Transjugular intrahepatic portosystemic stent-shunt in the management of portal hypertension
These guidelines on transjugular intrahepatic portosystemic stent-shunt (TIPSS) in the management of portal hypertension have been commissioned by the Clinical Services and Standards Committee (CSSC) of the British Society of Gastroenterology (BSG) under the auspices of the Liver Section of the BSG. The guidelines are new and have been produced in collaboration with the British Society of Interventional Radiology (BSIR) and British Association of the Study of the Liver (BASL). The guidelines development group comprises elected members of the BSG Liver Section, representation from BASL, a nursing representative and two patient representatives. The quality of evidence and grading of recommendations was appraised using the GRADE system. These guidelines are aimed at healthcare professionals considering referring a patient for a TIPSS. They comprise the following subheadings: indications; patient selection; procedural details; complications; and research agenda. They are not designed to address: the management of the underlying liver disease; the role of TIPSS in children; or complex technical and procedural aspects of TIPSS.
Covered TIPS versus endoscopic band ligation plus propranolol for the prevention of variceal rebleeding in cirrhotic patients with portal vein thrombosis: a randomised controlled trial
ObjectiveLimited data are available on the prevention of variceal rebleeding in cirrhotic patients with portal vein thrombosis (PVT). This study aimed to compare transjugular intrahepatic portosystemic shunt (TIPS) with covered stents versus endoscopic band ligation (EBL) plus propranolol for the prevention of variceal rebleeding among patients with cirrhosis and PVT.DesignConsecutive cirrhotic patients (94% Child-Pugh class A or B) with PVT who had variceal bleeding in the past 6 weeks were randomly assigned to TIPS group (n=24) or EBL plus propranolol group (EBL+drug, n=25), respectively. Primary endpoint was variceal rebleeding. Secondary endpoints included survival, overt hepatic encephalopathy (OHE), portal vein recanalisation and rethrombosis, other complications of portal hypertension and adverse events.ResultsDuring a median follow-up of 30 months in both groups, variceal rebleeding was significantly less frequent in the TIPS group (15% vs 45% at 1 year and 25% vs 50% at 2 years, respectively; HR=0.28, 95% CI 0.10 to 0.76, p=0.008), with a significantly higher portal vein recanalisation rate (95% vs 70%; p=0.03) and a relatively lower rethrombosis rate (5% vs 33%; p=0.06) compared with the EBL+drug group. There were no statistically significant differences in survival (67% vs 84%; p=0.152), OHE (25% vs 16%; p=0.440), other complications of portal hypertension and adverse events between groups.ConclusionCovered TIPS placement in patients with PVT and moderately decompensated cirrhosis was more effective than EBL combined with propranolol for the prevention of rebleeding, with a higher probability of PVT resolution without increasing the risk of OHE and adverse effects, but this benefit did not translate into improved survival.Trial registration numberClinicalTrials.gov: NCT01326949.
Transjugular intrahepatic portosystemic shunt (TIPS): current indications and strategies to improve the outcomes
Transjugular intrahepatic portosystemic shunt (TIPS) represents a very effective treatment of complications of portal hypertension. Established indications to TIPS in cirrhotic patients include portal hypertensive bleeding and refractory ascites. Over the years additional indications have been proposed, such as the treatment of vascular disease of the liver, hepatic hydrothorax, hepatorenal syndrome and bleeding from ectopic varices. Indications under evaluation include treatment of portal hypertension prior to major abdominal surgery and treatment of portal vein thrombosis. In spite of these advances, there are still uncertainties regarding the appropriate workup for patients to be scheduled for TIPS. Moreover, prevention and management of post-TIPS complications including hepatic encephalopathy and heart failure are still suboptimal. These issues are particularly relevant considering aging in TIPS candidates in Western countries. Correct selection of patients is mandatory to prevent complications which may eventually frustrate the good hemodynamic results and worsen the patient’s quality of life or even life expectancy. The possible role of small diameter TIPS to prevent post-procedural complications is discussed.
A Meta-analysis on Interventional Metrics of Transjugular Intrahepatic Portosystemic Shunt Placement With Cone-beam Computed Tomography Guidance and Fluoroscopy Guidance
To integrate the results of studies on interventional metrics of cone-beam computed-tomography (CBCT) guidance and fluoroscopy guidance in transjugular intrahepatic portosystemic shunt (TIPS) placement in a meta-analysis. A systemic literature search was conducted in PubMed, Ovid/Medline, Cumulative Index to Nursing and Allied Health Literature, Web of Science and Google Scholar. Inclusion criteria were original research articles in English, comparison of CBCT and fluoroscopy guided TIPS placements and reporting of outcome parameters (procedure time, fluorotime, radiation exposure). Study quality was assessed by modified Downs-and-Black checklist. Heterogeneity was evaluated using forest plots, I , and considering study differences. A meta-analysis was conducted to combine the outcome effect using mean difference (MD) between CBCT and fluoroscopy guided TIPS placements. In this meta-analysis, five studies with 218 patients and TIPS placements were included. Study quality was limited with 12±0 points for procedure time, fluorotime and dose area product (DAP). Heterogeneity was indicated in procedure time (I =48.7%), fluorotime (I =44.2%) and DAP (I =55.4%). By application of random-effects model, procedure time and fluorotime of TIPS placements were not significantly different between CBCT and fluoroscopy guidance with an overall MD of -14.43min [95% confidence interval (CI)=-38.82 to 9.97 min; =0.16] and -6.23 min (95% CI=-22.27 to 9.80 min; =0.24). DAP was not significant between TIPS placement under CBCT and fluoroscopy guidance with a MD of 27.44 Gy*cm (95% CI=-10.47 to 65.34 Gy*cm ; =0.11). CBCT guidance tends to accelerate fluoroscopy and procedure times with slightly elevated DAP compared to fluoroscopy guidance in TIPS placements. Evidence is limited by the small number of feasibility studies. Further investigations need standardized reporting, especially for procedural complications and shunt patency.
Challenges and Opportunities in the Adoption of p-TIPS for Acute Variceal Bleeding: Insights from a US Tertiary Center
Background and AimsSince the overwhelmingly positive results of the ‘early use of TIPS’ published in 2010, studies in Europe and Asia have confirmed early/pre-emptive transjugular intrahepatic portosystemic shunt (p-TIPS) in high-risk patients with acute variceal bleed (AVB) reduces treatment failure and mortality compared to standard of care (SOC). There are no studies evaluating p-TIPS in a US cohort.MethodsA review of patients with cirrhosis from June 2010 to June 2020 with AVB was conducted from a single large US center.ResultsOf 745 cirrhotic patients with AVB, 18% met criteria for p-TIPS. Alcohol and HCV accounted for 75% of etiology; 13% MASLD. The mean MELD-Na score in our cohort was 24, which is ten points higher than reported in the literature for over 600 p-TIPS cases. Only 9 patients underwent p-TIPS. Patients undergoing p-TIPS were less likely to have MASLD, more likely to be female and less likely to have PSE at baseline. One-year mortality in the SOC group (including patients undergoing ‘rescue TIPS’) was 53% versus 0% for p-TIPS (p = 0.01).ConclusionOur observation suggests hesitancy among providers to recommend p-TIPS, likely due to concerns regarding a ‘sicker’ patient population. The current SOC in high-risk patients remain suboptimal. Limited data, including our own, suggest that p-TIPS may confer a survival benefit even in patients with high MELD. However, the recommendation of p-TIPS in such patients necessitates validation of its safety and efficacy. Consequently, we advocate for a RCT in the US to conclusively assess the utility of p-TIPS in this context. Until such evidence is established, it is likely that underutilization of this life-saving intervention will persist.
6-mm shunt transjugular intrahepatic portosystemic shunt in patients with severe liver atrophy and variceal bleeding
Objectives We proposed a strategy for the creation of a 6-mm transjugular intrahepatic portosystemic shunt (TIPS) and to assess its effectiveness compared to a conventional 8-mm shunt for TIPS-induced hepatic encephalopathy (HE). Methods Patients were reviewed retrospectively using propensity score matching (1:1) and divided into 6-mm and 8-mm shunt groups based on shunt diameter. The stent patency, HE incidence, and rebleeding rate between the two groups were then compared. Results From January 2018 to June 2021, both 6-mm shunt group and 8-mm shunt group included 58 patients. The 6-mm shunt group had significantly smaller liver volumes (879.3 ± 237.1 vs. 1008.8 ± 293.0; p  = 0.010), and the median stent patency times were 30.7 and 33.8 months in the 6-mm and 8-mm groups, respectively ( p  = 0.124). No statistically significant difference was found between the two groups in the 1-year (8.6% vs. 3.4%; p  = 0.242) and 2-year (17.2% vs. 12.1%; p  = 0.242) rebleeding rates. The 1-year cumulative incidences of overt HE were 12.1% and 27.6% in the 6-mm and 8-mm groups, respectively ( p  = 0.040), and the 2-year cumulative overt HE incidences in these groups were 19.0% and 36.2%, respectively ( p  = 0.038). Notably, patients with a 6-mm shunt also experienced less hepatic impairment. Conclusions For patients with variceal bleeding and a small liver volume, the 6-mm shunt significantly reduced the incidence of overt HE, protected perioperative liver function, and did not affect stent patency or rebleeding rate. Clinical relevance statement For patients with variceal bleeding with small liver volume, the 6-mm transjugular intrahepatic portosystemic shunt (TIPS) significantly reduced the incidence of overt hepatic encephalopathy after TIPS, protected perioperative liver function, and did not affect stent patency and rebleeding rate. Key Points. • A strategy for the creation of a 6-mm transjugular intrahepatic portosystemic shunt for patients with variceal bleeding and a small liver volume was proposed. • The 6-mm transjugular intrahepatic portosystemic shunt significantly reduced the incidence of overt hepatic encephalopathy. • The 6-mm transjugular intrahepatic portosystemic shunt did not affect stent patency or rebleeding rate.
Comparison of specialized stent versus generic stent and bare stent combination for transjugular intrahepatic portosystemic shunt creation
Transjugular intrahepatic portosystemic shunt (TIPS) creation using the Viatorr stent remains relatively uncommon in underdeveloped and high-burden disease regions in Asia–Pacific, and there is a lack of comparative studies regarding its prognostic effects compared with the generic stent-graft/bare stent combination. The purpose of this retrospective study is to compare the prognostic endpoints of these two treatments in patients who underwent TIPS creation. Clinical data from 145 patients were collected, including 82 in the combination group and 63 in the Viatorr group. Differences in prognostic endpoints (shunt dysfunction, death, overt hepatic encephalopathy [OHE], rebleeding) between the two groups were analyzed using Kaplan–Meier curves. The Cox proportional hazards model was used to identify independent risk factors for post-TIPS shunt dysfunction. The TIPS procedure was successful in all patients. After TIPS creation, both groups showed a significant decrease in porto-caval pressure gradient compared to that before TIPS creation. The stent patency rates at 6, 12, and 18 months were high in both the combination and Viatorr groups (93.7%, 88.5%, and 88.5% vs. 96.7%, 93.4%, and 93.4%, respectively). The stent patency rates was higher in the combination group than in the Viatorr group, although not statistically significant (HR = 2.105, 95% CI 0.640–6.922, Log-rank P  = 0.259). There were no significant differences in other prognostic endpoints (death, OHE, rebleeding) between the two groups. The Cox model identified portal vein diameter (HR = 0.807, 95% CI 0.658–0.990, P  = 0.040) and portal vein thrombosis (HR = 13.617, 95% CI 1.475–125.678, P  = 0.021) as independent risk factors for post-TIPS shunt dysfunction. The shunt patency rates between the Viatorr stent and the generic stent-graft/bare stent combination showed no significant difference and the generic stent-graft/bare stent combination may be a viable alternative in areas where the Viatorr stent is not yet available.
Predictors of Occurrence and Risk of Hepatic Encephalopathy After TIPS Creation: A 15-Year Experience
PurposeTo identify clinical variables, including use of newer Viatorr TIPS endoprosthesis with controlled expansion (VCX) that may affect the occurrence and risk of hepatic encephalopathy after transjugular intrahepatic portosystemic shunt (TIPS) creation.MethodsA total of 376 patients who underwent TIPS creation at our institution between 2003 and 2018 were retrospectively identified. Of these patients, 71 received a Viatorr controlled expansion endoprosthesis and 305 received a Viatorr TIPS endoprosthesis (older version without controlled expansion). Multivariate regression analysis was used to identify factors predicting the occurrence of hepatic encephalopathy after TIPS creation; a Cox proportional hazard model was used to assess risk of HE through time to HE onsetResultsA total of 194 patients (52%) developed hepatic encephalopathy after TIPS creation, including 28 of 71 patients (39%) who received a VCX endoprosthesis. Older patient age and the use of Viatorr endoprosthesis without controlled expansion were significantly associated with the development of hepatic encephalopathy overall. Pre-TIPS pressure variables, patient age, plasma international normalized ratio, and model for end-stage liver disease score were risk factors for time to hepatic encephalopathy.ConclusionSeveral variables are mild predictors of early hepatic encephalopathy development after TIPS creation, and the use of VCX endoprosthesis in TIPS creation is associated with a modest lower risk of hepatic encephalopathy. These preliminary findings should be considered in regard to patient selection, endoprosthesis selection, and post-transjugular intrahepatic portosystemic shunt creation monitoring for the development of hepatic encephalopathy.
Early implantation of a transjugular intrahepatic portosystemic shunt (TIPS) in patients with liver cirrhosis and ascites (eTIPS): a multicentre, randomised controlled trial
Background Portal hypertension is a major complication in patients with liver cirrhosis, leading to severe outcomes such as variceal bleeding and ascites. Transjugular intrahepatic portosystemic shunt (TIPS) has emerged as an effective interventional treatment of recurrent ascites and variceal bleeding. However, up to 30% of patients with recurrent ascites show TIPS refractory ascites, and prior data have shown that the frequency of paracenteses before TIPS implantation predicts ascites clearance indicating that TIPS implantation may be too late in some patients. Especially, patients with grade 2 ascites and a MELD score ≥ 15, or grade 3 ascites irrespective of MELD score at first decompensation with ascites face a high risk of further decompensation and mortality. Therefore, these patients may benefit from early TIPS implantation in order to improve post-TIPS mortality. We hypothesise that early TIPS implantation in these selected patients at the time of the first decompensation may improve transplantation-free survival compared to standard medical treatment (SMT). Methods The eTIPS study is a prospective, randomised, open, multicenter interventional, superiority trial. Patients will be randomised 1:1 in the intervention group with TIPS implantation and in the SMT group. The primary endpoint is transplantation-free survival. Secondary endpoints include the time to ascites with need for paracentesis and quality of life assessed six and 12 months after randomisation. Discussion Expanding the concept of early TIPS implantation to ascites management may offer significant survival benefits and may significantly change the treatment algorithm of patients with ascites.

Anticoagulation and Transjugular Intrahepatic Portosystemic Shunt for the Management of Portal Vein Thrombosis in Cirrhosis: A Prospective Observational Study
Current guidelines recommend anticoagulation as the mainstay of portal vein thrombosis (PVT) treatment in cirrhosis. However, because of the heterogeneity of PVT, anticoagulation alone does not always achieve satisfactory results. This study aimed to prospectively evaluate an individualized management algorithm using a wait-and-see strategy (i.e., no treatment), anticoagulation, and transjugular intrahepatic portosystemic shunt (TIPS) to treat PVT in cirrhosis. Between February 2014 and June 2018, 396 consecutive patients with cirrhosis with nonmalignant PVT were prospectively included in a tertiary care center, of which 48 patients (12.1%) were untreated, 63 patients (15.9%) underwent anticoagulation, 88 patients (22.2%) underwent TIPS, and 197 patients (49.8%) received TIPS plus post-TIPS anticoagulation. The decision of treatment option mainly depends on the stage of liver disease (symptomatic portal hypertension or not) and degree and extension of thrombus. During a median 31.7 months of follow-up period, 312 patients (81.3%) achieved partial (n = 25) or complete (n = 287) recanalization, with 9 (3.1%) having rethrombosis, 64 patients (16.2%) developed major bleeding (anticoagulation-related bleeding in 7 [1.8%]), 88 patients (22.2%) developed overt hepatic encephalopathy, and 100 patients (25.3%) died. In multivariate competing risk regression models, TIPS and anticoagulation were associated with a higher probability of recanalization. Long-term anticoagulation using enoxaparin or rivaroxaban rather than warfarin was associated with a decreased risk of rethrombosis and an improved survival, without increasing the risk of bleeding. However, the presence of complete superior mesenteric vein thrombosis was associated with a lower recanalization rate, increased risk of major bleeding, and poor prognosis. In patients with cirrhosis with PVT, the individualized treatment algorithm achieves a high-probability recanalization, with low rates of portal hypertensive complications and adverse events.
