What happens during an examination?
The endoscope 1) is inserted through the mouth or nose then into the oesophagus 2) and finally into the duodenum 4) .Through insufflation of air, the stomach will expand; now the doctor has the possibility to see the mucosa, even small mutations are recognisable.
The stomach has to be completely clean, that means the patient should not eat for one day before the examination.
For making the insertion of the scope easier, the nasal mucosa will be atomised with anaesthetic. If it’s requested or necessary the patient will receive a sedative or “sleep inducing” medicament. The use of ultra thin gastroscopes with a calibre of only 5,9mm makes the examination more agreeable for the patient as they can be inserted through the nose.
The examination is done as an outpatient procedure and will in normal cases only take some minutes. Afterwards, the patient is able to perform normal daily activities.
Only if a sedative medicament was given, the patient should take a short rest.
Extraction of tissue specimen / therapy
During the examination it’s possible to take small mucosa samples with biopsy forceps. These samples will for example be tested for the existence of helicobacter pylori. Helicobacter pylori is a strain of bacteria in the stomach which can cause gastritis which, if left untreated can lead to the formation of a stomach ulcer.
