Flexible sigmoidoscopy after age 50 has been recommended by the American Cancer Society for colorectal cancer screening. A questionnaire to assess the difficulties encountered in learning to perform this procedure was given to 19 surgical oncology fellows after a 3-month rotation in the Division of Colorectal Surgery. Sixteen (84%) trainees related that between 10-20 flexible sigmoidoscopies were necessary before they felt competent. The most difficult aspect of learning flexible sigmoidoscopy was the torquing technique followed by the ability to determine the location of the proximal bowel lumen. All 19 trainees rated the ability to recognize pathology as not difficult. In this group of surgical trainees, the mean number of flexible sigmoidoscopy performed before competency was established was 15; torquing the shaft of the sigmoidoscope was the most difficult aspect to learn. The majority of the trainees recorded that following the performance of 15-20 endoscopies, torquing became easier.

Colorectal cancer (CRC) ranks third in terms of global cancer prevalence and is the second most common cause of cancer-related mortality. Although CRC rates are decreasing in the United States, inequalities still exist despite the effectiveness of invasive screening methods, such as colonoscopy, flexible sigmoidoscopy, and computed tomography (CT) colonography in detecting colorectal cancer. Many current interventions promoting CRC screening do not utilize a modern theory-based approach, which has led to the low utilization of these screening methods.

Background And Aim: Colorectal cancer (CRC) is a significant global health burden, and screening can greatly reduce CRC incidence and mortality. Previous studies investigated the economic effects of CRC screening. We performed a systematic review to provide the cost-effectiveness of CRC screening strategies across countries with different income levels.

Positive results from cancer screenings, like a cancer diagnosis, can increase the risk of cardiovascular disease (CVD) mortality due to heightened psychological stress. However, positive screening results may also serve as a teachable moment to encourage the adoption of a healthier lifestyle. Consequently, the overall association between positive screenings and CVD mortality risk remains unclear.

Introduction: United States Multi-Society Task Force colonoscopy surveillance intervals are based solely on adenoma characteristics, without accounting for other risk factors. We investigated whether a risk model including demographic, environmental, and genetic risk factors could individualize surveillance intervals under an "equal management of equal risks" framework.
Methods: Using 14,069 individuals from the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial who had a diagnostic colonoscopy following an abnormal flexible sigmoidoscopy, we modeled the risk of colorectal cancer, considering the diagnostic colonoscopy finding, baseline risk factors (e.
