Transjugular intrahepatic portosystemic shunt: current status.

Area of Science:

• Interventional Radiology
• Hepatology
• Gastroenterology

Background:

• Portal hypertension complications significantly impact patient morbidity and mortality.
• Transjugular intrahepatic portosystemic shunt (TIPS) emerged as a treatment option in the 1980s.
• TIPS is applied to various complications including variceal bleeding, ascites, and hepatorenal syndrome.

Purpose of the Study:

• To review the applications and efficacy of TIPS in managing portal hypertension complications.
• To evaluate the comparative effectiveness of TIPS against standard therapies.

Main Methods:

• Review of existing literature and clinical trials comparing TIPS with standard treatments.
• Analysis of outcomes including complication control, survival, and adverse events like encephalopathy.

Main Results:

• TIPS demonstrated superior control for refractory cirrhotic ascites and prevention of variceal rebleeding compared to standard therapies.
• No significant improvement in survival was observed in patients undergoing TIPS.
• A notable increase in the incidence of hepatic encephalopathy was reported in patients receiving TIPS.

Conclusions:

• The application of TIPS for ascites control and variceal rebleeding prevention should be reserved for carefully selected patients.
• Further controlled trials are necessary to establish the role of TIPS in other indications like Budd-Chiari syndrome and hepatorenal failure.
• TIPS may be considered as salvage therapy until more evidence supports its broader use.
