High resolution manometry in esophageal disorders

Abstract

Since a revised classification was published after the paper was accepted, let me briefly outline the changes in the classification that may be of interest to those involved in functional diagnostics. ( 1 ) What changes are visible in the Chicago-classification version 4.0 (CCv4.0)? Instead of the previous 10 sips of water in a lying position, it is necessary to do 10 sips of water in a sitting and 10 in a lying position. Exceptions are persons in whom there is a thorough suspicion of achalasia or who are at risk of aspiration of contents. For the diagnosis of ineffective motility, it is necessary to have >70% of ineffective swallows or ≥50% of missed swallows.
