Consensus of Experts on Clinical Application of Electronic Sigmoidoscopy(2020 Edition)

With the development of society, the incidence rate of colorectal cancer has increased significantly, and the incidence of colorectal cancer in the rectum sigmoid segment accounted for 70% to 80% of colorectal cancer. Electronic rectosigmoid colonoscopy is an important method for screening and general investigation of colorectal cancer, which has the advantages of simple manipulation, less pain, low price and reliable results, and it can be used for the diagnosis and treatment of rectal polyps and monitoring of colitis diseases. At present, there is no clear and unified technical specification for bowel preparation and operation process of electronic sigmoid colonoscopy. In order to standardize the application of electronic sigmoidoscopy and better assist the screening and prevention of colorectal cancer, Beijing Anorectal Society organized 19 experts with rich clinical experience in the field of anorectal cancer in China. Through repeated discussions and questionnaire survey on the basis of evidence-based medicine, the Consensus of Experts on Clinical Application of Electronic Sigmoidoscopy(2020 Edition)was formed.
