Our clinic specializes in general internal medicine, digestive internal medicine, endoscope examinations and gastroenterology.
We provide our patients with regular colonoscopy and gastroscopy examinations, to help detect and prevent cancers of the stomach, colon and esophagus at an early stage. Ensuring our patients’ comfort during endoscopy examinations is our top priority. A Japan Gastroenterological Endoscopy Society specialist doctor will safely perform the endoscopy. We have successfully carried out 800 Endoscopic Submucosal Dissection (ESD) procedures. This is a highly complex endoscopic operation for removing early gastric cancer, colon cancer, and esophageal cancer. We work hard every day as a friendly, family clinic to ensure everyone in the community can attend our clinic with peace of mind.
- Strive to eliminate deaths from stomach cancer, colon cancer, and esophageal cancer (early detection will not affect prognosis)
- Provide comfortable endoscopy examinations with minimum pain
- Aim for accurate endoscopic diagnosis and treatment without any oversights.
Some of the special features of our clinic
Feature 1All endoscopy and surgical procedures are performed by specialists
At our clinic, endoscopic and surgical procedures are carried out by doctors with Japan Gastroenterological Endoscopy Society specialist and advisor qualifications and also Japan Society of Coloproctology specialist and advisor qualifications.
We have performed about 10,000 colonoscopies and about 1,000 polypectomies and mucosal resections, all carried out with high accuracy and minimum pain.
Feature 2A choice of transnasal or oral gastroscopy
You can choose to have a transnasal gastroscopy, which does not cause any gagging or an oral gastroscopy under sedation to suppress any pain.
Feature 3Colonoscopy with minimum pain and maximum comfort
We offer various options for pain reduction during colonoscopies.
First, sedatives and analgesics are used to relieve the pain and discomfort of the examination. In addition, by inflating the intestines with carbon dioxide, we can suppress any tension and nausea in the stomach after the examination.
Feature 4Endoscope system with magnifying function and special light (NBI)
Olympus’s latest endoscope system is equipped with a special NBI light, and a scope enlargement function, enabling observation of minute lesions without any oversights.
Feature 5One-day colorectal polypectomy
Colon polyps found at the time of examination can be removed at our clinic. There is no need for hospitalization for day surgery, which can reduce the risk of developing colorectal cancer in the future.
Feature 6Gastroscopy/colonoscopy available on examination day
To support patients who have to travel a long distance or who are busy with work, we have set up a system where you can have a gastroscopy or colonoscopy on the same day as your examination booked online or over the phone.
Feature 7Weekend endoscopy
For those who are busy on weekdays and are unable to come to the clinic,
we provide endoscopies and polypectomies on Saturdays and Sundays.
Feature 8Medical cooperation
If an abnormality is found in the endoscopy, we will refer you to a nearby hospital.
National Cancer Center Hospital, Cancer Institute Hospital of JFCR, Toranomon Hospital, Showa University Koto Toyosu Hospital and St. Luke’s International Hospital.
Doctor referral system
Our goal is to provide the best care for our patients, and continue to support their health. We would love to hear from physicians specializing in fields such as digestive internal
