EUS Guided Portal-systemic Pressure Gradient Measurement to Predict Treatment Response and Outcomes of Varices to Endoscopic Variceal Ligation in Patients With Chronic Hepatitis.
- Conditions
- Cirrhosis Portal
- Interventions
- Device: EUS guided portal pressure gradient measurement
- Registration Number
- NCT05597488
- Lead Sponsor
- Chinese University of Hong Kong
- Brief Summary
The aim of the current study is to assess if EUS-PPGM could predict the treatment response and outcomes of varices to endoscopic variceal ligation (EVL) in patients with chronic hepatitis. The hypothesis is that a high EUS-PPGM value at 3 months correlates with the presence of varices requiring EVL in patients that have received primary or secondary variceal prophylaxis on 1 year follow-up upper endoscopy.

Group Intervention Description EUS guided portal pressure gradient measurement EUS guided portal pressure gradient measurement At index OGD, the presence and severity of OV, GV and portal hypertensive gastropathy would be recorded. After endoscopic treatment of varices, recruited patients would undergo 1st measurement of EUS-PPG within 10-14 days after index OGD. The patients would then be enrolled into a variceal surveillance program and be started on B-blockers if not already prescribed. The patients would then be scheduled for another follow-up OGD at 3 months with measurement of the 2nd EUS-PPG. Finally, a third follow-up OGD and EUS-PPG would be performed in 1-year after 1st EUS-PPG. Endoscopic findings attributed to chronic cirrhosis would be assessed in the 3 months and 1 year OGD and the presence and severity of OV, GV and portal hypertensive gastropathy would be recorded.
- Primary Outcome Measures
Name Time Method Presence or absence of varices requiring EVL on 1 year follow-up upper endoscopy 1 year The number of patients with a high EUS-PPGM at 3 months will be correlated with the presence or absence of varices requiring EVL on 1 year follow-up upper endoscopy.
- Secondary Outcome Measures
Name Time Method Other outcome measurements 1 year The value of Day 0, 3 months or 1year EUS-PPG would be correlated with the severity of cirrhosis, re-bleeding, number of sessions of repeated EVL and mortality at 1 year. Safety of the procedure would also be assessed as 30-day adverse events.
