Summary

Detection and removal of polyps during colonoscopy is crucial for the prevention of colorectal cancer. Indigo carmine spraying up to the colonic mucosa could probably increase the adenoma detection rate. The traditional method of dye spraying with spraying catheter or syringe would consume a lot of time and dye volume. Now, the more convenient auxiliary water supply channel can be used to spray indigo carmine. In order to explore the clinical application value of spraying indigo carmine solution by auxiliary water channel in high-risk population, we performed a prospective, randomized controlled trial to compare adenoma detection rate of conventional colonoscopy and chromoendoscopy.
