Abstract
High -resolution manometry (HRM) is a diagnostic tool for surgeons, gastroenterologists and other healthcare professionals to evaluate esophageal physiology. The Chicago Classification (CC) system is based on a consensus of worldwide experts to minimize ambiguity in HRM data acquisition and diagnosis of esophageal motility disorders. The most updated version, CCv4.0, was published in 2021; however, it does not provide step-by-step guidelines (i.e., for beginners) on how to assess the most important HRM metrics. This paper aims to summarize the basic guidelines for conducting a high -quality HRM study including data acquisition and interpretation, based on CCv4.0, using Manoview ESO analysis software, version 3.3 (Medtronic, Minneapolis, MN).
