A Short History of High-Resolution Esophageal Manometry.
C Prakash Gyawali, Peter J Kahrilas
PMID 34739589WHAT IT FOUND
This paper traces the history of esophageal manometry technology from line-tracing catheters to high-resolution systems and the Chicago Classification.
It describes how the tools evolved but reports no new patient outcomes or evidence on treatment efficacy.
What this paper is
This is a historical review of the development of high-resolution esophageal manometry technology and the Chicago Classification. It describes the evolution of catheter design and diagnostic criteria but reports no new patient outcomes or clinical trial results, so there is nothing here to change your practice on.

The easy way to misread this
Do not treat the description of improved diagnostic accuracy or standardized metrics as evidence that this specific historical review validates current clinical outcomes. The paper summarizes past technological developments and consensus definitions rather than presenting new data on patient recovery or treatment success.
