Gastroscopy – fibre-optic instruments (various endoscopes) and thin impedance- (resistance-) measuring devices are used for the instrumental examination of the stomach.
These have to be swallowed by the patient, which is more unpleasant than painful.
However, with close cooperation with the doctor and the specialist nurse and a little self-discipline, it does not put too much strain on patients.
The stomach-endoscopy (gastroscopy) involves inflating the stomach with air so that, on the stretched stomach-wall, the folds of the lining are smoothed out, making the entire surface of the lining visible.
The patient then feels as if they were bloated and needed to burp. Taking a tissue sample (biopsy) is painless.
The examination takes a few minutes; afterwards, you must not eat or drink for at least half an hour (because of the anaesthetic liquid, the patient could easily swallow the wrong way).
