Gastroenterological Procedures

Gastroscopy 

Colonoscopy
A Colonoscopy is a test that allows a doctor to look directly at the whole of the large bowel (colon). In order to do this, a flexible tube (the thickness of a finger) with a light on the end of it is carefully passed through the anus into the rectum and large bowel.
To allow a clear view, your bowel needs to be completely empty and that is why it is important to follow our instructions and diet sheet carefully.
The doctor will give you medication to make you drowsy and relaxed. A nurse will be with you throughout the test. Pictures and samples (known as biopsies) may be taken and sometimes, small fleshy knobs on the lining of the bowel, which are known as polyps, can be removed.

Gastroscopy
A gastroscopy is an examination of the lining of the (swallowing tube), stomach and duodenum (first part of your upper bowel) using a flexible instrument — an endoscope — that is passed through your mouth. The endoscope is about the width of your little finger and has a light and a miniature camera at the tip. Small samples of the lining (biopsies) are sometimes taken through the endoscope.
The test lasts about for around five minutes. You will be lying on your side and the doctor will  give you medication to relax you.

Sigmoidoscopy
A sigmoidoscopy is a test that allows the doctor to look directly at the lower end of the large bowel (colon). In order to do the test a sigmoidoscope (flexible tube about the thickness of a finger with a light on end) is carefully passed though the anus into the large bowel.
