Intra‐ and interrater reliability of the Chicago Classification of achalasia subtypes in pediatric high‐resolution esophageal manometry (HRM) recordings

Subtyping achalasia by high‐resolution manometry (HRM) is clinically relevant as response to therapy and prognosis have shown to vary accordingly. The aim of this study was to assess inter‐ and intrarater reliability of diagnosing achalasia and achalasia subtyping in children using the Chicago Classification (CC) V3.0.
