CR: contractile response; EGJ: esophagogastric junction; FLIP: functional lumen imaging probe; GERD: gastroesophageal reflux disease; HRM: high resolution manometry; TBE: timed barium esophagogram.
* FLIP panometry evaluation for primary motor dysfunction is intended for clinical scenarios in which findings associated with secondary esophageal motor abnormalities, such as large hiatal hernia, stricture, or previous foregut surgery, are excluded based on endoscopy and clinical history.
