BACKGROUND The best and most cost-effective bowel cleansing regimen for patients undergoing flexible sigmoidoscopy is not known. The aim of this study was to compare patient tolerance, quality of preparation, and cost of 2 bowel cleansing regimens for flexible sigmoidoscopy. METHODS Two hundred fifty consecutive patients referred for screening flexible sigmoidoscopy were randomized to receive...

BACKGROUND Sigmoidoscopy is effective in colorectal cancer screening, but incomplete examinations may overlook colonic pathologies and delay diagnosis. This study aimed to explore risk factors for incomplete insertions of flexible sigmoidoscopy among Taiwanese. METHODS Healthy adults participating in health check-up in a tertiary medical center were invited for study. Subjects were recruited ...

BACKGROUND Recommended colorectal cancer (CRC) screening tests for adults ages 50 to 75 years include home fecal occult blood tests (FOBT), sigmoidoscopy with FOBT, and colonoscopy. A newer test, computed tomographic (CT) colonography, has been recommended by some, but not all, national organizations.

BACKGROUND & AIMS Screening endoscopy reduces colorectal cancer (CRC) incidence but the time course and magnitude of effects beyond 10 years after screening are unknown. We aimed to estimate the expected time course and magnitude of long-term impact of screening endoscopy on CRC incidence. METHODS We used Markov models based on the natural history of the disease along with data from the Germa...

Background and study aims Uptake of flexible sigmoidoscopy screening in the English Bowel Scope Screening (BSS) Programme is low. The aim of this study was to test the impact of a nonparticipant reminder and theory-based leaflet to promote uptake among former nonresponders (previously did not confirm their appointment) and nonattenders (previously confirmed their appointment but did not attend)...
