The colonoscope is a small camera attached to a flexible tube. For the procedure, you will lie on your left side with your knees drawn up towards your stomach. During the procedure your position may be changed to aid in the movement of the colonoscope.
After you have received a sedative and pain reliever, the colonoscope is inserted through the anus and gently advanced to the sigmoid colon. In some cases a nurse may apply pressure to the abdomen to help the progress of the camera. Air will be inserted through the scope to provide a better view. Suction within the camera may be used to remove secretions.
Tissue samples and polyp removal may be taken during the procedure. These samples are then sent to the laboratory for testing and these results will be available 7-10 days after your procedure.
A flexible sigmoidoscopy takes approximately 10-15 minutes but you will be at your appointment for up to 2 hours while we monitor you after your procedure.
