Gastroscopy or upper gastrointestinal endoscopy, is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract up to the duodenum. It is a minimally invasive procedure, however, a sore throat is common.
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), and treat conditions such as bleeding ulcers, a blockage in the oesophagus, non-cancerous growths (polyps) or small cancerous tumours.
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.
