Real-world Application of the Chicago Classification Version 4.0 for Esophageal Manometry: Asian Multicenter Study.

ABSTRACT:

Background/aims

The Chicago classification version 4.0 (CC v4.0) proposes a standardized high-resolution manometry protocol for more sophisticated diagnosis of esophageal motility disorders. We aim to investigate the real-world application of CC v4.0 through multi-institutional surveys in Asian countries.

Methods

We requested a total of 161 questionnaires from members of the Asian Neurogastroenterology and Motility Association via Google Survey from March to June 2023. The questionnaire assessed CC v4.0 protocol compliance and diagnosis.

Results

Responses were received from 33 centers in 9 countries (18 in Korea, 5 in Japan, and 10 in others). Among these, anticholinergics were investigated in 14 centers (42.4%), and narcotic drugs in 16 centers (48.5%). Eight centers
