Purpose: Transjugular intrahepatic portosystemic shunt (TIPS) has been reported superior to large-volume paracentesis for refractory ascites, but post-TIPS encephalopathy is a major complication. We intended to assess the outcome of limited diameter TIPS on ascites control, mortality, and encephalopathy in patients with refractory ascites at our centre.
Methods: TIPS was successfully performed on 56 patients. Initial stent dilatation was to 6 mm, if there was a reduction in portal pressure gradient (PPG) >25%, further dilatation was not proposed.
Results: Either complete or partial response was obtained in 58%, 81%, 83%, and 93% of patients at 1, 3, 6, and 12 months, respectively. Mortality was 10%, 29%, 37%, and 50% at 1, 3, 6, and 12 months, respectively. In 27 patients (48%), a new episode of encephalopathy developed, but only 6 (22%) were grade III or IV and 23 (85%) responded quickly to treatment.
Conclusions: The results of our study confirm the efficacy of TIPS for refractory ascites. The use of narrow-diameter dilatation without aiming at lowering the PPG below a certain threshold might simplify the procedure and the follow-up for these patients.
