A gastroscopy, also known as an oesophago- gastro-duodenoscopy (OGD), an examination of your oesophagus (gullet), stomach and the first part of your small bowel called the duodenum. This test is a very accurate way of looking at the lining of your upper digestive tract, and to establish whether there is any disease present. The instrument used in this investigation is called a gastroscope. It is a flexible tube and has a diameter approximately that of a little finger. Tests will also be done to identify the presence of H.pylori, a bacteria which has been linked to upper gastrointestinal disease.
Some of the indications for a gastroscopy include unexplained anemia, intestinal bleeding, abdominal pain, heartburn, persistent vomiting and difficulty swallowing. A gastroscopy can also be used to treat a variety of conditions including intestinal bleeding, strictures and removal of foreign bodies.
