Gastroscopy

This study is characterized by even 98-100 percent. diagnostic accuracy, and is therefore necessary to establish an accurate diagnosis, prescribe the most effective treatment and achieve the best treatment results. During gastroscopy, even the smallest changes in the esophagus, stomach, and duodenum can be diagnosed. If necessary, small pieces of the organ (biopsy) can be taken during the examination for microscopic histological examination.

At the Nefridas clinic, gastroscopy is performed only for persons over 18 years of age.

When is this test recommended:

• In case of pains or unpleasant sensations in the upper part of the abdomen, when the previously prescribed treatment does not help;
• The examination is also recommended for those who complain of disturbed and painful swallowing;
• In case of recurrent and ongoing gastroesophageal reflux disease; Unexplained nausea and vomiting;
• For active and chronic bleeding;
• For iron deficiency;
• When pathological formations are diagnosed by other radiological tests.

During gastroscopy, it is possible to diagnose both benign (erosions of the esophagus, erosions and ulcers of the stomach and duodenum, various inflammatory changes of the gastric mucosa, etc.) and malignant diseases.

Preparation for the study

• This test requires special preparation. Here is a short guide on how to prepare for the procedure so that the examination goes smoothly.
• Before the test, it is recommended not to eat anything for at least 6-8 hours before the procedure, and not to drink liquids for 2-3 hours.
• In the morning, you can brush your teeth and rinse your mouth.
• If you are taking blood pressure medication or other medications, you can take them in the morning with a small amount of water.
• When preparing for a gastroscopy, be sure to consult the referring doctor about the medications you are taking. In order to ensure the most accurate diagnosis and avoid the risk of complications, he may recommend stopping the use of certain medications.
• About 2 hours before the test, it is recommended not to smoke, because the color of the gastric mucosa may change.
• It is advised to wear comfortable clothes during the examination.

The course of the procedure

Before performing a gastroscopy, the patient is introduced to the course of the examination, informed about possible unpleasant sensations and actions that can be taken to minimize them.

The procedure is performed by an endoscopist doctor, together with a nurse assisting him.

Before the procedure, you will be asked to remove dental plaques (if you have them) and remove your glasses.

Gastroscopy is performed under local anesthesia of the pharynx – lidocaine aerosol is sprayed into the mouth before the procedure. If you have ever had an allergic reaction to lidocaine, be sure to tell your doctor or nurse.

The patient is asked to lie on his left side and is explained how to breathe correctly during the examination. Listening to what the nurse or doctor has to say makes it easier to control yourself, which reduces unpleasant sensations. After the patient bites a special mouthpiece, the endoscopist inserts the endoscope through the throat into the esophagus, stomach and duodenum. During the examination, air is blown in order to inflate the broken beams and make the examination informative. To make the process of inserting the endoscope smoother, the doctor may ask the patient to swallow.

The procedure performed for the purpose of the study takes 5-15 minutes. If the procedure is performed for the purpose of treatment, it may last longer.
