Colonoscopy allows the Gastroenterologist to examine the entire large intestine (colon) of a patient under sedation. A colonoscope, which is a long flexible tube equipped with a miniature video camera at its tip, is inserted through the anus. This allows the Gastroenterologist to see inside the intestine, take tissue samples (biopsies), and if necessary remove polyps.
- This procedure is performed to investigate conditions such as:
- Rectal bleeding
- Colonic Polyps
- Diverticulosis and Diverticulitis
- Irritable Bowel Syndrome
- Inflammatory Bowel Disease
- Crohn’s Disease
- Ulcerative Colitis
- Other types of Colitis
- Colon Cancer
The surgical procedures provided at the Centre for Digestive Diseases do not require a general anaesthetic as intravenous sedation is given for these procedures. The Sedationist will insert a small needle into a vein in the back of your hand or in your arm through which the sedative will be injected. The injection may cause a local reaction. Bruising under the skin may occur, but should not cause permanent damage and is usually not painful. If you are having a gastroscopy procedure, your throat may be sprayed with an anaesthetic agent and may feel numb for a short time.
The procedures described above are considered to be safe. However, temporary discomfort or pain may occur following introduction of air into the stomach or bowel. Major complications are rare but can occur. These complications include perforation (puncture) of the oesophagus, stomach, duodenum, small bowel or colon. Haemorrhage (bleeding) following removal of polyps, infection, cardiac or respiratory arrest related to sedation / anaesthesia. If you wish to discuss the potential risks or any issues regarding your procedure(s) in more detail, please ask to speak with the Gastroenterologist.
