Summary

Transjugular intrahepatic portosystemic shunt (TIPS) is the first-line therapy for patients with cirrhosis and refractory ascites. However, mental changes known as hepatic encephalopathy (HE) frequently occur after TIPS. There is no effective method to predict HE after TIPS. Oral glutamine challenge (OGC) and psychometric tests have been used to assess the risk for HE, but never in patients undergoing TIPS. Severe muscle loss may also predispose patients to HE. The aim of the present study is to assess if both the OGC and psychometric tests can accurately predict the development of overt HE after TIPS. Patients will be studied before TIPS and followed after TIPS for the development of HE. The role of muscle loss in favoring HE, as well as is possible reversibility after TIPS will also be investigated.
