What is a Colonoscopy?
Colonoscopy is a procedure that enables your physician to observe your large intestine, from the rectum, through the colon to the lower end of the small intestine utilizing a small instrument called an “colonoscope.” This procedure is utilized to check for early signs of cancer, diagnose the causes of changes or abnormalities in bowel habits or assess other digestive issues of the large intestine such as inflammation of tissue, abnormal growths, ulcers, and rectal bleeding.
What Can You Expect?
During the procedure you will lie on your left side upon an examining table. You will likely receive a pain medication and a mild sedative to help you feel comfortable and to relax during the exam.

The flexible colonoscope will transmis images of the colon to a computer so your 7 Hill GI specialist can carefully examine the tissue lining of the colon. The colonoscope is used to blow air into your colon to inflate the space for improved visibility. Occasionally, your doctor may engage your assistance by asking you to change move to a help position the colonoscope for better imaging views.
Abnormalities found can be removed in part or whole using extremely small instruments inserted through the scope. That tissue sample (biopsy) is collected for testing.Bleeding in the colon can be stopped using a laser, heater probe, or electrical probe, or via special medicines injected through the scope.
