About this study

Official title: A Clinical Study on the Diagnostic Value of Digital Tongue Diagnosis Model for High- and Low-risk Esophagogastroduodenal Varices in Patients With Liver Cirrhosis

The aim of this observational study is to establish an AI deep learning model that can dianosie high-risk varices for patients with cirrhosis effeciently.

The main question of this study is to esplore:

question 1: Developing a digital tongue diagnosis model, specifically a deep learning model to diagnose high-risk esophageal and gastric varices (HRV) associated with cirrhosis using sublingual vein images. Answering the question of whether the new tongue diagnosis method can accurately diagnose.

Question 2: Compare the diagnostic efficacy digital tongue diagnosis model with diagnostic models constructed using other biochemical indicators for HRV in cirrhosis, and answer the question of "how to use it optimally."

Question 3: Exploring the correlation between sublingual vein characteristics and Hepatic venous pressure gradient (HVPG).

Question 4: Compared with endoscopic examination results, validate the diagnostic performance of the model (AUC ≥ 0.90) and screen for key parameters of sublingual vein characteristics (such as sublingual vein varicosity diameter, vein length, color, etc.).

Question 5: Follow-up tongue examination images of patients with cirrhosis who underwent treatment (e.g., endoscopy, splenic embolization, TIPS, etc.) at 1, 2, and 3 years post-treatment were evaluated to assess the efficacy of digital tongue examination models in predicting high-risk esophageal and gastric variceal bleeding at 1, 2, and 3 years post-treatment, as well as the efficacy in predicting endoscopic treatment failure rates and patient mortality associated with bleeding.

Read the detailed description

Firstly, participants will be divided into two groups according to their degree of esophageal varices from endoscopic examination and CT report, including high-risk varices (HRV) group and low-risk varices (LRV) group. Secondly, participants will be asked to show their tongue, including the surface and sublingual veins of tongue, and the tongue images of each participants will be collected by researchers via camera. After finishing tongue image collection, participants will receive a professional tongue diagnosis report in Traditional Chinese Medicine and health suggestion. Finally, tongue images will be analyzed by AI deep learning model and some specifialized information will be estracted exactly. Besides, 60 patietns will be selected to eplore whtether sublingual vein characteristics is assoicated with HVPG. Finally, patietns will be followed up during 3 years, and gastric variceal bleeding, endoscopic treatment failure rates, and patient mortality risks related to bleeding will be analyzed.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. AUC of tongue diagnostic model

    Using endoscopic diagnostic criteria as the "gold standard," we calculated the area under the ROC curve (AUC), sensitivity, specificity, positive predictive value, and negative predictive value of the VIT-based digital tongue diagnosis model to evaluate its diagnostic performance in diagnosing HRV in cirrhosis.

    Measured: through study completion, up to 3 years

Secondary outcomes (4)
  1. ROC of biochemical characteristic

    Calculate the AUC valthe digital tongue diagnosis model.ue, sensitivity, specificity, positive predictive value, negative predictive value, and other relevant parameters of the ROC curve for the HRV diagnostic model for cirrhosis constructed based on biochemical indicators, and compare them with

    Measured: through study completion, up to 3 years

  2. Association between HVPG and sublingual vein

    The association between sublingual vein and HVPG

    Measured: through study completion, up to 3 years

  3. Characteristic of sublingual vein

    Key parameters for screening sublingual vein characteristics (such as sublingual vein varicosity diameter, vein length, color, etc.).

    Measured: through studyy completion, up to 3 years

  4. The rate of esophageal variceal bleeding, endoscopic treatment failure, and patient mortality

    The incidence of esophageal variceal bleeding, endoscopic treatment failure rate, and patient mortality related to bleeding in patients with cirrhosis 1, 2, and 3 years after diagnosis.

    Measured: through study completion, up to 3 years
