Gastroscopy

What is a gastroscopy?

A gastroscopy is typically a 15-minute daycase procedure that allows your doctor to examine the lining of the upper section of your digestive tract. A long, thin, flexible tube with a camera and light source on one end, called a gastroscope, is passed into your mouth and travels down your oesophagus to your stomach and duodenum, to allow your Consultant to view these areas.

A diagnostic gastroscopy is performed to investigate problems such as persistent stomach pain, heartburn, indigestion, swallowing difficulties, or unexplained blood loss from your bowel. It helps to diagnose conditions including stomach ulcers, gastro-oesophageal-reflux-disease (GORD), coeliac disease, and Barrett's Oesophagus.

A small sample of your body tissue may be taken during a gastroscopy, called a biopsy, and sent for examination under a microscope to help diagnose and assess the severity of your condition.

A gastroscopy treats oesophagus, stomach and duodenum conditions such as bleeding ulcers, a blocked or narrowed oesophagus, non-cancerous growths called polyps, or small cancerous tumours. The procedure may take longer when treating a condition.
