Description

A colonoscopy is a procedure that examines the large intestine (colon) and the rectum for any unusual changes or abnormalities. This test is performed to screen for polyps and possible indicators of colon cancer. During a colonoscopy, sedation is advised. A moderate sedative is sometimes given as a tablet. In certain situations, the sedative is mixed with intravenous pain medication to reduce discomfort. You will be laying on your side on the exam table, normally with your knees drawn near your chest, for the examination. A colonoscope will be inserted into your rectum by the doctor. The colonoscope has a flexible tube with a tiny camera attached to it. The camera transmits images to an external monitor, allowing your doctor to examine the inside of your colon. To improve the view, air will be injected through the scope. To remove fluid or stool, suction can be utilized. Using microscopic biopsy forceps introduced through the scope, tissue samples can be obtained. Electrocautery snares can be used to remove polyps, and photos can be taken.
