[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.
