During a Gastroscopy your endoscopist passes a long flexible tube containing a camera and a light through your mouth, over the back of your tongue, down your oesophagus (gullet), a deflated balloon is inserted into the narrowed area. It is then inflated with water which stretches the stricture (narrowing). Your endoscopist may want to take a look further into your stomach and duodenum (first part of small bowel) to view the lining of these organs.
