A New Ultrasound-Guided Esophageal Variceal Pressure-Measuring Device

Abstract

Two pressure-measuring devices were developed to determine intravariceal pressure in a model varix system. These devices demonstrate a low percent error and a high correlation to the actual variceal pressures with low intra- and interobserver variability. These devices have the potential to measure all the variables of the Laplace equation for wall tension. We plan to test these devices in human subjects.
