ASGE Esophagology: Tailoring Management from Testing to Treatment (Live and Virtual) | July 2022-The Basics of HRM and The Chicago Classification

Video Transcription

Video Summary

In this video, Dr. Prakash Giawale discusses the basics of high-resolution manometry and the Chicago classification. He explains that high-resolution manometry involves using sensors on a catheter to record pressure throughout the esophagus, providing a detailed map of esophageal motility. The data collected is then converted into a visual representation known as a Klaus plot, which allows for real-time visualization of the esophageal sphincters and motor function. Dr. Giawale discusses various metrics used to assess motor function, including integrated relaxation pressure (IRP), distal latency (DL), and distal contractile integral. He also explains how high-resolution manometry has improved the diagnosis of achalasia and other motor outflow obstruction syndromes. The Chicago classification is an hierarchical system used to interpret the high-resolution manometry data and make diagnoses. Dr. Giawale explains the different subtypes of achalasia and other esophageal motility disorders. He also discusses additional tests that can be used to confirm or refute a diagnosis of outflow obstruction. In summary, high-resolution manometry and the Chicago classification are valuable tools for assessing esophageal motility and diagnosing motor disorders.
