The Procedures


Colonoscopy is a visual examination of the lining of your colon (Large Intestine). This procedure is used for diagnosing and treating a variety of problems encountered in the colon. It is performed using an instrument called a colonoscope, which is a flexible tube that is about the thickness of a finger. It is inserted via the rectum into the colon  and allows the doctor to carefully examine the lining of the bowel.

Colonoscopy is used to look for a variety of conditions. These include colon cancer and colon polyps. Colon polyps are small growths on the lining of the colon that can sometimes be cancerous or may grow to be cancerous. A colonoscopy may also be performed in order to find the cause of signs and symptoms including

  • Bleeding from the rectum
  • Blood in the stools
  • Pus or mucus in the stools
  • Unexplained abdominal pain
  • Changes in bowel habits such as unexplained and long-lasting diarrhoea



A colonoscopy can be undertaken to locate or remove polyps. These are small growths on the lining of the bowel. They are usually benign but occasionally can contain a small area of cancer.

Removal of a polyp is called a polypectomy. This is achieved by passing a wire loop through the colonoscope and snaring the base of the polyp, which is then severed from its attachment to the bowel wall by means of an electric current. This current  cannot be felt and causes no pain to the patient.

Early detection and removal of polyps prevents them from becoming malignant, and is therefore an important means of protection form bowel cancer.



Gastroscopy is a procedure that enables the Doctor to see inside your oesophagus, stomach and intestines. The Doctor can directly visualise these areas and can diagnose ulcers, cancer and irritation that may be causing pain or other symptoms. If the Doctor suspects you may have Coeliac Disease he is able to take a small biopsy from your duodenum (Small Intestine) that will help in the diagnosis. It is also possible to dilate narrow parts of the gullet that may be causing swallowing problems.
