Prediction of Esophageal Varices in Liver Cirrhosis Using Tongue Bioinformatics

The goal of this observational study is to compare the tongue bioinformatics of high-risk and low-risk patients with esophageal varices due to liver cirrhosis. The main question of this study is to explore whether there exists a relationship between the degree of esophageal varices and tongue bioinformatics in liver cirrhosis. it aims to answer 2 questions as below: question 1: If these is a significant difference in tongue bioinformatics between patients in liver cirrhosis with high-risk and low-risk of esophageal varices. Question 2; If tongue bioinformatics can be used as a diagnostic basic for testing esophageal varices in liver cirrhosis. Firstly, participants will be divided into two groups according to their degree of esophageal varices from electronic gastroscopy report and CT scan report including high-risk group and low-risk 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.
