Q: What happens during a colonoscopy?
Prior to the procedure, patients will receive an IV sedative to help them to relax. Patients will then lie on their side on an exam table. Once the sedative starts working, the colonoscope will be guided through the anus and gently moved through the rectum and colon. This special device takes pictures of the inside of the intestinal tract. These images will be displayed on a monitor so the doctor can see the large intestine. If polyps are found, they can be removed with instruments designed to be inserted through the scope. Biopsies, or tissue samples, are taken if necessary and then evaluated in the lab. Once the procedure is finished, the colonoscope will be withdrawn and the patient is taken to a recovery area.
