Colonoscopy

Centre for GI Health Specialists are experts in Colonoscopy. The procedure is performed at accredited hospitals to ensure that you receive excellent care, have an anaesthetist present and are supported by qualified medical staff.

Colonoscopy allows examination of the lining of the colon (large bowel) using a thin flexible tube with a video camera, lens and light source at its end called a colonoscope. The colonoscope is advanced slowly from the rectum, around the colon examining the lining for polyps, tumours, areas of inflammation and other diseases.

Why is it needed?

If you have had the following symptoms, a colonoscopy may be required. 

• Rectal bleeding

• Iron deficiency (anaemia)

• Abdominal Pain and any changes in bowel habits

• Family history (including a family member with colon cancer or polyps).

• Clarification of barium enema or CT scan findings

• Positive Faecal Occult Test (FOBT)

• Previous bowel polyps or cancer

• Surveillance of inflammatory bowel disease.

Risks associated with a colonoscopy

Adverse reactions are not expected at colonoscopy, however, you should be aware of possible complications that may arise from the investigation

• Anaesthetic risk - reaction to the sedatives or anaesthetic used, complications from heart or lung disease, localised irritation of the vein area where injected may cause a tender lump lasting for several weeks.  Applying heat packs or hot, moist towels may help relieve discomfort.

• Perforation or tear through the bowel wall that could require surgery.

• Bleeding from the site of a biopsy or polyp removal.

Although complications after colonoscopy are uncommon, it is important for you to recognise early signs of any possible complications:

• abdominal pain,

• fevers or chills,

• rectal bleeding (more than half a cup).

If you are experiencing any problems contact your doctor or the nearest hospital emergency department for assistance.
