What Is Colonoscopy?

Colonoscopy is a procedure that allows your gastroenterologist to examine the inside of your large intestine (colon and rectum) using a colonoscope. The colonoscope is a thin, flexible tube that has a small camera at the end. Colonoscopy is the most accurate and effective screening test for colorectal cancer.

Why Is Getting a Colonoscopy So Important in Singapore?

Colorectal cancer is the #1 commonly diagnosed cancer among Singaporean population. It is also 1 of the top 3 leading causes of cancer deaths in Singapore.

Colorectal cancer generally starts from small benign growths (polyps) that develop in the lining of the colon. It often develops silently, without displaying any symptoms.

A colonoscopy detects benign polyps and allows them to be removed before they turn cancerous.

A colonoscopy is the most effective screening method to prevent and detect colorectal cancer early, when the survival rate is close to 90%.

  • Colonoscopies are accurate
  • Colon cancer can happen to anyone

    Frequently Asked Questions

    Most colonoscopes are performed under sedation, which results in minimal discomfort during the procedure.

    A colonoscopy typically takes 20-30 minutes.

    A colonoscopy is a relatively safe procedure  with low risks of complications. The 2 major risks associated with a colonoscopy are perforation and bleeding at the site of biopsy.  However, these complications are very rare, occurring 1 in 1000 cases.

    A successful colonoscopy largely depends on preparation. Your colon needs to be clean and empty to enable a clear view . You will be given laxatives either the evening before or on the same day of the procedure. You will be given detailed instructions to help you prepare for your colonoscopy.

    Please inform the doctor on what medications or supplements (if any) you take on a daily basis, especially blood thinners eg aspirin. The doctor will let you know if you need to avoid or reschedule certain medicines before your colonoscopy.

    A colonoscopy is typically performed as a day surgery. You may go home the same day after a short period of observation.

    If you were given a sedative, you should have someone accompany you on your way home, as the medication affects coordination and judgement. Some patients may experience mild abdominal discomfort or bloating after the procedure, but most should resolve by the next day.
