摘要
A method for characterization of a patient's esophagus may include receiving data measured by an impedance and high resolution manometry catheter in an esophagus in which the data may be representative of a pressure and/or an impedance associated with a swallowing event. The method may also include determining a cross-sectional area of the esophagus based on the received data and a pre-determined amount of a bolus consumed during the swallowing event. Systems and apparatus for characterizing a patient's esophagus may also include measuring data with a high resolution manometry catheter to determine the cross-sectional area, work, and compliance of the esophagus as a function of time during a swallowing event. Averaged data may establish a database of normal values for work done and compliance and allow for comparison of a patient to normal pathology.
