GastroscopyThis procedure involves an endoscope – a long, thin flexible tube with a ‘video camera’ at the tip – being passed through the mouth into the oesophagus, stomach and first part of the small bowel.

It allows the doctor to inspect these areas and perform specialised procedures such as biopsies. Gastroscopy is usually performed to evaluate symptoms of indigestion, reflux, upper abdominal pain, nausea, vomiting or difficulty swallowing.

It is also the best test for both finding and treating any bleeding from the upper gastrointestinal (GI) tract.  Gastroscopy is also used to treat conditions of the upper GI tract, for example, your doctor might stretch a narrowed area, or remove polyps from the upper GI tract.
