Colonoscopy Procedure
A nurse places place a catheter in an arm or hand vein so the physician is able to give you medication to keep you comfortable and lightly sedated. You are then positioned on your left side to allow the physician to insert a thin flexible tube, (colonoscope) into your colon.
Colonoscope
The colonoscope bends to allow the physician to move it around the curves of your colon and it puffs air into the colon to allow better visualization. The exam usually takes about 30 minutes.
Biopsy
During the exam, the physician may take a piece of tissue, called a biopsy, or remove a polyp with tiny instruments inserted through the scope. These procedures do not cause you any more discomfort. All tissue specimens are sent to a lab for inspection by a pathologist. Your physician may also take a picture of the exam findings for documentation in your chart.
Safety
Colonoscopy is generally very safe, but as with any invasive procedure, complications (including perforation, bleeding, infection and excessive sedation) have been known to occur. You are able to address any questions or concerns with your physician prior to the exam.
Post Exam
Following your exam you remain in the recovery area until you are alert. Your physician then explains what was seen during the exam and discusses your plan of care. A nurse provides you with written instructions and makes a follow-up call to you the next day.
