Endoscopic aspects in diagnosis of gastroesophageal reflux disease and motility disorders: Bravo, capsule, and functional lumen imaging probe

Catheter-based testing remains the current standard of practice for the diagnosis of gastroesophageal reflux disease and esophageal motility abnormalities. Ambulatory pH testing and esophageal manometry have been in use for the past 40 years, but with the development of high-resolution manometry and multichannel intraluminal impedance testing, catheter-based testing has undergone significant recent technological improvement. Nonetheless, these tests continue to have limitations. In the case of ambulatory reflux testing, patient discomfort and limited activity remain significant problems.
