Colonoscopy
What is colonoscopy?
Colonoscopy is an endoscopic test to examine the mucosa (inner lining) of large intestine which is also called colon. The examination involves introducing a camera attached to a tube to be inserted in the back passage and then proceeding to look at the mucosa. It is usually done by a Physician who is trained in Endoscopy/Gastroenterology.
When should it be done?
1. Blood in stool or bleeding from back passage
2. Change in bowel habits
3. To investigate the cause of low Haemoglobin (Anaemia)
4. To investigate and obtain biopsies in case another test (eg. CT scan) suggests any abnormality in Colon
5. To look for Cancer or polyps in the colon.
Does one need any preparation before Colonoscopy?
Colonoscopy requires a special preparation and for this special instructions are given. Some medications like blood thinners may need to be stopped before the test. Also a special diet and medication to clear the colon is necessary so that it can be examined appropriately. In case you have problems during the preparation it is important for the doctor to know.
Undergoing a Colonoscopy:
Sometimes the examination may be incomplete as the preparation may be poor or another reason which shall be discussed. In such cases a repeat colonoscopy or the next best diagnostic modality may be recommended.
