The Chicago Classification

The Chicago Classification is a standardized system used by doctors to diagnose problems with how the esophagus (the tube that carries food from your mouth to your stomach) functions. It analyzes test results from esophageal motility studies, which measure how well the muscles in the esophagus work during swallowing. By categorizing different patterns of muscle activity and disorders, the classification helps clinicians identify conditions like achalasia or other motility issues, guiding appropriate treatment. Essentially, it provides a common language and framework for understanding complex esophageal movement abnormalities.
