What this trial studies

This observational study aims to evaluate the correlation between portal pressure gradient measurements obtained through endoscopic ultrasound in two different positions: supine and left lateral decubitus. The study focuses on patients with liver cirrhosis and esophagogastric varices, addressing the limitations of the traditional hepatic venous pressure gradient measurement. By comparing the consistency of EUS-PPG measurements in these positions, the study seeks to determine if one position offers more reliable results than the other. The findings could enhance the clinical application of EUS-PPG in assessing portal hypertension.

Who should consider this trial

Good fit: Ideal candidates for this study are hospitalized patients with liver cirrhosis complicated by esophagogastric varices who are willing to consent to the procedure.

Not a fit: Patients with uncorrectable coagulopathy, thrombocytopenia, bacteremia, or those who are pregnant or outside the age range of 18 to 81 may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy and reliability of portal pressure measurements, leading to better management of patients with liver cirrhosis and varices.

How similar studies have performed: While EUS-PPG has shown promise in previous studies, the specific comparison of measurements in different positions is less explored, making this approach somewhat novel.
