The endoscopic pressure study integrated system (EPSIS) can be used to endoscopically evaluate lower esophageal sphincter (LES) function. As such, it is also an adjunct diagnostic method to 24-hour pH monitoring. Since air is continuously pumped into the stomach; it functions as a stress test of the potential of the LES. We believe that EPSIS may be a useful modality in the new field of “functional endoscopy”.
