What is Colonoscopy?

Colonoscopy is a diagnostic procedure to examine your colon with the endoscope inserting through anus, rectum, advancing into colon, and finally caecum, or terminal ileum. If any abnormality or polyp is detected, biopsy or polypectomy will also be done during the procedure.

Why Endoscopy Examination is Important

  • Early detection and removal of polyps reduce the chance of development of colorectal cancer.

WHO NEEDS A COLONOSCOPY?

  • Aged 50 or above
  • With family history of colon cancer

    • Change in frequency of bowel habit
    • Blood in stool
    • Incomplete evacuation feeling
    • Persistent abdominal pain
The Procedure
  • You will be instructed to position yourself in a proper way. Sedation medication will be given for sleep induction.

  • If polyp is found, it will usually be removed by dedicated equipment.
How Long Does it Take
  • The procedure normally takes about 30 minutes, but varies with actual circumstances.
  • Taking the recovery time for sedative worn-off into account, please prepare a 2-3 hours stay at the Centre.

  • Before the procedure day
    • Consume low residue diet 3 days before the procedure; avoid high-fiber food, e.g. fruits, vegetables, high-grained carbohydrates.
    • Consume fluid diet 1 day before the procedure. BEWARE: milk is NOT allowed.

Points to Note
  • Complications including delayed bleeding or perforation during the procedure is uncommon.
  • Client may experience mild swelling and affliction, and CO2 insufflation will be carried out to minimize the discomfort, as the substance is proved to be rapidly cleared from colon by passive absorption.
  • Colonic distention and pain can be significantly reduced with CO2 insufflation, compared to air insufflation, without any additional adverse reactions (1, 2).
