A gastroscopy examines the esophagus, stomach, and upper part of the duodenum. The examination usually takes less than ten minutes. It is common for patients to receive medication to help them sleep (sedation) and therefore hardly notice anything during the examination (“gentle gastroscopy”). Many patients take advantage of this option (of course you can also do without it).
During the examination, the doctor takes photographs of all areas examined. These photos are then usually part of the report. Two double biopsies (removal of tissue samples) are routinely taken in the stomach (in the antrum and corpus ventriculi). If necessary, additional conspicuous areas are biopsied. The patient does not feel the biopsy being taken, but it often provides informative information for the diagnosis. In many cases, the cause of an inflammation of the stomach (gastritis) can only be clarified by means of a biopsy. The result of the biopsy is available a few days after the examination.
Risks of the gastroscopy:
Before each gastroscopy, a detailed explanation about the procedure and the risks is required in a timely manner.
Preparation for gastroscopy
For the examination, the patient must be fasting, i.e. no solid food for at least six hours and no liquids for at least three hours. Immediately before the examination, the throat can be numbed with a xylocaine pump spray. In addition, the patient has access to the application of the sedation (propofol is usually used for this).

After the gastroscopy
When using sedation with propofol, the patient has to sleep for about an hour after the examination. Drinking or eating is also only allowed/possible when the throat anesthesia has worn off and the sedation has worn off completely (at least one hour). After receiving sedation, no vehicle should be driven for 24 hours. It is therefore advisable to be picked up or to use public transport
