Endoscopy and Colonoscopy Q & A

What happens during an endoscopy?

An endoscopy is a diagnostic procedure that uses a long, flexible instrument called an endoscope that's inserted down your throat to evaluate your upper gastrointestinal tract, including the esophagus, duodenum and stomach. You'll be sedated during the procedure, and your throat will be numbed so you won't have to worry about gagging. Once the scope is inserted into you esophagus, a tiny camera attached to the end of the scope will be used to transmit images back to a monitor where they can be viewed. If an abnormal area is identified, small tissue samples can be removed (biopsies) for evaluation under a microscope. Some procedures can also be performed using special instruments designed to be used with an endoscope. Endoscopies are often performed to look for signs of ulcers and to evaluate the effects of GERD (gastroesophageal reflux disease), as well as to diagnose other symptoms.

What happens during a colonoscopy?

A colonoscopy is similar to an endoscopy except it's used to evaluate the inside of the colon (large intestine) and rectum. During a colonoscopy, you'll be sedated so you can sleep throughout the procedure. A small amount of air will be pumped into your intestine to expand it so the lining can be seen more clearly. A tiny camera at the end of the colonoscope transmits images to a screen so they can be easily viewed. If a polyp or other abnormal tissue is identified, it can be removed for evaluation in a lab. While most colonic polyps are benign (non-cancerous), some are cancerous, and colonoscopy is the best way to detect colon cancer in its earliest and most treatable stages.

Can I drive myself home?

No, both procedures require sedation, so you'll need to arrange to have someone else drive you home afterward.
