Gastrointestinal Endoscopy


(1) Overview

Gastrointestinal Endoscopy conducts endoscopic examinations/treatment of all gastrointestinal disorders. In particular, the department actively conducts endoscopic submucosal dissection (ESD: a treatment where the submucosa of the cancerous area is peeled off using an endoscope, fully resecting the lesion) for early esophageal, gastric and duodenal cancer and large intestine carcinoma. In particular, patients come not only from the Kanto region but also from great distances for ESD for duodenal cancer. The department also conducts capsule endoscopy (a test that is conducted by swallowing an endoscope in capsule form) for the small intestine and large intestine.

The department is equipped with a total of 11 endoscopy rooms, 7 rooms exclusively for general consultations (1st floor) and 4 rooms for comprehensive medical checkups (2nd floor). We make an effort to ensure that the endoscopy examination/treatment devices are always updated to the latest devices.

(2) Policy

Aiming for Treatment and Tests That Are Highly Accurate With Little Pain

Cancer, which is the main target disease for endoscopy examinations, is a disease that needs to be detected and cannot be overlooked. The Endoscopy Center strives for highly accurate endoscopy examinations to ensure that even early cancer is not overlooked. At the same time, the Center makes an effort to ensure endoscopy examinations/treatment with little pain by actively using anesthesia (sedatives) for the patients who wish to use them.

(3) Our Strengths

Numerous Cases

The annual total number of ESD cases for esophageal, gastric and duodenal cancer and large intestine carcinoma is approximately 900 cases, and the department boasts extensive experience in treating numerous cases. In addition, the department conducts approximately 11,000 upper endoscopy examinations per year and approximately 6,200 lower endoscopy examinations per year.

Emergency Response 24 Hours a Day, 365 Days a Year

Including nights and holidays, the department responds to the needs of emergency patients 24 hours a day, 365 days a year. The department is setup to handle sudden hematemesis and melena as well as bleeding after an endoscopic procedure at any time.

Accepting Trainees From Around the World

Many physicians who aspire to “master a high level of endoscopic skills” come to observe and train in Gastrointestinal Endoscopy at the hospital. Trainees come to learn not only from throughout Japan, but also from around the world, including China, Europe, Russia, and Brazil.

Conducting ESD With Transnasal Endoscopy

The department conducts ESD with transnasal endoscopy (an endoscope inserted through the nose) for early stage gastric cancer.
Ordinarily, ESD for early stage gastric cancer is conducted under anesthesia by inserting an endoscope through the mouth (transoral endoscopy). However, with elderly patients, the risk of complications caused by the stress of anesthesia is high.
Meanwhile, ESD via transnasal endoscopy does not require sedation with anesthesia. For this reason, we have created a structure to ensure that even elderly patients are able to safely undergo ESD treatment. Patients who were found to have early stage gastric cancer but had to give up on treatment because they were “elderly” come to the hospital from considerable distances.

Taking the Patient’s Wishes Into Consideration and Using Anesthesia to Alleviate Pain

In Gastrointestinal Endoscopy, if the patient wishes to do so, we actively use anesthesia (sedatives) when conducting examinations and treatment. After the procedure, patients are asked to rest in the recovery room until they are fully awake from the anesthesia. In the recovery room, safety management is thoroughly in place, and the room is equipped with monitors to enable an immediate response in the event of a sudden change in the patient’s condition.


Message for Our Patients

If you are currently being treated by a physician at another hospital or clinic, please bring a “patient referral document (referral)” to inform us of the progression of your condition. This will enable us to gain an accurate understanding of your condition, eliminating unnecessary tests and reducing the number of outpatient appointments.
As many patients come to Gastrointestinal Endoscopy at the hospital, some patients may be concerned that there may be a long time between the initial consultation and treatment, but this is not the case. Although it depends on the case, we are aiming for a setup that ensures that patients are able to receive an endoscopy examination/treatment within approximately one to two weeks after their initial outpatient consultation. The hospital looks forward to receiving patients who seek endoscopy examinations and treatment.
