Colonoscopy, Pain, Unsedated
Conditions
Brief summary
Colonoscopy is the gold standard in the diagnosis and treatment colorectal disease, but due to the uncomfortable or even painful procedure, a part of people unwilling to undergoing the examination and giving analgesic agents were recommended in several guidelines. However, use of analgesic agents have their own drawbacks, and nearly 70% patients felt no pain or only mild discomfort with the unsedated colonoscopy, routine administration of sedative or analgesic agents to all patients was considered as unnecessary. However, unsedated colonoscopy was thought to be an option for some but not for all, therefore a method to identify which patients at high risk for painful colonoscopy in preoperational stage is necessary.
