Brief Summary

A observational diagnostic study will be conducted to compare the performance of liver stiffness and spleen stiffness measured by 2D-shear wave elastography (2D-SWE) and transient elastography (TE) for diagnosing gastroesophageal varices (GOV) in people with compensated Advanced Chronic Liver Disease (cACLD), and explore the cut-off value of 2D-SWE for diagnosing GOV.

Conditions

Liver Cirrhosis; Liver Fibrosis; Portal Hypertension

Keywords

2D-SWE; Liver Cirrhosis; Liver Stiffness; Spleen Stiffness; Gastroesophageal Varices

Outcome Measures

Primary Outcomes (5)

• Sensitivity of TE and 2D-SWE

  True Positive/ (True Positive+False Negative) ×100%

  Through study completion, an average of 2 year

• Specificity of TE and 2D-SWE

  True Negative/ (True Negative+False Positive) ×100%

  Through study completion, an average of 2 year

• Positive Predictive Value of TE and 2D-SWE

  True Positive/ (True Positive+False Positive) ×100%

  Through study completion, an average of 2 year

• Negative Predictive Value of TE and 2D-SWE

  True Negative/ (True Negative+False Negative) ×100%

  Through study completion, an average of 2 year

• Overall diagnostic performance of TE and 2D-SWE

  Measured by the area under the receiver operating characteristic curve (AUROC). The test accuracy level is considered high when the AUROC value is ≥ 0.9.

  Through study completion, an average of 2 year

Study Arms (1)

study group

All participants included will be in one study group.

Diagnostic Test: Transient elastography (TE) and 2D-shear wave elastography (2D-SWE)

Interventions

Transient elastography (TE) and 2D-shear wave elastography (2D-SWE) DIAGNOSTIC_TEST

Index test: TE examination will be completed by experienced nurses, requiring fasting for more than 4 hours before the examination and an interval of no more than 1 week from the abdominal ultrasound and 2D-SWE examination. The report will be considered highly reliable only if IQR/med is ≤ 30%, at least 10 successful acquisitions are obtained, and the success rate is at least 60%. Abdominal ultrasound and 2D-shear wave elastography (2D-SWE) will be completed by a sonographer, the interval between ultrasonic examination and laboratory tests should be less than a week, and the patients should fast for at least 4 hours before the examination. Reference standard: Gastroscopy will be completed and reported by experienced endoscopists, requiring no more than 1 month between gastroscopy and ultrasound examination, and patients should fast for at least 8 hours before gastroscopy.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Patients with chronic liver disease who visit Fifth Affiliated Hospital, Sun Yat-Sen University will be enrolled from October 2023 to January 2025. Their liver stiffness measured by transient elastography (TE) should be at least 10kPa no previous decompensation symptoms.

You may qualify if:

• Age≥18 years old;
• Chronic liver disease (alcoholic liver disease, chronic hepatitis B, chronic hepatitis C or non-alcoholic fatty liver disease);
• Liver stiffness ≥10kPa measured by transient elastography (TE);
• No previous decompensation-related manifestations (such as ascites, gastrointestinal varicose bleeding, hepatic encephalopathy, etc.);
• Informed consent has been signed.

You may not qualify if:

• Hepatocellular carcinoma or other advanced malignant tumor;
• Acute liver disease or ALT≥5×ULN;
• A history of splenectomy or splenic embolism;
• Acute or chronic thrombosis of the portal vein;
• Pregnancy or HIV infection;
• A history of transjugular intrahepatic portosystemic shunts (TIPs), endoscopic variceal ligation(EVL) , hardener or tissue gel therapy;
• A history of using non-selective beta blockers (NSBB) or diuretic in the last 3 months;
• Persistent substance abuse other than alcohol;
• There are conditions that seriously affect TE and 2D-SWE measurements (such as the intercostal space is too narrow, BMI≥30, etc.);
• There are contraindications of gastroscopy (such as heart failure, severe coagulation dysfunction, hepatic encephalopathy, etc.);
