What can an upper GI endoscopy find?
An upper GI endoscopy gives a direct, magnified view of the lining of the food pipe, stomach and the first part of the small intestine. It is used to look for:
- Reflux oesophagitis and GERD: inflammation of the food pipe from acid reflux, and changes such as Barrett's oesophagus.
- Gastritis and peptic ulcers: including ulcers caused by H. pylori infection or painkillers.
- Bleeding sources: ulcers, erosions or varices (swollen veins) in patients with liver disease.
- Swallowing problems: narrowing (strictures), rings, webs or motility problems that need further tests.
- Coeliac disease: biopsies from the duodenum help confirm the diagnosis.
- Polyps and growths: small lesions can be sampled, and early lesions characterised with image-enhanced endoscopy.
