Highlights |
• | A meta-analysis was performed to compare the clinical efficacy of TIPS using 8mm covered stents to that using 10mm diameter covered stents in patients with liver cirrhosis. |
• | The 8mm covered stent group had greater one-year (odds ratio [OR], 2.88; P=0.003) and three-year overall survival (OR, 1.81; P=0.04) and lower hepatic encephalopathy rate (OR, 0.69; P=0.04) compared to 10mm covered stent group. |
• | No significant differences in variceal rebleeding (OR, 0.80; P=0.67) was found between the two stents but shunt dysfunction rate was lower in 10mm covered stent group (OR, 2.26; P=0.003). |
Abstract |
Purpose |
The purpose of this study was to make a systematic review and meta-analysis to determine the stent diameter (8mm vs. 10mm) that conveys better safety and clinical efficacy for transjugular intrahepatic portosystemic shunt (TIPS).
Materials and methods |
Four databases were used to identify clinical trials published from inception until March 2020. Data were extracted to estimate and compare one-year and three-year overall survivals, hepatic encephalopathy, variceal rebleeding, and shunt dysfunction rates between patients with 8mm covered stents and those with 10mm covered stents.
Results |
Five eligible studies were selected, which included 489 patients (316 men, 173 women). The 8mm covered stent group had higher efficacy regarding one-year or three-year overall survival (odds ratio [OR], 2.88; P=0.003) and (OR, 1.81; P=0.04) and lower hepatic encephalopathy (OR, 0.69; P=0.04) compared with 10mm covered stent group. There were no significant differences in variceal rebleeding rate (OR 0.80; P=0.67). However, shunt dysfunction was lower in 10mm covered stent group (OR, 2.26; P=0.003).
Conclusions |
Our results suggest that the use of 8mm covered stents should be preferred to that of 10mm covered stents for TIPS placement when portal pressure is frequently monitored.
