Brief summary
For this study, the investigators will be collecting data based on patients' random selection to two different approved standard of care treatments for ascites: Subjects will get randomized into either Group A: Large Volume Paracentesis (LVP) with albumin infusion, or Group B: an early transjugular intrahepatic portosystemic shunt (TIPS) procedure.
Detailed description
End Stage Liver Disease (ESLD) severely impacts body function leading to elevated blood pressure within the liver called "portal hypertension." One of its subsequent symptoms is ascites, or fluid accumulation in the abdomen. One standard treatment to relieve ascites is large volume paracentesis (puncture of the abdomen to drain the fluid). Another standard treatment is the TIPS procedure, which involves creating a shunt (small passage allowing fluid movement) within the liver to relieve the increased blood pressure in the liver. For this study, the investigators will be collecting data based on patients' random selection to two different approved standard of care treatments for ascites: Subjects will get randomized into either Group A: Large Volume Paracentesis (LVP) with albumin infusion, or Group B: an early transjugular intrahepatic portosystemic shunt (TIPS) procedure. The study will include about 68 patients (34 patients will be selected for Group A: continuing conservative treatment of LVP with albumin infusion, and 34 patients will be selected for Group B: undergoing early TIPS with Gore®Viatorr®CX). Each patient will be followed up at 1 month, 3 months, 6 months, and 12 months. The primary objective of this study is to evaluate the overall clinical efficacy in symptom relief of ascites of patients receiving the Gore® Viatorr® CX in early TIPS procedures compared to LVP (large volume paracenthesis). In order to so, the investigators will be using information found in patient medical records, collected as a part of standard of care, to analyze clinical outcomes, complications, and the rate of secondary interventions at follow-up.
Interventions
DEVICEGore® Viatorr® Endoprosthesis with controlled expansion
TIPS (Transjugular Intrahepatic Portosystemic Shunt) is a minimally invasive procedure in which a new path is made through the liver to carry blood from the portal vein to the heart, thus helping to alleviate the problems associated with elevated portal vein pressure.
PROCEDURELarge Volume Paracentesis with albumin infusion
For therapeutic (large-volume) paracentesis, a 14-gauge cannula attached to a vacuum aspiration system is used to collect up to 8 L of ascitic fluid. Concurrent infusion of IV albumin is recommended during large-volume paracentesis to help avoid significant intravascular volume shift and postprocedural hypotension.
