Gastroscopy, also known as upper endoscopy, is a procedure where an endoscope is inserted through the mouth or nose to observe the mucous membranes of the pharynx, esophagus, stomach, and duodenum in real-time using a camera attached to the endoscope. This examination allows for detailed assessment not only of cancer but also of the presence and extent of inflammation and ulcers.

If any suspicious areas are identified during the procedure, tissue samples can be taken using the endoscope for further examination through a process called biopsy. Additionally, it is also used for testing for the presence of H. pylori bacteria.

At our clinic, we offer a less discomforting experience by providing options such as “transnasal endoscopy” that passes through the nose and using sedatives. We have incorporated various measures to ensure that patients feel at ease when undergoing gastroscopy.

• Sensation of discomfort or pain in the throat and difficulty swallowing
• Heartburn and stomach heaviness
• Frequent burping, especially with a sour taste
• Pain in the stomach or upper abdomen
• Decreased appetite and weight loss
• Nausea and vomiting
• Feeling of fullness or bloating
• History of chronic gastritis, gastric ulcers, or duodenal ulcers
• Passage of black, tarry stools
• Abnormal findings in a barium examination
• Individuals over 50 years of age seeking to prevent diseases and early detection

If you experience any of these symptoms or conditions, or if you belong to the mentioned age group, we encourage you to consult with us promptly. Gastroscopy allows for the simultaneous observation of the mucous membranes of the pharynx, esophagus, stomach, and duodenum.

At our clinic, we prioritize ensuring a comfortable and minimally painful experience during gastroscopy. We perform the procedure with great care and attention, striving to receive feedback from many patients such as “This was the easiest and least painful experience I’ve had.” We are committed to making continuous efforts to achieve this goal. We understand that some individuals may have developed aversions to undergoing gastroscopy due to past experiences or discomfort even with sedation. In such cases, we are prepared to explore solutions to address their concerns. We warmly welcome those individuals to visit our clinic.

Early detection of cancer requires highly specialized techniques. With gastroscopy performed under sedation, it becomes possible to detect lesions that were difficult to identify using a nasal camera, thus enabling early detection of cancer.

①Pain-Free Gastroscopy with Anesthesia (Sedation)

We offer pain-free gastroscopy using anesthesia (sedation). In addition to applying gel or spray local anesthesia to the nose and throat before inserting the endoscope, we can also administer sedation. This allows you to experience a drowsy, semi-sleep state, which reduces sensations of pain and fear. It is particularly recommended for those who are prone to gag reflex or wish to undergo gastroscopy with ease.

Transnasal Endoscopy is also available

In gastroscopy (upper endoscopy), we offer both the “Oral Endoscopy,” which is inserted through the mouth, and the “Transnasal Endoscopy,” which uses an extremely thin scope inserted through the nose. The “Transnasal Endoscopy” option provides several benefits, as it reduces the likelihood of gag reflex and allows communication with the physician during the procedure, even without the use of sedation. Patients can also view the actual endoscopic images.

② Same-Day Gastroscopy Available:

We offer the possibility of same-day gastroscopy if you make a reservation. It is possible to undergo both the initial consultation and the gastroscopy on the same day. However, please be aware that you must fast from 9:00 PM the night before the procedure.

③ Saturday Gastroscopy Appointments Available:

For those with busy weekdays, we also provide gastroscopy appointments on Saturdays and Sundays. As Saturday appointments are in high demand, we highly recommend making reservations via phone or through our website.

➃ Simultaneous Gastroscopy and Colonoscopy:

You can have both gastroscopy and colonoscopy on the same day. This offers significant benefits, such as only needing to adhere to dietary restrictions and receiving anesthesia/sedation once, as well as reducing the number of clinic visits. Rest assured that the accuracy of the examinations remains unaffected.

⑤ Examination and Testing by Gastrointestinal Endoscopy Specialists:

Throughout the examination and testing process, specialized physicians in gastrointestinal endoscopy will be consistently involved. We prioritize providing detailed and easy-to-understand explanations to ensure your peace of mind.

⑥ Advanced Endoscopy Equipment for Precise Gastroscopy:

We have introduced a high-performance endoscopy system that enables precise gastroscopy at a level comparable to university hospitals. You can now access advanced examinations in a nearby clinic setting.

⑦ Convenient Telephone and Web Booking:

You can make appointments via phone or through our website. To minimize waiting times, we strongly recommend making reservations whenever possible.

⑧ Equipped with a Recovery Room:

For procedures involving sedation, we have a dedicated recovery room where you can rest comfortably until fully conscious and steady on your feet.

⑨ Thorough Infection Control Measures:

All endoscopes and instruments used undergo strict sterilization and management within a controlled environment. Additionally, we utilize disposable products whenever possible to enhance infection prevention measures.

• Gastroesophageal Reflux Disease (GERD)
• Esophageal Cancer
• Barrett’s Esophagus
• Eosinophilic Esophagitis
• Esophageal Varices
• Acute Gastritis, Chronic Gastritis, Atrophic Gastritis
• Gastric Ulcers, Duodenal Ulcers
• Gastric Cancer, Gastric Polyps
• Duodenal Cancer
• Helicobacter pylori Infection
• Gastric Anisakiasis, etc.

Precautions:

• If sedation is administered, you should not drive a car, motorcycle, or bicycle on the same day. Please use public transportation or have a family member drive you when coming to the clinic or returning home.
• If you are taking any medications, make sure to bring your medication notebook or the actual medications with you.

On the examination day, please avoid wearing tight clothing or belts that constrict your body.
You can resume eating approximately one hour after the examination.

・This is an approximate amount.
・The cost may vary depending on factors such as the use of sedatives, the types of other medications used, etc.
・*Previously, we were unable to provide patients with pathological reports from pathological examinations. However, our hospital has adopted a pathological diagnosis approach where pathologists are involved in treatment decisions. As a result, pathological diagnosis reports are issued and can be provided to patients.

In addition to cash, we accept app payments, credit cards, and electronic payments.
