Colonoscopy
A colonoscopy is an examination of the lining of the large bowel using a thin flexible camera. It is used to investigate bowel symptoms, to screen for bowel cancer and to remove polyps.
Why a colonoscopy may be advised
- Bleeding from the back passage or blood in the stool
- A persistent change in bowel habit
- Unexplained abdominal pain, weight loss or anaemia
- Screening or surveillance for colorectal cancer, including a family history
- Follow-up of inflammatory bowel disease or previously removed polyps
Preparation
The bowel must be empty for the camera to see the lining clearly. You will be given written instructions about diet and a bowel preparation to drink beforehand, and told which of your medicines to pause.
On the day
The procedure is usually done with sedation and takes around twenty to forty minutes. Polyps can often be removed at the same time and sent for testing. You will need someone to drive you home afterwards.
Results
Findings are discussed with you after the procedure, and any laboratory results are followed up at a review appointment.
Arrange a consultation
The rooms are at the Wits Donald Gordon Medical Centre, Parktown, Johannesburg.
