Colorectal cancer (CRC) is one of the most common malignant tumors in the clinic. Colonoscopy is an important means of screening, diagnosis and treatment of colorectal diseases. The accuracy of diagnosis and the safety of treatment are closely related to the quality of intestinal preparation. Inadequate bowel preparation leads to poor effect of colonoscopy, which will reduce the effectiveness and safety of colonoscopy, increase the difficulty and time of colonoscopy, and increase the need of repeated colonoscopy. There are many factors that lead to poor bowel preparation. Recently, a number of studies at home and abroad have evaluated the risk factors related to insufficient bowel preparation. Obesity, men, older age, previous colon surgery history, accompanied by other diseases (such as diabetes, Parkinson's disease), taking antidepressants and other factors can affect the effect of bowel preparation. Although the research of intestinal preparation intervention and education methods has made a lot of progress, but in a series of reports, there are still a considerable number of patients in colonoscopy problems of intestinal preparation. At present, there are few researches on individualized intervention aiming at the risk factors of inadequate bowel preparation in China, so it is urgent to explore individualized bowel preparation scheme suitable for different populations. Therefore, the purpose of this experiment is to study individualized dryness aiming at the risk factors of insufficient bowel preparation in patients with the risk factors of insufficient bowel preparation The effect of pre-treatment on the quality of intestinal preparation can provide reference for improving the quality of intestinal preparation in patients with inadequate intestinal preparation.
