Diagnostic gastroscopy


Gastroscopy is a diagnostic test that permits to visualise the upper digestive tract (esophagus, stomach and duodenum) to detect potential problems or diseases, or to perform therapeutic procedures.


Gastroscopy is performed with an instrument called endoscope, a flexible tube with a light and a camera at the end.

The endoscope is guided into the stomach and duodenum for possible anomalies. Patients can also take the opportunity to take tissue samples (biopsy).

It is a painless test, although a relaxation medication is usually provided. The examination should not take more than 5 minutes and it is done with sedation.


The stomach must be completely empty so patients must not eat since the night before.  Do not  smoke before gastroscopy.

Also, if they have any chronic illness or regularly take medications, especially anticoagulants, they should inform the surgeon before surgery.


A few minutes later, patients can return to their activities and eat or drink normally.
