Liver Cirrhosis with Refractory Ascites: TIPS vs. Repeated Paracentesis
A 60-year-old woman with HCV cirrhosis (Child-Pugh class C, MELD 22) has refractory ascites despite sodium restriction and high-dose diuretics. She requires large-volume paracentesis every 2 weeks. She has no history of encephalopathy, but her serum bilirubin is 3.5 mg/dL, INR 1.9, and creatinine 1.6 mg/dL. She is evaluated for TIPS. The team is concerned about the risk of post-TIPS hepatic encephalopathy and worsening liver function. The patient is eager to avoid frequent procedures and asks about the benefits and risks.
1. What are the indications and contraindications for TIPS in this patient? How does her MELD score influence the decision?

TIPS is indicated for refractory ascites, variceal bleeding, and hepatic hydrothorax. Contraindications include severe hepatic encephalopathy, severe pulmonary hypertension, heart failure, and advanced liver failure (MELD >18–20 in some centers). This patient has Child-Pugh C and MELD 22, which is at the upper limit for TIPS due to high risk of post-procedure liver failure and encephalopathy. However, TIPS can be considered if the benefit of controlling ascites outweighs the risk. Her lack of prior encephalopathy is favorable. The decision should be individualized, often involving a multidisciplinary team. If TIPS is performed, a covered stent is preferred. The MELD score predicts mortality; a higher score indicates higher risk, so careful selection is crucial.
2. What are the alternatives to TIPS for refractory ascites, and how do they compare in terms of outcomes?
Read the worked answer
Alternatives include repeated large-volume paracentesis with albumin infusion, peritoneovenous shunt (rarely used due to complications), and liver transplantation. Repeated paracentesis is safe but burdensome and does not improve survival. TIPS improves survival in selected patients and reduces the need for paracentesis, but increases the risk of encephalopathy. In this patient, given her MELD 22, TIPS may be high-risk; thus, continued paracentesis with albumin (6–8 g per liter of ascites removed) may be a safer option while awaiting transplantation. She should be referred for transplant evaluation. The choice depends on local expertise and patient preference. A shared decision-making approach is essential.
