[Clinical practice guideline on the evaluation and management of chronic constipation for Chinese adults (2022 edition)].

Chinese Society of Colorectal Surgery firstly issued guidelines on the chronic constipation in 2008, which played a positive role in the standardization of chronic constipation surgery in China. In recent years, some progress has been made in the basic and clinical researches on chronic constipation. But in terms of clinical practice, there is still a lack of gold standard and high-level clinical research evidence, and surgeons have no authoritative reference in preoperative evaluation, operation selection and efficacy evaluation. In order to further standardize the diagnostic assessment and surgical treatment of chronic constipation, it is necessary to update the guidelines. Based on the published literatures combined with the clinical experience of experts, the "Clinical practice guideline on the evaluation and management of chronic constipation for Chinese adults (2022 edition)" has been formulated, which aims at the common problems in constipation assessment and treatment, is problem-oriented, and puts forward rationalization suggestions on the basis of evidence. It is expected to contribute to the learning and practice on constipation for Chinese surgeons and other relevant medical practitioners, and improve the overall diagnosis and treatment level of constipation surgery in China.中华医学会外科学分会结直肠外科学组于2008年第一次发布的慢性便秘的外科诊治指南，对我国慢性便秘外科诊治的规范化开展起到了积极的作用。近年来，有关慢性便秘的基础与临床诊疗研究有了一定的进展，但在临床实践方面目前尚缺乏金标准与高级别的临床研究证据，外科医师在术前评估、术式选择、术后疗效评价等方面缺乏权威的参考。为进一步规范慢性便秘的诊断评估与外科处理，中华医学会外科学分会结直肠外科学组遴选我国便秘外科领域相关专家组成《中国成人慢性便秘评估与外科处理临床实践指南》编审委员会，通过研读国内外相关文献及结合专家们的临床经验，对该指南进行了更新。本次制定的《中国成人慢性便秘评估与外科处理临床实践指南》以便秘的临床评估和处理（非手术处理和手术治疗）中存在的常见问题为导向，以循证为基础，囊括当前国内外研究的主要结果与结论，依据GRADE系统进行证据质量评估及推荐强度分级。期望有助于中国便秘外科医生、以及其他相关医疗从业人员的学习与实践，提高我国便秘外科的总体诊治水平。.
