There was no effect of a flexible sigmoidoscopy screen on the reduction in proximal colon cancer incidence in either men or women; however, there was a slight statistically significant difference between sex in the reduction in all-site colorectal cancers in both intention-to-treat analysis (19% for women vs 30% for men; p=0.
Some highlights from the analysis: Four randomized trials including 458,002 patients showed that one-time or two-time screening with flexible sigmoidoscopy was associated with decreased mortality from colorectal cancer, compared with no screening, for an incidence rate ratio of 0.
1,3,4,9 It may be difficult to make an accurate preoperative diagnosis of SV without using sigmoidoscopy, CT, or MRI; the diagnosis is currently made under laparotomy or on autopsy in 10-15% of patients.
In the USA, screening for CRC using colonoscopy, flexible sigmoidoscopy or FOBT is recommended.
Unlike a colonoscopy, a sigmoidoscopy looks only at the rectum and lower portion of the colon.
In about 22% of cases, colonoscopy was performed as a direct effect of screening with flexible sigmoidoscopy.
Colonoscopy procedures are more complex and cost more to perform than sigmoidoscopy procedures.
Flexible sigmoidoscopy involves a thin, bendy tube with a camera attached to it being placed a short way into the rectum and lower bowel to look at the inside wall of the bowel.
Some require extensive bowel preparation, and flexible sigmoidoscopy and colonoscopy can result in accidental perforations.
For those at average risk, ACS recommends screening with 1) a fecal occult blood test (FOBT) or fecal immunochemical test (FIT) every year, 2) flexible sigmoidoscopy every 5 years, 3) an annual FOBT or FIT combined with flexible sigmoidoscopy every 5 years, * 4) double-contrast barium enema (DCBE) every 5 years, or 5) colonoscopy every 10 years (2).
In contrast, doctors recommend that flexible sigmoidoscopy, which uses a similar method to check a smaller portion of the colon, be repeated every 5 years.
Centers for Disease Control and Prevention that show that the typical cost of a screening procedure is about $10 to $25 for a fecal occult blood test, $150 to $300 for a flexible sigmoidoscopy, $250 to $500 for a double-contrast barium enema, and $800 to $1,600 for a colonoscopy.
Four key tests are used to detect the cancer--fecal occult blood test (FOBT), flexible sigmoidoscopy, double-contrast barium enema (DCBE), and colonoscopy.
As screening trial results for PSA, flexible sigmoidoscopy, chest X ray, and spiral computed tomography start to become available over the next decade, how do these results alter our understanding of population trends in incidence and mortality?
