Esophageal Impedance and Manometry Measurements and Dysphagia Symptom Scoring

Gastrointestinal (GI) motility problems are very common in the general population. Dysphagia, difficulty swallowing, is one of the most common issues in gastroenterology. In many patients, esophageal obstruction is not identified despite workup with upper endoscopy or barium swallow x-ray. Patients are often referred to the Motility Laboratory for evaluation of non-obstructive dysphagia. Transnasal esophageal manometry-impedance is a diagnostic test to measure the pressures and coordination of the esophagus during swallowing. The Endolumenal Functional Lumen Imaging Probe (EndoFLIP) is another instrument used to measure the lumen distensibility of the esophagus and pylorus. Both tests are FDA-approved and are currently being used in clinical practice. However, correlation of the results obtained from these tests with clinical syndromes and symptoms is not clearly understood. Furthermore, the relationship between esophageal impedance-manometry and EndoFLIP results has never been defined.

The primary Aim is to develop a registry of patients undergoing esophageal manometry-impedance and Endoflip from the GI Motility Lab at the IU University Hospital
