy


Department of Dentistry & Oral Surgery provides treatment particularly for the patients suffering from the following pathological conditions requiring special treatments that can not be provided at general dental clinics in local communities.

  • Diseases in the field of dentistry and oral surgery (complicated exodontia such as wisdom tooth extraction, dental infection, jaw deformity, malignancy, osteomyelitis of the jaw, etc.)
  • Serious physical complications (cardiopulmonary-cerebral complications, hepatorenal disorder, infection, diabetes, coagulation disorder, etc.)
  • Persons with disabilities (cerebral palsy, psychosomatic disease, dementia, etc.)
  • Oral function management associated with various diseases (perioperative care for patients with cancer, palliative care, sleep apnea syndrome, etc.)
  • Dysphagia rehabilitation (stroke, period after surgical treatment of malignancy, etc.)
  • Others (patients with strong vomiting reflex, patients with dental phobia, etc.)

This department has established close collaborative relationship with many local dental clinics so that the above patients can receive appropriate treatment. These patients may be referred to reliable cooperative dentists as needed.
