Transjugular intrahepatic portosystemic shunt with or without variceal embolization to prevent variceal rebleeding: an updated meta-analysis.

TIPS with embolization can be an effective strategy for preventing variceal rebleeding; however, our results should be interpreted cautiously as most data were observational and the technical quality of the embolization is questionable. Further RCTs are required using the proper techniques of embolization and comparing TIPS with embolization with other treatment modalities such as endoscopic ligation, and balloon-occluded retrograde transvenous obliteration.
