This is a single-center, prospective, observational study intended to include patients receiving TIPS for portal hypertension. Baseline data of enrolled patients were recorded, and samples of ascites, feces and urine were collected before surgery. Venous blood (superior mesenteric vein, hepatic vein, peripheral vein) from different parts of the entero-hepatic axis was retained during operation, and patients were followed up regularly for 2 years. The incidence of infection, hepatic encephalopathy, upper gastrointestinal hemorrhage and ascites in patients with portal hypertension who received TIPS intervention were observed within 3 months after operation. And the stent patency was observed within 2 years after surgery. To investigate the characteristics of microbial, protein and metabolic components on enterohepatic axis and their relationship with prognosis of patients with cirrhosis by detecting microbiome, proteome and metabolome.
