Chicago classification

The Chicago Classification is a standardized system used by doctors to diagnose esophageal motility disorders, which affect swallowing. It analyzes results from high-resolution manometry (a test that measures the muscle contractions in the esophagus). By categorizing patterns of abnormal muscle movements, the classification helps identify conditions like achalasia or other disorders that impair swallowing. This framework ensures consistent diagnosis across providers, guiding appropriate treatment options. In essence, it’s a structured way to interpret complex pressure data from the esophagus to determine the cause of swallowing difficulties.
