Application prospect of endoscopic ultrasound-guided portal pressure gradient measurement / 临床肝胆病杂志

ABSTRACT

Portal pressure measurement plays an important role in the diagnosis and evaluation of portal hypertension, and at present, there is still no unified method for the assessment of portal vein pressure. With the wide application of endoscopic ultrasound in digestive system diseases, endoscopic ultrasound-guided portal pressure gradient (EUS-PPG) measurement was included in the research agenda of the 2021 Baveno-VII conference, thus attracting widespread attention of scholars. This article reviews portal pressure measurement techniques, the development of EUS-PPG measurement technique, and two commonly used methods for EUS-PPG measurement in China and globally and elaborates on the application prospect of EUS-PPG measurement technique. A number of studies around the world have shown that EUS-PPG measurement technique is a direct, minimally invasive, simple, accurate, and radiation-free technique with strong clinical operability, and it is an important supplement to portal pressure measurement methods and may gradually become one of the main methods for portal pressure measurement.
