You can refuse it. The whole process does not take a long time. With the intervention through the oral cavity, the duration will be about 10 minutes, and through the nasal cavity - much less. Therefore, people of advanced age are recommended to carry out surgery through the nose, because there is no nausea, and the procedure is much easier than through the mouth.

    Clinical examination of patients with impaired functions of the gastrointestinal tract, when using the methods of fibrogastroduodenoscopy and esophagogastroduodenoscopy, complications are possible. But they do not carry a significant danger, and the likelihood of such a result is not high. Yet it is necessary to know what is the difference between them in order to conduct timely intervention.

    EGD is a rather complicated procedure, therefore after it unpleasant symptoms lasting several hours are possible. These can be:

    • violation of the integrity of the walls of the esophagus or stomach;
    • feeling of nausea, vomiting, lasting some time after the operation;
    • discomfort in the abdomen from bloating, tingling, heaviness;
    • pain in the lower abdomen;
    • the introduction of any infection into the body;
    • damage to blood vessels and bleeding.

    The patient may have more severe symptoms, the presence of which provides for immediate access to a medical specialist. Such signs:

    • vomiting with blood veins or the presence of blood clots;
    • increased body temperature;
    • diarrhea with a feces of black color;
    • strong and intolerable pain in the abdominal region( rezi, tingling);
    • can cause dysbiosis and other diseases when infectious lesions occur.

    In addition to fibrogastroduodenoscopy, EGDS is also associated with some complications that may appear after diagnosis. Deterioration of well-being and prolonged painful sensations can contribute to the development of negative consequences. In this case, the intervention of a medical specialist is indispensable. But serious complications are rare:

    • perforation - when it occurs, it is impossible to do without surgical intervention, as it can cause the death of the patient;
    • internal bleeding affecting the digestive system.

    Fibrogastroduodenoscopy and esogastroduodenoscopy are indispensable diagnostic studies in the detection of pathological processes of the gastrointestinal tract. Therefore, for the best result, you need to know their features, including special attention should be given to the difference between them.
