Colorectal cancer (CRC) is the third most common type of cancer worldwide and the second deadliest form of cancer in the United States. Studies on CRC screening show that for every 1% increase in a physician’s adenoma detection rate, the risk of colon cancer developing in their patients over the next year decreases by 3%. Thus, if physicians are proficient at finding and removing precancerous polyps during colonoscopy, cancer is less likely to develop. However, estimates suggest that up to 25% of adenomas are missed with current colonoscopy technologies, primarily due to poor visualization in folds and other difficult-to-detect areas. Modifiable factors to improve detection rates include colonoscopy team behaviors during procedures, endoscope design, and targeted education. Technological advances and strategies to improve visualization, as well as field of view, have improved detection rates in recent years, and more strategies are in development. In addition, when an adenoma is detected, the use of injectable solutions or viscous agents with methylene blue may provide long-lasting submucosal lift and cushion to reduce the risk of perforation during removal. This educational activity will focus on strategies to improve polyp identification and reduce endoscopic resection risks.
