Gastroscopy

Why do l need a gastroscopy?

A gastroscopy is often recommended when you have symptoms of upperdigestive problems. These may include problems such as indigestion, pain in the upper abdomen or vomiting of blood stained material among other symptoms. Sometimes a gastroscopy may be done more than once, to make sure that the lining of the digestive tract has healed after the treatment. 

What can a gastroscopy?

A gastroscopy can show many conditions that affect the digestive system, for example:
- Reflux of acid from the stomach up into the gullet
- Oesophagitis, or inflammationof the lining of the gullet
- Ulcers on the lining of the gullet, the stomach or the duidnum
- Cancer of the stomach
Sometimes your specialist will take a small sample of the tissue lining the walls of the digestive tract. This is called a biopsy. The biopsy sample will be sent to a pathology laboratory where it can be examined under the microscope to look for possible infection or abnormal cells. Recently, the bacteria helicobacter pylori has been shown to cause duidenal ulcers in some people. If this is detected, a specific treatment can be given to remove it.

Is a gastroscopy painful?

You should feel no pain when you are having a gastroscopy. A local anaesthetic to numb your throat will be used, either as a spray or a gargle, and you will be given a strong, short acting sedative anaesthetic. You will feel drowsy during the test, and may not remember much about it afterwards.

Because of the procedure is done under local anaesthetic, the risks of heart or lung complications is also extremely rare - less than 0.05%
