Flexible sigmoidoscopy is a member in good standing in the family of
screening tests for colorectal cancer. Consistent evidence shows that even
a single screening sigmoidoscopy reduces mortality from colorectal cancer
by two thirds in the area examined, about half of the large bowel.1- 4 All major
screening guidelines recommend sigmoidoscopy, often coupled with fecal occult
blood testing.5- 7 In
the United States, more than half of patients appropriately screened have
had sigmoidoscopy.8 The cost-effectiveness
of screening sigmoidoscopy compares favorably with other recommended screening
tests for colorectal cancer9 and with screening
for other cancers.
