Using transjugular intrahepatic portosystemic shunt as the first-line therapy in secondary prophylaxis of variceal hemorrhage

Evidence for preventing EVRB in cirrhotic patients: A systematic review

Systematic strategies for preventing and treating esophagogastric variceal rebleeding (EVRB) are currently inadequate. This systematic review aimed to update this critical gap by searching contemporary studies from major guideline websites, databases, and professional associations focused on EVRB prevention in cirrhosis patients. Key findings highlight evaluation methods, risk management, preventive measures, health education, and follow-up strategies. Notably, a hepatic venous pressure gradient exceeding 18 mmHg is identified as a reliable predictor of gastroesophageal varices (GOV) rebleeding. Effective management of primary diseases is crucial, with methods including antiviral and anti-fibrotic therapies, alcohol avoidance, vaccination, and careful medication management. The combination of nonselective β-blockers (NSBBs) and endoscopic variceal ligation (EVL) is established as the gold standard for secondary EVRB prevention. For patients experiencing recurrent bleeding despite NSBBs and EVL, transjugular intrahepatic portosystemic shunt (TIPS) therapy is recommended. Surgical options, such as surgical shunt and devascularization, are advised for those unsuitable for endoscopic therapy or TIPS, particularly in Child-Pugh A and B patients unresponsive to treatment. Additionally, traditional Chinese medicine options, such as Fufang Biejia Ruangan Tablets, Fuzheng Huayu Capsules, and Anluo Huaxian Pills, have shown promise in improving hepatic fibrosis and GOV in cirrhotic patients. This review offers a comprehensive overview of current prevention and treatment strategies for EVRB, providing valuable insights for clinicians and healthcare professionals.

Road to recompensation: Baveno VII criteria and transjugular intrahepatic portosystemic shunt in liver cirrhosis

Liver cirrhosis has long been considered a point of no return, with limited hope for recovery. However, recent advancements, particularly the Baveno VII criteria and the utilization of transjugular intrahepatic portosystemic shunt (TIPS), have illuminated the concept of hepatic recompensation. In this editorial we comment on the article by Gao et al published in the recent issue. This editorial provides a comprehensive overview of the evolution of understanding cirrhosis, the criteria for recompensation, and the efficacy of TIPS in achieving recompensation. We discuss key findings from recent studies, including the promising outcomes observed in patients who achieved recompensation post-TIPS insertion. While further research is needed to validate these findings and elucidate the mech-anisms underlying recompensation, the insights presented here offer renewed hope for patients with decompensated cirrhosis and highlight the potential of TIPS as a therapeutic option in their management.

Advancing hepatic recompensation: Baveno VII criteria and therapeutic innovations in liver cirrhosis management

The Baveno VII criteria redefine the management of decompensated liver cirrhosis, introducing the concept of hepatic recompensation marking a significant departure from the conventional view of irreversible decline. Central to this concept is addressing the underlying cause of cirrhosis through tailored therapies, including antivirals and lifestyle modifications. Studies on alcohol, hepatitis C virus, and hepatitis B virus-related cirrhosis demonstrate the efficacy of these interventions in improving liver function and patient outcomes. Transjugular intrahepatic portosystemic shunt (TIPS) emerges as a promising intervention, effectively resolving complications of portal hypertension and facilitating recompensation. However, optimal timing and patient selection for TIPS remain unresolved. Despite challenges, TIPS offers renewed hope for hepatic recompensation, marking a significant advancement in cirrhosis management. Further research is needed to refine its implementation and maximize its benefits. In conclusion, TIPS stands as a promising avenue for improving hepatic function and patient outcomes in decompensated liver cirrhosis within the framework of the Baveno VII criteria.

Azygoportal disconnection or a combination of non-selective beta-blockers and endoscopic variceal ligation to prevent recurrent bleeding in patients with cirrhosis awaiting transplantation

Objective: to compare the efficacy of azygoportal disconnection (APD) surgery and a combination between endoscopic variceal ligation (EVL) and non-selective beta-blockers (NSBBs) in the prevention of recurrent variceal bleeding (RVB). To compare the incidence of gastric variceal bleeding (GVB) after these manipulations in patients with decompensated cirrhosis waitlisted for liver transplantation (LTx).

Materials and methods. Patients with decompensated cirrhosis underwent RVB prophylaxis by APD surgery or by a combination of EVL and NSBBs.

Results. There were no significant differences in clinical, laboratory, demographic parameters, MELD-Na and Child–Turcotte–Pugh (CTP) scores, and frequencies of medium- and large-sized varicose veins among subgroups of patients with different RVB prophylaxis methods Patients with decompensated cirrhosis who underwent APD surgery did not experience any RVB episodes during the LTx waiting period, which lasted two years from the start of bleeding prophylaxis. In the same period, RVB occurred in 100% of cases in the EVL plus NSBBs group. Using the Kaplan–Meier method with the Log-Rank test, a significant difference (p = 0.0001) was found between the proportions of non-RVB patients in the APD and EVL + NSBBs groups. In the meantime, 48.1% of patients who had APD surgery developed GVB, while 100% of cases in EVL + NSBBs group did not. The Kaplan–Meier method with the Log-Rank test revealed a significant difference (p = 0.0001) between the proportion of non-GVB patients in EVL + NSBBs and APD groups.

Transjugular intrahepatic portosystemic shunt or a combination of nonselective beta blockers and endoscopic variceal ligation for prophylaxis of bleeding in waitlisted cirrhotic patients

Objective: to substantiate the choice of an optimal method of preventing and reducing the risk of variceal bleeding (VB) and cardia in patients with decompensated cirrhosis who have been enlisted for liver transplantation (LT).

Materials and methods. Patients with diuretic-resistant and diuretic-responsive ascites underwent prophylaxis for recurrent bleeding via transjugular intrahepatic portosystemic shunt (TIPS) or a combination of endoscopic variceal ligation (EVL) and nonselective beta-blockers (NSBB).

Results. Leukocyte counts, Na levels, and Child–Turcotte–Pugh (CTP) liver disease class in patients with diuretic-resistant ascites had significant differences when comparing individuals who received EVL + NSBB or underwent TIPS. In diuretic-responsive patients, there were significant differences for blood platelet count, albumin and Na levels, and CTP class when comparing EVL + NSBB and TIPS groups. In diuretic-resistant patients, incidence of grade 2 varices in EVL + NSBB group was significantly higher than in TIPS. Incidence of grade 3 varices was significantly higher in TIPS patients than in EVL + NSBB cohort. In diuretic-responsive patients, incidence of grade 2 and 3 varices had no significant differences when comparing these indicators in both groups. The proportion of patients with CTP class B was significantly higher both in diuretic-resistant and diuretic-responsive patients with various methods of rebleeding prophylaxis. The proportions of CTP class C patients with both forms of ascites were significantly higher in EVL + NSBB group than in TIPS. During the LT wait period within 2 years from the start of bleeding prophylaxis in diuretic-resistant patients, 78.4% of patients who underwent TIPS implantation developed recurrent bleeding, 100% of EVL + NSBB group within the same time frame, developed recurrent bleeding. Using the Kaplan–Meier estimate with the Log-Rank test, we were able to establish that there is a significant difference between the proportions of patients with recurrent VB in EVL + NSBB or TIPS groups with both forms of ascites.

Impressive recompensation in transjugular intrahepatic portosystemic shunt-treated individuals with complications of decompensated cirrhosis based on Baveno VII criteria

BACKGROUND

Transjugular intrahepatic portosystemic shunt (TIPS) is the standard second-line treatment option for individuals with complications of decompensated cirrhosis, such as variceal bleeding and refractory ascites.

AIM

To investigate whether recompensation existed in TIPS-treated patients with decompensated cirrhosis according to Baveno VII criteria.

METHODS

This retrospective analysis was performed on 64 patients who received TIPS for variceal bleeding or refractory ascites. The definition of recompensation referred to Baveno VII criteria and previous study. Clinical events, laboratory tests, and radiological examinations were regularly conducted during a preset follow-up period. The recompensation ratio in this cohort was calculated. Beyond that, univariate and multivariate regression models were conducted to identify the predictors of recompensation.

RESULTS

Of the 64 patients with a 12-mo follow-up, 20 (31%) achieved recompensation. Age [odds ratio (OR): 1.124; 95% confidence interval (CI): 1.034-1.222] and post-TIPS portal pressure gradient < 12 mmHg (OR: 0.119; 95%CI: 0.024-0.584) were identified as independent predictors of recompensation in patients with decompensated cirrhosis after TIPS.

CONCLUSION

The present study demonstrated that nearly one-third of the TIPS-treated patients achieved recompensation within this cohort. According to our findings, recompensation is more likely to be achieved in younger patients. In addition, postoperative portal pressure gradient reduction below 12 mmHg contributes to the occurrence of recompensation.

Outcomes of Transjugular Intrahepatic Portosystemic Shunt and Gastric Coronary Vein Embolization for Variceal Bleeding in Cirrhotic Portal Hypertension

Purpose: To evaluate the efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) combined with gastric coronary vein embolization (GCVE) for cirrhotic portal hypertensive variceal bleeding and compare outcomes of first-line with second-line treatment, coil with glue, and single-covered with double stents.Methods: Fifteen patients received TIPS plus GCVE as the first-line treatment for secondary prophylaxis of variceal bleeding, and 45 received it as second-line treatment. Preoperative and postoperative quantitative variables were compared using a paired t test. The incidence of survival rate, re-bleeding, hepatic encephalopathy, and shunt dysfunction were analyzed using the Kaplan-Meier method.Results: The portal venous pressure was significantly decreased from 39.0 ± 5.0 mm Hg to 22.5 ± 4.4 mm Hg (P≤0.001) after TIPS treatment. After 1, 3, 6, 12, 18, and 24 months re-bleeding rates were 1.6%, 3.3%, 6.6%, 13.3%, 0%, and 0%, respectively. Shunt dysfunction rates were 5%, 0%, 10%, 16.6%, 1.6%, and 5%, respectively. Hepatic encephalopathy rates were 3.3%, 1.6%, 3.3%, 6.6%, 0%, and 0%, respectively. And survival rates were 100%, 100%, 100%, 96.6%, 93.3%, and 88.3% respectively. In comparative analysis, statistically significant differences were seen in re-bleeding between the first-line and second-line treatment groups (26.6% vs 24.4%, log-rank P=0.012), and survival rates between single-covered and double stent (3.7% vs 16.1%, log-rang (P=0.043).Conclusion: The results suggest that TIPS combined with GCVE is effective and safer in the treatment of cirrhotic portal hypertensive variceal bleeding. The use of TIP plus GCVE as first-line treatment, may be preferable for high-risk re-bleeding, and more than 25 mm Hg portal venous pressure with repeated variceal bleeding. However, the sample size was small. Therefore, large, randomized, controlled, multidisciplinary center studies are needed for further evaluation.

The impact of thrombocytopenia on variceal bleeding in cirrhotic patients with transjugular intrahepatic portosystemic shunt

Thrombocytopenia is the most frequent haematologic disorder in patients with cirrhosis, and it is perceived as a contributory factor for bleeding events. Cirrhosis patients with portal hypertension (PHT) is often accompanied with mild to moderate thrombocytopenia when they treated with transjugular intrahepatic portosystemic shunt (TIPS). To address whether the risk of variceal hemorrhage after TIPS varies with different platelet count in patients with normal platelet count and thrombocytopenia, we conducted the retrospective controlled study to evaluate the association of platelet count with the risk of variceal bleeding after TIPS. 304 patients were selected to the study. Propensity score matching was performed to adjust for potential selection bias. 63 patients from each group could be paired. Cox proportional hazards models were used to evaluate the association between platelet and variceal bleeding after TIPS. Platelet counts of two groups are 185.0 ± 98.7 × 10⁹/L (normal platelet count) and 70.6 ± 39.3 × 10⁹/L (thrombocytopenia) respectively. The bleeding rates of two groups in overall cohort are 10.9% (normal platelet count) and 12.9% (thrombocytopenia). After matched, the bleeding rates of two groups are 11.1% (normal platelet count) and 14.3% (thrombocytopenia) There was no statistically significant difference in bleeding rates between the two groups, either in the whole cohort (P = 0.671) or in the matched cohort (P = 0.593). Platelet count was not associated with bleeding events after TIPS (hazard ratio (HR) 95% confidence interval: 0.986-1.005, P = 0.397 in normal platelet count and 95% confidence interval: 0.968-1.020, P = 0.648 in thrombocytopenia). Thrombocytopenia in patients with cirrhosis was not associated with the risk of variceal bleeding episodes post-TIPS. Thrombocytopenia should not be viewed as an absolute contraindication for TIPS.

A new choice of stent for transjugular intrahepatic portosystemic shunt creation: Viabahn ePTFE covered stent/bare metal stent combination

Objectives

To compare the clinical outcomes in terms of structure and function between the insertion of a transjugular intrahepatic portosystemic shunt (TIPS) created with the Viabahn ePTFE covered stent/bare metal stent (BMS) combination and the Fluency ePTFE covered stent/BMS combination.

Methods

A total of 101 consecutive patients who received a TIPS from February 2016 to August 2018 in our center were retrospectively analyzed. Sixty-four subjects were enrolled in the Viabahn group and 37 were enrolled in the Fluency group. The geometry characteristics of the TIPS were calculated, and the associated occurrence of shunt dysfunction, survival, overt hepatic encephalopathy, and variceal rebleeding were evaluated.

Results

The technical success rate was 100%. After the insertion of the TIPS, the rate of shunt dysfunction during the first 3 months was significantly different between the Viabahn and Fluency groups (1.6% and 13.5%, respectively; p ​= ​0.024). Multivariate analysis indicated that the angle of portal venous inflow (α) was the only independent risk factor for shunt dysfunction (hazard ratio ​= ​1.060, 95% confidence interval ​= ​1.009–1.112, p ​= ​0.020). In addition, 3 months after the TIPS insertion, the α angle distinctly increased from 20.9° ​± ​14.3°–26.9° ​± ​20.1° (p ​= ​0.005) in the Fluency group but did not change significantly in the Viabahn group (from 21.9° ​± ​15.1°–22.9° ​± ​17.6°, p ​= ​0.798).

Conclusions

Shunt dysfunction was related to the α angle owing to the slight effect on the α angle after the implantation of the TIPS. The Viabahn ePTFE covered stent/BMS combination was more stable in structure and promised higher short-term stent patency compared with the Fluency ePTFE covered stent/BMS combination.

Effect of splenectomy on the outcomes in patients with cirrhosis receiving transjugular intrahepatic portosystemic shunt

BACKGROUND AND AIM

Patients indicated to transjugular intrahepatic portosystemic shunt (TIPS) placement may have splenectomy history due to thrombocytopenia. This study aimed to evaluate the effect of prior splenectomy on TIPS procedure and post-TIPS outcomes.

METHODS

We conducted a longitudinal analysis based on a cohort of 284 patients with cirrhosis submitted to TIPS; 74 patients had splenectomy history (splenectomy group) and 210 did not (non-splenectomy group). Cox proportional hazards models were used to evaluate the association between splenectomy and outcomes after TIPS. The primary outcome was shunt dysfunction. Secondary outcomes included all-cause mortality, clinical recurrence of bleeding or ascites, and overt hepatic encephalopathy (OHE).

RESULTS

During a median follow-up of 16.2 months, the splenectomy group had significantly lower rates of postoperative shunt patency (85.5% vs 95.6% at 1 year and 75.2% vs 86.5% at 2 years; adjusted hazard ratio [HR] 2.53; 95% confidence interval [CI] 1.21-5.12; P = 0.01) and higher risk of OHE (adjusted HR 1.82; 95% CI 1.03-3.54; P = 0.04). But the risk of mortality (adjusted HR 0.87; 95% CI 0.41-1.87; P = 0.73) and recurrent bleeding or ascites (adjusted HR 1.17; 95% CI 0.53-2.35; P = 0.77) showed no statistical difference. Multivariate analysis confirmed splenectomy history and endoscopic therapy as independent predictors of shunt dysfunction. Besides, pre-TIPS splenectomy increased the difficulty of TIPS procedure by complicating portal vein puncture.

CONCLUSIONS

For patients with cirrhosis submitted to TIPS, prior splenectomy complicated TIPS procedure and increased the risk of shunt dysfunction and OHE after TIPS, but was not significantly associated with the occurrence of mortality and recurrent bleeding or ascites.

Transjugular intrahepatic portosystemic shunt (TIPS) as rescue therapy for endoscopic glue migration and bleeding gastric varices

Gastric variceal (GV) bleeding is an important and fatal complication for cirrhotic patients which has historically been controlled with sclerosants and band ligation. Cyanoacrylate glue therapy has emerged as a more favorable option with bleeding control of up to 90% and low complication rates; however, several reports show possible ectopic systemic glue migration, most commonly into the portomesenteric system and leading to portal hypertension. To decompress portal pressures and mitigate future complications, transjugular intrahepatic portosystemic shunt (TIPS) placement may be a viable rescue therapy. We present two cases of TIPS placement for an 18-year-old and 51-year-old male in the setting of endoscopic glue migration into the portomesenteric system that demonstrate feasibility and success in temporizing acute variceal bleeding. Both cases demonstrated decompressing portovenous pressures but may result in need for re-intervention.
