In search of a disease of the esophagus, stomach, or duodenum (exiting the stomach) Example: ulcers, hiatal hernia, cancer, infection with a fungus etc …
The examination is performed under a short general anesthetic that allows you to feel nothing and see nothing. A fine and flexible hose is introduced through the mouth which allows:
to see the inside of the stomach
to take samples for analysis if necessary
to perform certain acts (sclerosis of oesophageal varices, stenting, gastrostomy tube placement to allow feeding when it is not possible by mouth …)
The average duration of the intervention is 15 minutes.
