Objective: Transjugular intrahepatic portosystemic shunt (TIPS) is used for decompression of elevated portal pressure; however, there are potential complications. The aim of this study was to compare the risk of complications of TIPS in those who had an episode of infection within 6 months prior to TIPS to those without an infection prior.Methods: A retrospective chart review was performed on patients who underwent TIPS at a single transplant centre over 8 years. They were divided into two groups: patients without infection during the 6 months prior to TIPS (n=349) and those with an infection prior (bacterial/fungal) (n=53). The Wilcoxon rank-sum test was used to compare continuous variables while chi-squared analysis and Fisher’s exact test was used for categorical variables. Multiple logistic regression was used to ascertain the association between pre-TIPS infection status and likelihood of post-TIPS infection.Results: In the group of patients who had an infection before TIPS, 26.4% (n=14) had an episode of infection after the procedure, while in the group without infection prior, 16.2% (n=55) had an infection after the procedure (p=0.047; odds ratio: 2.08). In the pre-TIPS infection group, 54.7% (n=29) had an episode of portosystemic encephalopathy post-TIPS versus 39.6% (n=134) in the group without infection before TIPS (p=0.046; odds ratio: 1.93).Conclusion: Pre-TIPS infection within 6 months of TIPS procedure is a risk factor for post-TIPS portosystemic encephalopathy and infection. Further studies are needed to determine the potential benefit of antibiotic prophylaxis in patients who had an infection in the 6 months preceding TIPS placement.
