Description of intervention(s) / exposure
During an endoscopic ultrasound procedure the portal pressure gradient is measured. Elevation of the portal pressure gradient assists in diagnosis and prognosis of cirrhosis.
Hepatic venous pressure gradient (HVPG) is the gold standard for evaluating the presence and severity of portal hypertension (PHTN). HVPG >10 mmHg defines clinically significant Portal hypertension, as this critical threshold predicts for increased risk of decompensation events, including decompensation following liver resection, and death.Endoscopic ultrasound-portal pressure gradient (EUS-PPG) is a novel TGA-approved alternative to HVPG that has been shown in pilot studies to be safe and technically successful for the evaluation and determination of PHTN. EUS-PPG can be performed simultaneously with routine variceal surveillance and can be repeated to provide longitudinal HVPG measurements. Data regarding use in clinical practice is limited. This prospective registry seeks to evaluate the clinical utility of EUS-PPG assessment across multiple tertiary centres. This is a multi-centre prospective registry designed to collect data relating to clinical EUS-PPG assessment, such that the role for EUS-PPG in PHTN investigation, identification, stratification and management may be better understood.
The EUS-PPG procedure takes approximately 30 minutes and will be performed once only. Participants will have routine blood tests prior to enrolling to determine eligibility and baseline comorbid status. There is no future specimens to be collected. Baseline demographical, clinical health data and baseline liver status (Bloods, Child Pugh score, abdominal ultrasound findings, fibroscan, medical examination) is collected at baseline. Procedural data is collected (presence of varices, location, high risk stigmata for bleeding, portal hypertensive gastropathy presence), EUS assessment of Portal and Hepatic veins, measurements of the portal vein and hepatic veins, points of access, technical success, calculation of the PPG, length of procedure time, medications administered, additional procedures required, post procedural recommendations. Complications immediate, immediate post-procedure, adverse events via phone calls at Day 7 and Day 30
There are no questionnaires to be collected by the participant for this registry. Longitudinal clinical data will be collected for up to 5 years on each participant

Outcomes
Primary outcome [1] 333106 0
All participants will undergo an endoscopic assessment of portal hypertension, which includes an endoscopy and EUS. EUS-PPG measurement will be performed by endosonographers trained in EUS-PPG, using the Echotip Ultra device (Cook Medical), which comprises a 25gauge FNA-needle, 90cm non-compressible tubing and a manometer.
Timepoint [1] 333106 0
Baseline -during endoscopic ultrasound (EUS) procedure
Secondary outcome [1] 415849 0
Successful portal pressure gradient (PPG) measurement (Yes/No). There is no radiology involved in this procedure. It is a direct sampling method via the use of a 25 gauge needle into the hepatic and portal veins. Able to achieve 3 consecutive attempts to sample the portal pressure, the mean pressure is calculated from the 3 measurements (for each the hepatic and portal veins).

Secondary outcome [2] 415850 0
Adverse events will be collected at a phone call at day 7 and day 30 post procedure. These are categorised as: Abdominal pain, bleeding, fever, perforation, damage to local structures, anaesthetic complication, other, death.

Statistical methods / analysis
There is no statistical methods / analysis attached to this prospective registry as it serves as registry of clinical data. This is for clinical data, endoscopic data, and safety data. Descriptive statistics may be employed in the future to evaluate clinical outcomes in relation to the EUS-PPG result. This may measure the longitudinal Model for end-stage liver disease (MELD) and Child Pugh trend, longitudinal liver/spleen stiffness trend and risk of development of de novo GOV, non-GOV varices or VNT.

Summary
Brief summary
Endoscopic ultrasound-portal pressure gradient (EUS-PPG) is a novel therapeutic goods administration (TGA) -approved alternative to hepatic venous pressure gradient (HVPG) that has been shown in pilot studies to be safe and technically successful for the evaluation and determination of portal hypertension. EUS-PPG can be performed simultaneously with routine variceal surveillance and can be repeated to provide longitudinal HVPG measurements. Data regarding use in clinical practice is limited. This prospective registry seeks to evaluate the clinical utility of EUS-PPG assessment across multiple tertiary centres.

Aims: to evaluate the feasibility and utility of EUS-PPG in clinical practice, safety, clinical applications and the potential for EUS-PPG data to inform clinical management. Correlate EUS-PPG measurements with longitudinal risk of liver-related events, and with a range of non-invasive biomarkers and clinical findings.
