A colonoscopy is a procedure that allows the physician to visualize the interior areas of the rectum and colon. A colonoscopy is the best procedure used to discover and treat abnormal growths within the colon. Complications are rare when the procedure is completed by a specially trained physician.
Identification
A colonoscopy is an outpatient medical procedure that evaluates the inside of the colon or large bowel. It is common for a gastroenterologist to perform a colonoscopy, as this is a specialized procedure. The procedure involves inserting a tube with a camera through the anus and into the colon. The physician is able to view the entire procedure on a monitor.
Reason for Procedure
A colonoscopy evaluates symptoms of abdominal pain, rectal bleeding and changes in the bowel. The procedure is also used to check for cancer or polyps growths in the colon. A periodic colonoscopy is recommended for people with a family history of colon cancer.
Preparation
The colon must be completely clean prior to the colonoscopy procedure. A special cleansing drink may be prescribed. The physician will give detailed instructions for the colonoscopy preparation as it may vary by hospital. Not following the preparation instructions may result in having the test repeated at a later time.
Exam Procedure
A colonoscopy is 15-60 minutes in length, depending on how visible the colon is at the time of the procedure. The procedure entails inserting a colonscope into the anus, through the rectum and into the colon. The scope is an instrument that is approximately half inch in diameter and flexible. The colonscope allows access for a camera and tissue examining tools. Tissue may be taken for analysis or polyps removed during the process. During the procedure you will be given a sedative to relax and you may feel some mild cramping.
After Treatment
You will stay in a recovery room for 1-2 hours following the procedure. There may be symptoms of cramping or the feeling of passing gas. You may resume eating a normal diet following the procedure unless notified otherwise by the physician. There may be rectal bleeding if tissue samples were taken or a polyp was removed. Do not drive or operate large machinery for 24 hours following the procedure as the sedative may make you drowsy or impair judgment.
