The role of CT colonography in colorectal cancer screening.

Computed tomographic colonography (CTC) is a relatively noninvasive technique for large bowel imaging that has the ability to detect colorectal neoplasia. Already well established as a reliable diagnostic tool in symptomatic patients who are unable to undergo complete colonoscopy, it is now being considered as a viable method for population screening. Advances in technique over the past 10 yr make this an attractive alternative, including reduced bowel preparation and stool tagging, three-dimensional (3D) image reconstruction, computer-aided detection software, and low-radiation dose protocols.

Acceptance of flexible sigmoidoscopy and colonoscopy for screening and surveillance in colorectal cancer prevention.

Objectives: To study an individual's experience of either flexible sigmoidoscopy (FS) or colonoscopy in a colorectal cancer prevention programme.

Methods: Consecutive individuals in a Bowel Cancer Prevention Programme, who had either an unsedated FS or a colonoscopy with sedation, participated in a prospective cross-sectional questionnaire-based study.

Results: A total of 447 responses were obtained for 256 colonoscopies and 191 FSs (200 men [45%] and 247 women [55%]).

Comparison of endoscopic procedures for colorectal cancer screening in women with mammography and Pap smear.

Background: This study compared the experiences of women who underwent endoscopic screening for colorectal cancer vs. their experiences with breast and cervical cancer screening by mammography and Pap smear, respectively.

Methods: Women who had either flexible sigmoidoscopy or colonoscopy as a screening procedure for colorectal cancer were asked to return a questionnaire by mail.
