A colonoscopy (koe-lun-OS-kuh-pee) is an exam used to detect changes or abnormalities in the large intestine (colon) and rectum. During a colonoscopy, a long, flexible tube (colonoscope) is inserted into the rectum. A tiny video camera at the tip of the tube allows the doctor to view the inside of the entire colon.
Colonoscopy is a procedure performed to evaluate the inside of the colon or large intestine using a thin flexible tube containing a camera and a source of light at the top called a colonoscope. A colonoscope is inserted inside the rectum through the anus.
Colonoscopy is often used to look for colon polyps which can sometimes lead to cancerous cells. Colonoscopy is also performed to find out the reason behind some symptoms like:
- Blood, pus or mucus in stool
- Unexplained abdominal cramp
- Irregular bowel habit
These processes are usually safe and done efficiently by our specialist doctors of our Roy gastro and liver clinic. In some cases, medication can be given by a vein of the patient. These processes may take mostly 2-3 hours and you can go back to your home on the same day. In the case of endoscopy you must have to be an empty stomach for 4 to 5 hours to get a clear result and in case of a colonoscopy, you should only drink clear liquid for 7 to 8 hrs before the test done. There are no side effects you can face but in some cases, little discomfort can be felt. You can get the test report on the same day after 2hours of the test done.
