摘要慢性便秘是一种常见的功能性疾病，诊断主要依据病史和体格检查。实验室检查对于明确慢性便秘的病因、类型、严重程度和治疗效果具有重要意义。由中国医师协会肛肠医师分会组织牵头，召集国内相关领域的专家，结合国内外最新循证医学证据，对慢性便秘常用的不透X线标志物法结肠传输试验、结肠压力测定、肛门直肠压力测定、球囊逼出试验、钡灌肠检查、排粪造影检查、磁共振排粪造影、盆底神经肌肉功能检查和盆底超声检查9种实验室检查方法的适应证、检查方法、判断标准和临床价值进行归纳和整理，依据评估、制定和评价的分级系统（GRADE）进行证据质量评估和推荐强度分级，形成《慢性便秘检查与评估中国专家共识（2024版）》，旨在为规范开展相关检查和准确进行临床实践提供帮助和指导。

abstractsChronic constipation is a common functional bowel disease, and its diagnosis is based on history and physical examination. Laboratory examination is important for determining the cause, type, severity and treatment effect of chronic constipation. At present, the commonly used workup of chronic constipation includes X-ray, magnetic resonance, pelvic floor ultrasound, neuroelectrophysiology and colorectal manometry, etc., which are recommended in many constipation diagnosis and treatment guidelines, but there has been no consensus on various examination indications, examination methods, judgment criteria and clinical value norms in detail. Led by the Anorectal Physicians Branch of the Chinese Medical Doctor Association, the editorial department of the Chinese Journal of Gastrointestinal Surgery convened domestic experts in related fields to summarize and sort out common laboratory examination methods for chronic constipation in combination with the latest evidence-based medical evidence at home and abroad, and conducted evidence quality assessment and recommendation strength classification according to the GRADE system. The Chinese Expert Consensus on the Examination and Evaluation of Chronic Constipation (2024 edition) was thus formed to help and guide the standardized examination in clinical practice and accurately interpret its clinical value.
