Colonoscopy

What is colonoscopy?

Colonoscopy is a diagnostic test that uses a thin, flexible tube with a light and camera that allows doctors to examine the lining of your large intestine. The gastroenterologist inserts the tube — colonoscope — in the anus and slowly advances it through the entire length of the rectum and colon. 

The gastroenterologists at Capitol GI perform colonoscopies as a screening measure for conditions and to diagnose and treat gastrointestinal conditions. 

When do I need a colonoscopy?

Your gastroenterologist explains when you need a colonoscopy. They may recommend the test if you have abdominal pain, blood in your stool, or a change in bowel habits, and other less invasive tests fail to indicate the cause of your symptoms.

You may also need a colonoscopy if you have a chronic gastrointestinal condition like inflammatory bowel disease (IBD) that needs ongoing monitoring. 

The colonoscopy is also the gold-standard colon cancer screening test. Colon cancer most often develops from noncancerous colon polyps. Finding and removing polyps may reduce your risk of colon cancer. 

What happens during prep for a colonoscopy?

You need a completely clean colon in order to get a colonoscopy and must undergo bowel prep to get ready for the procedure. Bowel prep usually involves diet modifications and the use of a laxative that removes all stool and debris from the colon.

Your provider at Capitol GI gives you specific instructions on the steps you need to take to prepare for your colonoscopy. Failure to follow your bowel prep program may delay your colonoscopy. 

What can I expect during a colonoscopy?

Your gastroenterologist reviews the details of your colonoscopy at your consultation, so you know what to expect. After changing into a medical gown, you lie on your side on the exam table. 

Your provider places an intravenous (IV) line in your arm and gives you medicine that helps you relax during the test. Then, they insert the colonoscope into your anus and slowly advance it through your colon, closely examining the lining of the intestinal tract.

They remove any polyps and take samples of abnormal tissue during the procedure. 

You go to the recovery room following your colonoscopy. Your gastroenterologist discusses the results of your test with you and then discharges you home. You must arrange to have someone drive you home following your colonoscopy and take it easy the rest of the day.
