Colonoscopy
A colonoscopy is a procedure used to examine the large bowel (colon) using a thin, flexible instrument called a colonoscope.
The colonoscope is equipped with a video camera that allows specialists to view the inside of the colon in real time and to:
- Take biopsies (small tissue samples) for further examination
- Remove polyps (abnormal growths) that could potentially become cancerous
The procedure typically takes 20 to 30 minutes.
Why is a Colonoscopy Performed?
Investigating symptoms such as diarrhoea, abdominal pain, and rectal bleeding
Screening for bowel cancer, particularly for individuals with a family history of the disease
Monitoring and diagnosing conditions such as Inflammatory Bowel Disease (IBD), Crohn’s disease, and ulcerative colitis.
While alternative tests like barium enemas and virtual CT colonoscopies exist, they are less sensitive and do not allow for biopsies or polyp removal.
Comfort and Sedation
Sedation ensures that you are completely relaxed and unaware during the procedure, and you do not experience pain or discomfort while the colonoscope is in use. After the procedure temporary bloating or wind pain may occur due to the gas used to inflate the colon. This typically resolves quickly.
Preparing for Your Colonoscopy
A clear bowel is essential for a successful colonoscopy. Patients will need to:
- Closely follow specific bowel preparation instructions provided by your admitting doctor before the procedure
- Drink clear fluids leading up to the appointment
- Stop consuming fluids two hours before admission
- Adjust medications such as blood thinners and diabetes treatments, if required and as directed by your admitting doctor.
After Your Colonoscopy
Following the procedure, you will be:
- Moved to a recovery area where you will be closely monitored
- Provided with light refreshments before discharge
- Given your results and any necessary follow-up arrangements.
You cannot drive for 24 hours after being medically sedated. A responsible adult must pick you up from hospital and stay with you until the following day.
