We also offer Helicobacter pylori eradication treatment.

For gastroscopy, we conduct a thorough examination not only of the esophagus, stomach, and duodenum but also of the pharynx and larynx, enabling the early detection of lesions amenable to endoscopic treatment. In colonoscopy, colorectal polyps can be removed on the spot. If gastrointestinal cancer is detected, we promptly refer patients to our affiliated hospitals, including the Cancer Institute Ariake Hospital, Toranomon Hospital, and university hospitals.

For patients who have difficulty taking oral laxatives for colonoscopy preparation, we offer an alternative plan where the laxative is administered via gastroscopy, eliminating the need for oral intake.

  This course allows for a high-precision gastroscopy and colonoscopy to be performed together in one session. For those who have difficulty taking laxatives, we also offer a no-laxative option. Basic Plan: After taking a laxative at the hotel or in the clinic, both gastroscopy and colonoscopy will be performed simultaneously. No-Laxative Plan: During gastroscopy, a laxative is directly administered into the duodenum using an endoscope, eliminating the need for oral laxative intake. ※ After the laxative is administered, it takes approximately 2 hours for bowel movements to cleanse the intestines. Colonoscopy will be performed afterward. As a result, the total time spent in the clinic will be around 4 to 5 hours.
