Regarding endoscopic diagnosis/ treatment of early-stage alimentary canal cancer

In our department, there is a total of 5 staff members engaged in endoscopic medical care, including 2 medical specialists of digestive endoscopy. Our motto is to provide our patients with endoscopic examination which causes little pain. At patients’ request, we serve sedation to them by applying intravenous anesthesia in all cases. Especially in cases of colonoscopic examination, we perform endoscopic examination that causes little pain to patients, by using immersion testing to insert an endoscope, or supplying carbon-rich gas. Extirpation of colonic polyp is completed in one day. The upper and lower alimentary canal examination can be served at the same time, so please consult us when you undergo examination of the digestive tract as part of a through medical checkup or examination.
Regarding Endoscopic Submucosal Dissection (ESD): Surgical procedure has been the first choice in cancer treatment but with the growing availability of colonoscopic examination and gastric camera used in health exam and a through medical check up, the discovery rate of early stage cancer has increased, enabling patients to choose less invasive therapies. Especially leading the world in the field of stomach cancer which is relatively popular among Japanese people, it has devised a method of Endoscopic submucosal dissection enabling us to remove the lesion which had been difficult to be removed at one time in endoscopic resection. In 2007, early stomach cancer was covered by health insurance, followed by early esophageal cancer in 2009 and early bowel cancer in 2012.
In the department, we take responsibility for performing treatment such as, preoperative diagnosis, endoscopic resection, examination of degree of complete recover and in case of stomach cancer, pylorus eradication after the radical excision, and periodical follow-ups after the surgery.

Endoscopic diagnosis/Treatment for bile passage and pancreatic disease

As the population ages, bile duct stone, endoscopic diagnosis and pancreas malignancy are becoming popular diseases among people. We perform palliative treatment such as, gastroenterological endoscopic treatment for acute cholangitis and bile duct stone, endoscopic stent placement for biliary obstruction caused by malignant tumor. With introduction of ultrasound endoscope and small-bowel endoscopy, we will continue making efforts in expanding our services so that we can respond to further pathological lesions.

Palliative chemotherapy/ supportive care for advanced cancer

As the population ages, we are now living in an age where 1 out of 3 people die of cancer, and 1 out of 2 people develops cancer at least once in their entire life times. With that, there is also an increase in a number of patients who are diagnosed with advanced cancer difficult to be cured completely. Cancers of digestive system account for about half its ratio of them, particularly bowel cancer and pancreas cancer are on the rise. Even with these intractable and advanced cancers, the ratio of survival has improved by applying combined modality therapy which combines surgical therapy, anticancer drug treatment and radiation therapy. Especially in the field of anticancer drug, there has been an improvement in treatment results for cancers which had no effective treatment in the past, with molecularly-targeted therapeutic medicine being continuously developed and applied in a clinical setting. Also, side effects used to be difficult for patients have been eased by an improvement in supportive care, making patients able to continue treatment while maintaining to spend a ordinary life. However, standard treatmensts and adaptation in cancer treatment differ according to its original organ caused cancer, and the degree of progress, and they are advanced quickly, the importance of team medical care is being pointed out, to deal with growing complication and specialization in the treatment.
In our department, we aim to provide each patient with the best treatment possible by coordinating closely with the trauma department,the department of gastroenterological medicine, the department of general medicine, and allied health professionals.
In cases where radiation therapy is necessary, we serve it in cooperation with the department of radiation therapy/oncology center, Shonan Kamakura General Hospital, Okinawa Tokushukai healthcare corporation.

Regarding recruitment of senior doctor in training

In this department, we have a policy to practice professional education under the treatmentystems focused on provising overall treatment, in cooporation with the department of general medicine, and the trauma department. We widely recruit doctors with interests in cancer chemotherapy/palliative therapy and endoscopic therapy who are able work as subspecialists regardless of their own specialty (internal medicine specialist/ surgeon). Our focus is on doctors who were graduated from the medical school 3 to 5 years ago. The training period will be 3 to 5 years(negotiable), aiming at becoming medical specialist certified by The Japanese Society of Gastroenterology and The Japan Gastroenterological Endoscopy Society.
