Since the original version of "Chinese guideline regarding bowel preparation for gastrointestinal endoscopy" was published in 2013, bowel preparation has been widely investigated around the world. In order to improve the quality of bowel preparation, this guideline is an official statement issued by Digestive Endoscopy Special Committee of Endoscopic Physicians Branch of Chinese Medical Association and Cancer Endoscopy Committee of China Anti-Cancer Association. Domestic special experts were invited to search and grade the relevant literature published. An expert seminar was held, in which experts discussed and identified the recommendations, assessed the power of recommendations and the quality of evidence using the "grading of recommendations assessment, development and evaluation (GRADE)" system. The guideline offers practical recommendations for endoscopists regarding the whole procedure of bowel preparation including aims and requirements, preoperative education, diet restriction, the options of intestinal cleansing agents, antifoaming agents, contraindications, preparation for specific patients, and bowel preparation for enteroscopy and capsule endoscopy.
自第1版《中国消化内镜诊疗相关肠道准备指南（草案）》2013年发布以来，国内外消化内镜领域对肠道准备的研究不断深入。为了更好地指导肠道准备，中国医师协会内镜医师分会消化内镜专业委员会联合中国抗癌协会肿瘤内镜学专业委员会牵头对该指南进行了更新。通过邀请国内相关领域专家对国内外有关文献进行检索、分级，并召开专家研讨会，经专家讨论并确定推荐的条目，采用"推荐等级的评估、制定与评价（GRADE）系统"对各推荐条目的证据质量及推荐强度进行评估。本指南从肠道准备的目的与要求、患者告知及宣教、饮食限制、常用肠道清洁剂选择与用法、祛泡剂使用、禁忌证、特殊患者的肠道准备、小肠镜及胶囊内镜的肠道准备等8个方面，对内镜诊疗相关肠道准备提供指导，供临床医师参考。.
