Sigmoidoscopy - Wikipedia, the free encyclopedia (572 words)
Flexible sigmoidoscopy enables the physician to look at the inside of the large intestine from the rectum through the last part of the colon, called the sigmoid or descending colon.
Flexible sigmoidoscopy is not sufficient to detect polyps or cancer in the ascending or transverse colon (two-thirds of the colon).
The colon and rectum must be completely empty for flexible sigmoidoscopy to be thorough and safe, so the physician will probably tell the patient to drink only clear liquids for 12 to 24 hours beforehand.
