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

Video Transcription

Video Summary

In this video, Dr. Prakash Giawale provides a talk on the basics of high-resolution manometry and the Chicago classification. High-resolution manometry is a technique that allows for the visualization and measurement of esophageal motility using sensors placed along a catheter. This technology improves upon conventional manometry by providing more detailed and accurate measurements. Dr. Giawale discusses how high-resolution manometry works, including the recording of pressure tracings and the use of color to represent different amplitudes. He explains how this technique is used to assess esophageal motor function and identifies several metrics used in the evaluation, including integrated relaxation pressure, distal latency, and distal contractile integral. Dr. Giawale also discusses the use of high-resolution manometry in diagnosing motor outflow obstruction syndromes, such as achalasia, and outlines the Chicago classification system for categorizing motor disorders based on manometry findings. He highlights the importance of ruling out mechanical causes of esophageal symptoms and explores complementary tests, such as timed upright barium swallows and impedance planimetry, to further evaluate outflow obstruction. Finally, he discusses the treatment options for motor obstruction and other motor disorders identified through high-resolution manometry.
