Gastroscopy
A gastroscopy is a procedure where a thin, flexible tube called an endoscope is used to look inside the oesophagus (gullet), stomach and first part of the small intestine (duodenum).
The endoscope has a light and a camera at one end. The camera sends images of the inside of your oesophagus, stomach and duodenum to a monitor.
Why a gastroscopy may be used
A gastroscopy can be used to:- Investigate problems such as difficulty swallowing (dysphagia) or persistent abdominal (tummy) pain
- Diagnose conditions such as stomach ulcers or gastro-oesophageal reflux disease (GORD)
- Treat conditions such as bleeding ulcers, a blockage in the oesophagus, non-cancerous growths (polyps) or small cancerous tumours
A gastroscopy used to check symptoms or confirm a diagnosis is known as a diagnostic gastroscopy. A gastroscopy used to treat a condition is known as a therapeutic gastroscopy.
Why is a gastroscopy done?A gastroscopy, also known as an upper gastrointestinal endoscopy or just upper endoscopy, is usually done to investigate the cause of symptoms such as heartburn, abdominal pain, difficulty swallowing, vomiting or bleeding from the digestive tract, and to make or confirm a diagnosis.
Conditions can also sometimes be treated during gastroscopy — for example:
- Polyps can be removed
- Enlarged veins (varices) in the oesophagus (food pipe) can be treated to stop and prevent bleeding
- A narrowed oesophagus can be widened and foreign objects (such as objects accidently swallowed by children) can be removed.
