Flexible Sigmoidoscopy

Flexible sigmoidoscopy is a routine outpatient procedure in which the inner lining of the lower large intestine is examined. Flexible sigmoidoscopy is commonly used to evaluate gastrointestinal symptoms, such as abdominal pain, rectal bleeding, or changes in bowel habits. It is also performed to screen people older than age 50 for colon and rectal cancer.

During the procedure, a doctor uses a sigmoidoscope, a long, flexible, tubular instrument about 1/2 inch in diameter, to view the lining of the rectum and the lower third of the colon (the sigmoid colon).
