Clinical Trial Summary

TIPS is a standard for the treatment of portal hypertension related complications. However, it remains at risk of HE after TIPS (around 40% the first year). Dysbiosis plays a key role in pathophysiology of HE. Polydextrose (PDX) is consider as a prebiotic. Preliminary studies showed that PDX: 1. modified gut microbiota, enhancing "good bacteria" 2. improved gut permeability and immunity in 2 experimental models: infarction and colitis. The aim of this study is to assess PDX efficacy to prevent HE during the first 6 months after TIPS in cirrhotic patients.

Preliminary studies showed that PDX: 1. modified gut microbiota, enhancing "good bacteria" 2. improved gut permeability and immunity in 2 experimental models: infarction and colitis. Patients will receive PDX 15 days prior to and 6 months after TIPS. We will assess the cumulative incidence of HE 6 months after TIPS. Patients will be followed-up for 12 months after TIPS. ;
