A colonoscopy is a telescope test to examine the colon, the part of your bowel which is can grow polyps, which can in time turn into bowel cancers.  With a colonoscopy, most polyps can be removed during the procedure.

What to expect

The worst part of a colonoscopy is usually the bowel preparation.  So that the inside of the bowel can be seen, you will be given strong laxatives to clear the bowel.  This is done the day before your procedure so you may need to take the afternoon before off work.

You will be admitted to the hospital on the day of your colonoscopy.  You will be given medication through a drip in your arm to sedate you and make the procedure more comfortable.  After your procedure you will wake up in the recovery area of the hospital where specialized recovery nurses will look after you and ensure you recover from your sedation safely.  After you have recovered you will be given something to eat and drink and allowed to leave.  Dr Hamer will let you know what was found on the day.  

Colonoscopy is a very effective test and will detect over 95% of adenomas or polyps that may be in the bowel.  It is a very safe test.  The risk of the colonoscope perforating the bowel is around 1/1000.  If this does occur, you may need an emergency operation to repair this.  If a polyp is removed a bleed can occur 5-7 days after your procedure.  Rarely a blood transfusion may be required in this situation.

After discharge

After discharge, the effects of the sedation can take 24 hours to wear off.  You need to avoid driving, operating machinery, drinking alcohol, climbing ladders, make any important or legal decisions.  You should have a responsible adult with you for this 24hr period. 

Problems:  Complications are very unusual.  If you do have any problems you have multiple ways of accessing help.  During office hours you can contact Dr Hamer's rooms or your GP.  For more pressing problems or after hours you can also contact the emergency department at the hospital.
