Abstract
Purpose of Review
Chicago Classification has standardized clinical approach to primary esophageal motility disorders. With new clinical data and advancing treatments, Chicago Classification has undergone multiple revisions to reflect updated findings and enhance diagnostic accuracy. This review will describe the recently published Chicago Classification version 4.0 (CCv4.0), which aimed to enhance diagnostic characterization and limit overdiagnosis of inconclusive esophageal motility diagnoses.
Recent Findings
Key revisions outlined in CCv4.0 include (1) a modified standardized HRM study protocol performed in supine and upright positions, (2) recommended ancillary testing and manometric provocation for inconclusive manometric diagnoses (3) the required presence of obstructive symptoms for conclusive diagnoses of esophagogastric junction outflow obstruction, distal esophageal spasm and hypercontractile esophagus, and (4) requirement of confirmatory testing for esophagogastric junction outflow obstruction.
Summary
These key modifications aim to improve diagnostic accuracy and consistency of clinically relevant esophageal motility disorders, and subsequently clinical outcomes.
