Same Session Validation of a Custom-Built 22G With the Commercial 25G System for EUS-Guided Portal Pressure Gradient Measurement.

ABSTRACT:

Background and aims

Endoscopic ultrasound-guided portal pressure gradient (EUS-PPG) measurement is a promising alternative to hepatic venous pressure gradient (HVPG) assessment, especially in settings where HVPG is unavailable or limited. The commercial 25-gauge (25G) system showed good correlation with the hepatic venous pressure gradient (HVPG). However, the 25G has drawbacks due to its small caliber and the proprietary pressure transducer. The aim of this study was to validate a custom-built 22G conventional intravascular pressure transducer system (22G EUS-PPG).

Methods

In this prospective cohort study, 26 patients underwent EUS-PPG measurement using both systems during the same session. The primary outcome was the correlation of PPG values. Secondary outcomes included t
