What is a Colonoscopy?
Colonoscopy is a procedure in which the large intestine and the colon are examined. The examination is carried out by using an endoscopic instrument known as a colonoscope. The instrument is a long thin tube with a tiny camera attached to it. During colonoscopy your doctor can diagnose and treat diseases like ulcers, abnormal growths, inflamed tissues and so on, without the need for a major operation.
How to be prepared for a Colonoscopy?
Inform the doctor about your medical conditions that require attention, such as:
Heart condition
Lung condition
Diabetes
Allergy to any medication
Pregnancy
Antibiotics may be required in the following conditions:
If the patient has an artificial heart valve
If the patient requires antibiotics before a surgical or a dental procedure for certain medical reasons
The doctor may give instructions on diet and fluid restrictions. You may be required to take laxatives orally to clean out the colon.
Enemas are usually given to clean out your bowels.
How is a Colonoscopy performed?
The patient is asked to lie on the side on the examining table. A colonoscope is inserted from the anus, through the rectum and moved to the large intestine. The colonoscope transmits images of the colon as it bends and moves around the curves of the colon. The patient may be required to change positions so that the doctor can move the colonoscope. Air is also blown into the colon to expand the colon, which helps the doctor to see and examine clearly. You may experience mild cramps during the colonoscopy.
When the procedure is completed, the colonoscope is withdrawn slowly while the bowel lining is carefully examined.
Anything abnormal that is observed during the colonoscopy is removed for biopsy.
Polyps are also identified and removed.
Can any diseases be treated during the Colonoscopy?
Medicine is injected around wounds and diverticula that are bleeding.
Alternatively, heat is applied to cauterize the wounds.
A lasso-like device removes cancerous polyps
With the help of a balloon, strictures can be dilated
