What is it?
This is the examination of the inner lining of the gullet (oesophagus), stomach and the first part of the small bowel (duodenum).
The examination takes 5- 10 minutes and most patients tolerate this procedure with a local anaesthetic spray which makes the mouth and throat numb, however, sedation is available if necessary.
