Early-Recurrent Overt Hepatic Encephalopathy Is Associated with Reduced Survival in Cirrhotic Patients after Transjugular Intrahepatic Portosystemic Shunt Creation
Clinical question: How well does the presence of overt hepatic encephalopathy (OHE) occurring within 3 months of a transjugular intrahepatic portosystemic shunt (TIPS) placement predict survival?
Take-away point: Early recurrence of OHE was related to poorer long-term survival for cirrhotic patients who underwent the TIPS procedure.

Study design: Retrospective cohort study
Funding sources: Self-funded/NA
Setting: Single institution
(a) Cumulative probability of OHE and survival in 304 cirrhotic patients with TIPS. (b) Cumulative probability of secondary OHE in 304 cirrhotic patients with TIPS. (c) Cumulative probability of survival in 304 patients with cirrhosis undergoing TIPS.
(a) Probability of survival in patients with and without early OHE. (b) Probability of survival in patients with and without early-single OHE. (c) Probability of survival in patients with and without early-recurrent OHE.
This study provides valuable insight into a patient’s prognosis following the development of HE after TIPS. Previous research has debated the association between HE and mortality following TIPS, however the results of the present study further supports the conclusion that HE following TIPS is associated with increased mortality. The large sample size coupled with rigorous statistical analyses bolsters the results of this study. Patient’s that develop recurrent OHE within 3 months of TIPS have significantly poorer survival than those with only one occurrence of OHE. Given that 44% of patients who had a first OHE episode after a TIPS would experience recurrent OHE within 3 months, intense surveillance and therapy should be pursued during this time period. It should be noted that a majority of the patients in this study developed cirrhosis secondary to Hepatitis B (84%), so the results may not be completely generalizable to patients with other chronic liver disease.
