Transjugular intrahepatic portosystemic shunt (TIPS) is an essential procedure for the treatment of portal hypertension but can result in hepatic encephalopathy (HE), a serious complication that worsens patient outcomes. Investigating predictors of HE after TIPS is essential to improve prognosis. This review analyzes risk factors and compares predictive models, weighing traditional scores such as Child-Pugh, Model for End-Stage Liver Disease (MELD), and albumin-bilirubin (ALBI) against emerging artificial intelligence (AI) techniques. While traditional scores provide initial insights into HE risk, they have limitations in dealing with clinical complexity. Advances in machine learning (ML), particularly when integrated with imaging and clinical data, offer refined assessments. These innovations suggest the potential for AI to significantly improve the prediction of post-TIPS HE. The study provides clinicians with a comprehensive overview of current prediction methods, while advocating for the integration of AI to increase the accuracy of post-TIPS HE assessments. By harnessing the power of AI, clinicians can better manage the risks associated with TIPS and tailor interventions to individual patient needs. Future research should therefore prioritize the development of advanced AI frameworks that can assimilate diverse data streams to support clinical decision-making. The goal is not only to more accurately predict HE, but also to improve overall patient care and quality of life.

This meta-analysis aimed to evaluate the performance of different risk assessment models (RAMs) for survival after Transjugular Intrahepatic Portosystemic Shunt (TIPS) in patients with cirrhotic portal hypertension.

A systematic search of PubMed, WOS, Embase, Cochrane, and CNKI from inception to February 2023 was conducted. We comprehensively reviewed and aggregated data from numerous studies covering prevalent RAMs such as Child-Turcotte-Pugh, the Model for End-Stage Liver Disease (MELD), MELD-Sodium (MELD-Na), the Freiburg Index of Post-TIPS Survival (FIPS), Bilirubin-platelet, Chronic Liver Failure Consortium Acute Decompensation score, and Albumin-Bilirubin grade across different timeframes. For this study, short-term is defined as outcomes within a year while long-term refers to outcomes beyond one year. The area under the receiver operating characteristic (AUC) curve or Concordance Statistics was chosen as the metric to assess predictive capacity for mortality outcomes across six predetermined time intervals. Mean effect sizes at various time points were determined using robust variance estimation.

MELD consistently stood out as a primary short-term survival predictor, particularly for 1 month (± 2 weeks) (AUC: 0.72) and 3 months of (± 1 month) survival (AUC: 0.72). MELD-Na showed the best long-term predictive ability, with an AUC of 0.70 at 3.5 years (± 1.5 years). FIPS performed well for 6 months of (± 2 months) survival (AUC: 0.68) and overall transplant-free survival (AUC: 0.75). Efficacy nuances were observed in RAMs when applied to particular subgroups. Meta-regression emphasized the potential predictor overlaps in models like MELD and FIPS.

This meta-analysis underscores the MELD score as the premier predictor for short-term survival following TIPS. Meanwhile, the FIPS score and MELD-Na model exhibit potential in forecasting long-term outcomes. The study accentuates the significance of RAM selection for enhancing patient outcomes and advocates for additional research to corroborate these findings and fine-tune risk assessment in TIPS.

Transjugular intrahepatic portosystemic shunt (TIPS) is an established treatment for portal hypertension and its' complications in liver cirrhosis, yet the development of hepatic encephalopathy (HE) remains a significant concern. This review covers the reported incidence, risk factors, and management strategies for post-TIPS HE over the past decade. Incidence varies widely (7-61%), with factors like age, liver function, hyponatremia, and spontaneous portosystemic shunts influencing risk. Procedural aspects, including TIPS timing, indication, and stent characteristics, also contribute. Pharmacological prophylaxis with lactulose and rifaximin shows promise, but current evidence is inconclusive. Procedural preventive measures, such as shunt embolization and monitoring portal pressure gradients, are explored. Treatment involves pharmacological options like lactulose and rifaximin, and procedural interventions like stent diameter reduction. Ongoing studies on novel predictive markers and emerging treatments, such as faecal microbiota transplant, reflect the evolving landscape in post-TIPS HE management. This concise review provides clinicians with insights into the multifaceted nature of post-TIPS HE, aiding in improved risk assessment, prophylaxis, and management for patients undergoing TIPS procedures.

Standard of care for the treatment of ascites in cirrhosis is to administer a sodium-restricted diet and diuretic therapy. The progression of cirrhosis will eventually lead to the development of refractory ascites, at which point diuretics will no longer be able to control the ascites. Second-line therapies such as a transjugular intrahepatic portosystemic shunt (TIPS) placement or repeat large volume paracentesis are then required. There is some evidence that regular infusions of albumin may delay the onset of refractoriness and improve survival, especially if given at an early stage in the natural history of ascites and for a long enough duration. The use of TIPS can eliminate ascites, but its insertion is associated with complications, especially cardiac decompensation and worsening of hepatic encephalopathy. New information is now available regarding how to best select patients for TIPS, what type of cardiac investigations are needed and how under-dilating the TIPS at the time of insertion may help. The use of a non-absorbable antibiotics, such as rifaximin, starting in the pre-TIPS period may also reduce the likelihood of post-TIPS hepatic encephalopathy. In patients who are not suitable for TIPS, the use of an alfapump to remove the ascites via the bladder can improve quality of life without significantly altering survival. In the future it may be possible to use metabolomics to help refine the management of patients with ascites, e.g. to assess their response to non-selective beta-blockers or to predict the development of other complications such as acute kidney injury.

The selection of appropriate candidates for transjugular intrahepatic portosystemic shunt (TIPS) is important and challenging. To validate the Model for End-Stage Liver Disease (MELD) 3.0 in predicting mortality in patients with cirrhosis after TIPS creation.

A total of 855 consecutive patients with cirrhosis from December 2011 to October 2019 who underwent TIPS placement were retrospectively reviewed. The prognostic value of the MELD 3.0, MELD, MELD-Na, Child-Pugh and FIPS score was assessed using Harrell's C concordance index (c-index). The Hosmer-Lemeshow test was used to test the goodness of fit of all models and the calibration plot was drawn.

The c-index of the MELD 3.0 in predicting 3-month mortality was 0.727 (0.645-0.808), which were significantly superior to the MELD (0.663 [0.565-0.761]; P = 0.015), MELD-Na (0.672 [0.577-0.768]; P = 0.008) and FIPS (0.582 [0.477-0.687]; P = 0.015). The Child-Pugh score reached c-indices of 0.754 (0.673-0.835), 0.720 (0.649-0.792), 0.705 (0.643-0.766) and 0.665 (0.614-0.716) for 3-month, 6-month, 1-year, and 2-year mortality, respectively, which seems comparable to MELD 3.0. A MELD 3.0 of 14 could be used as a cut-off point for discriminating between high- and low-risk patients. The MELD 3.0 could stratify patients with Child-Pugh grade B (log-rank P < 0.001). The Child-Pugh score could stratify patients defined as low risk by MELD 3.0 (log-rank P < 0.001).

The MELD 3.0 was significantly superior to the MELD, MELD-Na and FIPS scores in predicting mortality in patients with cirrhosis after TIPS creation.

It is important and challenging to evaluate the survival of cirrhotic patients undergoing transjugular intrahepatic portosystemic shunt (TIPS). We aimed to validate the Freiburg index of post-TIPS survival (FIPS) score and classic scores for predicting mortality in Chinese patients after TIPS creation.

A total of 709 consecutive patients with cirrhosis from December 2011 to July 2018 who underwent TIPS placement were retrospectively reviewed. The prognostic value of the FIPS score, the model for end-stage liver disease (MELD) score, Child-Pugh score and Chronic Liver Failure Consortium Acute Decompensation score was validated with the receiver operating characteristic (ROC) curve and DeLong et al. test.

The MELD-Na score was superior to the FIPS score in predicting 1-month mortality [AUROC, 0.727 (0.692-0.759) vs. 0.588 (0.551-0.625); P = 0.048]. The MELD and MELD-Na scores were significant superior to the FIPS score in predicting 3-month mortality [AUROC, 0.730 (0.696-0.762) vs. 0.598 (0.561-0.634); P = 0.044 and 0.740 (0.706-0.772) vs. 0.598 (0.561-0.634); P = 0.028]. Subgroup analyses revealed that Child-Pugh score was better than FIPS score in predicting 3-month mortality [AUROC, 0.797 (0.745-0.843) vs. 0.578 (0.517-0.637); P = 0.049] in nonviral cirrhosis group.

Classic scores still had good risk stratification and predictive ability of post-TIPS mortality. The FIPS score was not superior to the classic scores in the current Chinese cohort. The MELD and MELD-Na scores were significantly superior to the FIPS score in predicting 3-month mortality.

The high risk for severe shunting-related post-interventional complications demands a stringent selection of candidates for transjugular intrahepatic portosystemic shunt (TIPS). We aimed to develop a simple and reliable tool to accurately predict early post-TIPS mortality.

144 cases of TIPS implantation were retrospectively analysed. Using univariate and multivariate Cox regression analysis of factors predicting mortality within 90 days after TIPS, a score integrating urea, international normalized ratio (INR) and bilirubin was developed. The Modified TIPS-Score (MOTS) ranges from 0 to 3 points: INR >1.6, urea >71 mg/dl and bilirubin >2.2 mg/dl account for one point each. Additionally, MOTS was tested in an external validation cohort (n = 187) and its performance was compared to existing models.

Modified TIPS-Score achieved a significant prognostic discrimination reflected by 90-day mortality of 8% in patients with MOTS 0-1 and 60% in patients with MOTS 2-3 (p < .001). Predictive performance (area under the curve) of MOTS was accurate (c = 0.845 [0.73-0.96], p < .001), also in patients with renal insufficiency (c = 0.830 [0.64-1.00], p = .02) and in patients with refractory ascites (c = 0.949 [0.88-1.00], p < .001), which are subgroups with particular room for improvement of post-TIPS mortality prediction. The results were reproducible in the validation cohort.

Modified TIPS-Score is a novel, practicable tool to predict post-TIPS mortality, that can significantly simplify clinical decision making. Its practical applicability should be further investigated.

BACKGROUND. Various prognostic scores for patients with chronic liver disease have been applied for predicting survival after TIPS placement. In 2021, the Freiburg index of post-TIPS survival (FIPS) score was developed specifically for predicting survival after TIPS placement. The score has exhibited variable performance in initial investigations conducted in German and U.S. cohorts. OBJECTIVE. The purpose of this study was to compare the utility of the FIPS score and traditional scoring systems for predicting post-TIPS survival in a cohort of Chinese patients with cirrhosis. METHODS. This retrospective validation study compared four prognostic scores (model for end-stage liver disease [MELD], sodium MELD [MELD-Na], Chronic Liver Failure Consortium acute decompensation [CLIF-C AD], and FIPS) in 383 patients (mean age, 54.9 ± 11.7 years; 249 men, 134 women) with cirrhosis who underwent TIPS placement (341 for variceal bleeding, 42 for refractory ascites) at Wuhan Union Hospital between January 2016 and August 2021. Model performance was assessed in terms of discrimination (using concordance index) and calibration (using Brier score and observed-to-predicted ratios) for 6-, 12-, and 24-month post-TIPS survival. Discrimination was further stratified by TIPS indication. Risk stratification was performed using previously proposed cutoffs for each score. RESULTS. During postprocedural follow-up, 72 (18.8%) patients died. Discriminative performance for 6-month survival was highest for FIPS score (concordance index, 0.784), followed by CLIF-C AD (0.743), MELD-Na (0.699), and MELD (0.694). FIPS score also showed the highest calibration in terms of lower Brier scores and observed-to-predicted ratios closer to 1 and showed the strongest prognostic performance for 12- and 24-month survival and in subgroups of patients who underwent TIPS placement for either variceal bleeding or refractory ascites (except for similar performance of FIPS and CLIF-C AD in the refractory ascites subgroup). When prior cutoffs were applied, further application of FIPS score was significantly associated with survival among patients classified as low risk by the other scores. CONCLUSION. FIPS score outperformed traditional risk scores in predicting post-TIPS survival in patients with cirrhosis. CLINICAL IMPACT. The findings support utility of FIPS score in differentiating patients who are optimal candidates for TIPS placement versus those at high risk who may instead warrant close monitoring and early liver transplant.

This review summarizes indications and contraindications for implantation of transjugular intrahepatic portosystemic shunt (TIPS). Further, patient selection strategies are discussed.

TIPS implantation is a highly effective treatment for portal hypertension. Main indications are ascites and variceal bleeding in patients with liver cirrhosis. There is growing evidence that early TIPS implantation after variceal bleeding is associated with an improved survival (preemptive TIPS).Preliminary data also suggest that an analogous concept of early TIPS implantation may be beneficial for patients with ascites. Further, well-selected patients with acute or chronic nonmalignant portal vein thrombosis can be effectively treated with TIPS implantation. In contrast, there is generally no recommendation for TIPS implantation in patients with hepatic veno-occlusive disease, noncirrhotic portal hypertension or prior before surgery to avoid complications of portal hypertension. Apart from evidence-based patient selection, the newly developed FIPS score can be an objective component in decision-making.

Consideration of well-established indications and contraindications for TIPS implantation as well as concise patient selection criteria are essential for an optimal outcome after TIPS implantation.
