Chicago Classification v4.0 (CCv4.0) is the updated classification scheme for esophageal motility disorders using metrics from high‐resolution manometry (HRM). Fifty‐two diverse international experts separated into seven working subgroups utilized formal validated methodologies over two‐years to develop CCv4.0. Key updates in CCv.4.0 consist of a more rigorous and expansive HRM protocol that incorporates supine and upright test positions as well as provocative testing, a refined definition of esophagogastric junction (EGJ) outflow obstruction (EGJOO), more stringent diagnostic criteria for ineffective esophageal motility and description of baseline EGJ metrics. Further, the CCv4.0 sought to define motility disorder diagnoses as conclusive and inconclusive based on associated symptoms, and findings on provocative testing as well as supportive testing with barium esophagram with tablet and/or functional lumen imaging probe. These changes attempt to minimize ambiguity in prior iterations of Chicago Classification and provide more standardized and rigorous criteria for patterns of disorders of peristalsis and obstruction at the EGJ.

高分辨率测压法上的食管动力障碍:芝加哥分类 4.0 版©

芝加哥分类 v4.0 (CCv4.0) 是使用高分辨率测压法 (HRM) 指标对食管运动障碍进行更新的分类方案。分为七个工作小组的 52 名不同的国际专家在两年多的时间里使用经过正式验证的方法来开发 CCv4.0。CCv.4.0 的主要更新包括更严格和更广泛的 HRM 协议,其中包括仰卧和直立测试位置以及激发测试、食管胃交界处 (EGJ) 流出道阻塞 (EGJOO) 的精确定义、更严格的无效食管诊断标准基线 EGJ 指标的运动性和描述。此外,CCv4.0 试图根据相关症状将运动障碍诊断定义为确定性和不确定性,以及关于激发测试的结果以及使用食管钡片和/或功能性管腔成像探头进行支持性测试的结果。这些变化试图最大限度地减少芝加哥分类先前迭代中的歧义,并为 EGJ 的蠕动障碍和阻塞模式提供更标准化和严格的标准。
