Esophageal variceal bleeding is one of the serious and life-threatening complications of chronic liver disease (CLD). Studies have shown that the prevalence of esophageal varices (EV) in patients with liver cirrhosis is about 50%-60%. The annual incidence of variceal bleeding in these patients is about 5%-15%, and the rebleeding rate can reach 30%-40% within 6 weeks after the first bleeding. The 6-week mortality related to variceal bleeding is as high as 10%-20%, which seriously threatens the life safety of patients with liver disease. Clinically, esophagogastroduodenoscopy (EGD) is the gold standard for the diagnosis and grading of esophageal varices. However, EGD is an invasive examination, which has certain application limitations such as related complications and high cost, which limits the promotion and application of this technology.
Therefore, there is an urgent need for an accurate, convenient and non-invasive method for esophageal varices. To address this clinical pain point, Baveno VII guidelines state that spleen stiffness measurement (SSM) based on vibration-controlled transient elastography (TE) can be used as a noninvasive marker to predict esophageal varices (EV). Several studies have shown that SSM measured by TE has good diagnostic performance in relation to the occurrence and severity of esophageal varices. A study involving 191 patients with liver disease showed that spleen stiffness was significantly higher in patients with varices than in those without varices (63.69 vs 47.78 kPa, P\<0.0001), and the AUC of SSM for the diagnosis of EV was 0.74. In another study involving 260 patients with chronic liver disease, the AUC of SSM was 0.728 (95% CI: 0.665-0.791) for EV and 0.780 (95% CI: 0.714-0.846) for high-risk varix (HRV). The above results indicate that SSM has good clinical value in the prediction of EV.
Pro9000X, a liver function shear wave quantization detector based on vibration control TE, has been developed by Wuxi Hisiel Medical Technology Co., LTD. The device integrates ultrasound image positioning and TE function, aiming to achieve rapid, quantitative and non-invasive detection of liver stiffness measurement (LSM) and SSM. The results of EGD examination were used as the gold standard to evaluate the diagnostic performance of the spleen stiffness value detected by Pro9000X in patients with chronic liver disease, and the main evaluation indicators were the sensitivity and specificity of EV diagnosis. Secondary evaluation included AUROC, optimal cut-off value and diagnostic value of high-risk EV.

Patients with chronic liver disease who met the protocol inclusion and exclusion criteria
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.
Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
