About Colonoscopy
The colonoscopy is performed by a doctor experienced in the procedure and lasts approximately 30-60 minutes.
Colonoscopy is a procedure that enables an examiner (usually a gastroenterologist) to evaluate the inside of the colon (large intestine or large bowel). The colonoscope is a four-foot long, flexible tube about the thickness of a finger with a camera and a source of light at its tip. The tip of the colonoscope is inserted into the anus and then is advanced slowly, under visual control, into the rectum and through the colon usually as far as the cecum, which is the first part of the colon. Usually, it also is possible to enter and examine the last few inches of the small intestine
Preparation for colonoscopy
What bowel preparation is needed for colonoscopy?
If the procedure is to be complete and accurate, the colon must be completely cleaned, and there are several different colonoscopy preparations. Patients are given detailed instructions about the cleansing preparation. In general, this consists of drinking a large volume of a special cleansing solution or several days of a clear liquid diet and laxatives or enemas prior to the examination. Instructions may also be given to avoid certain foods for a couple of days prior to the procedure
