Objective: To compare the safety and efficacy of transmesenteric vein extrahepatic portosystemic shunt (TEPS) and transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of cavernous transformation of the portal vein (CTPV). Methods: The clinical data of CTPV patients with patency or partial patency of the superior mesenteric vein treated with TIPS or TEPS treatment in the Department of Vascular Surgery of Henan Provincial People's Hospital from January 2019 to December 2021 were selected. The differences in baseline data, surgical success rate, complication rate, incidence rate of hepatic encephalopathy, and other related indicators between TIPS and TEPS group were statistically analyzed by independent sample t-test, Mann-Whitney U test, and Chi-square test. Kaplan-Meier survival curve was used to calculate the cumulative patency rate of the shunt and the recurrence rate of postoperative portal hypertension symptoms in both groups. Results: The surgical success rate (100% vs. 65.52%), surgical complication rate (6.67% vs. 36.84%), cumulative shunt patency rate (100% vs. 70.70%), and cumulative symptom recurrence rate (0% vs. 25.71%) of the TEPS group and TIPS group were statistically significantly different (P < 0.05). The time of establishing the shunt [28 (2141) min vs. 82 (51206) min], the number of stents used [1 (12) vs. 2 (15)], and the length of the shunt [10 (912) cm vs. 16 (1220) cm] were statistically significant between the two groups (t = -3.764, -4.059, -1.765, P < 0.05). The incidence of postoperative hepatic encephalopathy in the TEPS group and TIPS group was 6.67% and 15.79% respectively, with no statistically significant difference (Fisher's exact probability method, P = 0.613). The pressure of superior mesenteric vein decreased from (29.33 ± 1.99) mmHg to (14.60 ± 2.80) mmHg in the TEPS group and from (29.68 ± 2.31) mmHg to (15.79 ± 3.01) mmHg in TIPS group after surgery, and the difference was statistically significant (t = 16.625, 15.959, P < 0.01). Conclusion: The best indication of TEPS is in CTPV patients with patency or partial patency of the superior mesenteric vein. TEPS improves the accuracy and success rate of surgery and reduces the incidence of complications.

Objective: To investigate the factors influencing total bilirubin elevation and its correlation with UGT1A1 gene polymorphism in the early postoperative period of transjugular intrahepatic portosystemic shunt (TIPS). Methods: 104 cases with portal hypertension and esophageal variceal hemorrhage (EVB) treated with elective TIPS treatment were selected as the study subjects and were divided into a bilirubin-elevated group and a normal bilirubin group according to the total bilirubin elevation level during the early postoperative period. Univariate analysis and logistic regression were used to analyze the factors influencing total bilirubin elevation in the early postoperative period. PCR amplification and first-generation sequencing technology were used to detect the polymorphic loci of the UGT1A1 gene promoter TATA box, enhancer c.-3279 T > G, c.211G > A, and c.686C > A. Logistic regression was used to analyze the correlation of four locus alleles and genotypes with elevated total bilirubin in the early postoperative period. Results: Among the 104 cases, 47 patients were in the bilirubin elevated group, including 35 males (74.5%) and 12 females (25.5%), aged (50.72 ± 12.56) years. There were 57 cases in the normal bilirubin group, including 42 males (73.7%) and 15 females (26.3%), aged (51.63 ± 11.10) years. There was no statistically significant difference in age (t = -0.391, P = 0.697) and gender (χ(2) = 0.008, P = 0.928) between the two groups of patients. Univariate analysis revealed that preoperative alanine transaminase (ALT) level (χ(2) = 5.954, P = 0.015), total bilirubin level (χ(2) = 16.638, P < 0.001), MELD score (χ(2) = 10.054, P = 0.018), Child-Pugh score (χ(2) = 6.844, P = 0.022), and postoperative portal vein branch development (χ(2) = 6.738, P = 0.034) were statistically significantly different between the two groups. Logistic regression analysis showed that preoperative ALT level, total bilirubin level, and portal vein branch development after TIPS were correlated with the elevated total bilirubin in the early postoperative period. The polymorphism of the c.211G > A locus of the UGT1A1 gene correlation had elevated total bilirubin in the early postoperative period of TIPS. The risk of elevated total bilirubin was increased in the population carrying allele A (P = 0.001, OR = 4.049) in the early postoperative period. Allelic polymorphisms in the TATA box promoter region and enhancer c.-3279 T > G and c.686C > A had no statistically significant difference between the bilirubin-elevated group and the normal bilirubin group. Conclusion: The preoperative ALT level, total bilirubin level, and portal vein branch development are correlated with the elevated total bilirubin in early postoperative patients. The polymorphisms of the UGT1A1 gene and enhancer c.211G > A are correlated with the occurrence of elevated total bilirubin in the early postoperative period of TIPS. Allele A carrier may have a higher risk of elevated total bilirubin in the early postoperative period.

Objective: To investigate the effects of plasma lipopolysaccharide (LPS) concentration changes on platelet release of vascular endothelial growth factor (VEGF) and thrombospondin (TSP)-1 in patients with decompensated cirrhotic portal hypertension after transjugular intrahepatic portosystemic shunt (TIPS) procedure. Methods: 169 cases with cirrhotic portal hypertension were enrolled, of which 81 cases received TIPS treatment. LPS, VEGF, and TSP-1 concentrations with different Child-Pugh class in peripheral blood plasma of patients were measured. After pre-incubation of normal human platelets with different concentrations of LPS and stimulated by collagen in vitro, platelet PAC-1 expression rate, VEGF, and TSP-1 concentrations were detected. PAC-1 expression rate and the concentrations of LPS, VEGF and TSP-1 in peripheral blood plasma of patients before and after TIPS procedure were detected. The relationship between plasma LPS, VEGF and TSP-1 concentrations and Child-Pugh score changes in patients after TIPS procedure was analyzed. Statistical analysis was performed by t-test, one-way ANOVA or Pearson's rho according to different data. Results: Plasma LPS and TSP-1 concentrations were significantly higher in Child-Pugh class C patients than class A and B, but the concentration of plasma VEGF was significantly lower than class A and B (P < 0.01). In vitro experiments showed that concentration of LPS, TSP-1, and platelet PAC-1 expression rate was higher in the supernatant, but the difference in the concentration of VEGF in the supernatant was not statistically significant. Portal vein pressure and platelet activation were significantly decreased (P < 0.01) in patients after TIPS procedure. Portal venous pressure, platelet activation, plasma LPS, and TSP-1 levels were significantly decreased continuously, while VEGF levels were significantly increased continuously after TIPS procedure. Plasma LPS concentration was positively correlated with TSP-1 concentration (r = 0.506, P < 0.001), and negatively correlated with VEGF concentration (r = -0.167, P = 0.010). Child-Pugh score change range was negatively correlated with change range of plasma VEGF concentration (r = -0.297, P = 0.016), and positively correlated with change range of plasma TSP-1 concentration (r = 0.145, P = 0.031) after TIPS. Conclusion: Portal venous pressure gradient, plasma LPS concentration and corresponding platelet activation was decreased in cirrhotic portal hypertension after TIPS procedure, and with TSP-1 reduction and VEGF elevation it is possible to reduce the liver function injury caused by portal venous shunt.

BACKGROUND: Portosystemic shunts, including surgical portosystemic shunts and transjugular intra-hepatic portosystemic shunt (TIPS), may have benefit over endoscopic therapy (ET) for treatment of variceal bleeding in patients with cirrhotic portal hypertension; however, whether there being a survival benefit among them remains unclear. This study was to compare the effect of three above-mentioned therapies on the short-term and long-term survival in patient with cirrhosis. METHODS: Using the terms "variceal hemorrhage or variceal bleeding or variceal re-bleeding" OR "esophageal and gastric varices" OR "portal hypertension" and "liver cirrhosis," the Cochrane Central Register of Controlled Trials, PubMed, Embase, and the references of identified trials were searched for human randomized controlled trials (RCTs) published in any language with full texts or abstracts (last search June 2017). Risk ratio (RR) estimates with 95% confidence interval (CI) were calculated using random effects model by Review Manager. The quality of the included studies was evaluated using the Cochrane Collaboration's tool for the assessment of the risk of bias. RESULTS: Twenty-six publications comprising 28 RCTs were included in this analysis. These studies included a total of 2845 patients: 496 (4 RCTs) underwent either surgical portosystemic shunts or TIPS, 1244 (9 RCTs) underwent either surgical portosystemic shunts or ET, and 1105 (15 RCTs) underwent either TIPS or ET. There was no significant difference in overall mortality and 30-day or 6-week survival among three interventions. Compared with TIPS and ET, separately, surgical portosystemic shunts were both associated with a lower bleeding-related mortality (RR = 0.07, 95% CI = 0.01-0.32; P < 0.001; RR = 0.17, 95% CI = 0.06-0.51, P < 0.005) and rate of variceal re-bleeding (RR = 0.23, 95% CI = 0.10-0.51, P < 0.001; RR = 0.10, 95% CI = 0.04-0.24, P < 0.001), without a significant difference in the rate of postoperative hepatic encephalopathy (RR = 0.52, 95% CI = 0.25-1.00, P = 0.14; RR = 1.09, 95% CI = 0.59-2.01, P = 0.78). TIPS showed a trend toward lower variceal re-bleeding (RR = 0.46, 95% CI = 0.36-0.58, P < 0.001), but a higher incidence of hepatic encephalopathy than ET (RR = 1.78, 95% CI = 1.34-2.36, P < 0.001). CONCLUSIONS The overall analysis revealed that there seem to be no short-term and long-term survival advantage, but surgical portosystemic shunts are with the lowest bleeding-related mortality among the three therapies. Surgical portosystemic shunts may be the most effective without an increased risk of hepatic encephalopathy and TIPS is superior to ET but at the cost of a higher incidence of hepatic encephalopathy. However, some of findings should be interpreted with caution due to the lower level of evidence and the existence of significant heterogeneity.

Portal hypertension(PH) is one of the main complications of cirrhosis.Transjugular intrahepatic portosystemic shunt(TIPS) is the percutaneous creation of a conduit from the hepatic vein to the portal vein that is used to manage consequences of PH (i.e., variceal bleeding and refractory ascites) and used as a bridging therapy to liver transplant for decompensated cirrhosis. The following Clinical Practice Guidelines (CPGs) presents profession associational recommendations of the Chinese College of Interventionalists(CCI) on TIPS for PH. The CPGs was written by more than 30 experts in the field of TIPS in China (including interventional radiologists, liver surgeons, hepatologists and gastroenterologist, et al.). The panel of experts, produced these CPGs using evidence from PubMed and Cochrane database searches and combined with relevant expert consensuses and high quality clinical researches in China providing up to date guidance on TIPS for PH with the only purpose of improving clinical practice.

BACKGROUND/AIMS: Gastric varices (GVs) are a major cause of upper gastrointestinal bleeding in patients with liver cirrhosis. The current treatments of choice are balloon-occluded retrograde transvenous obliteration (BRTO) and the placement of a transjugular intrahepatic portosystemic shunt (TIPS). We aimed to compare the efficacy and outcomes of these two methods for the management of GV bleeding. METHODS: This retrospective study included consecutive patients who received BRTO (n=157) or TIPS (n=19) to control GV bleeding from January 2005 to December 2014 at a single tertiary hospital in Korea. The overall survival (OS), immediate bleeding control rate, rebleeding rate and complication rate were compared between patients in the BRTO and TIPS groups. RESULTS: Patients in the BRTO group showed higher immediate bleeding control rates (p=0.059, odds ratio [OR]=4.72) and lower cumulative rebleeding rates (log-rank p=0.060) than those in the TIPS group, although the difference failed to reach statistical significance. There were no significant differences in the rates of complications, including pleural effusion, aggravation of esophageal varices, portal hypertensive gastropathy, and portosystemic encephalopathy, although the rate of the progression of ascites was significantly higher in the BRTO group (p=0.02, OR=7.93). After adjusting for several confounding factors using a multivariate Cox analysis, the BRTO group had a significantly longer OS (adjusted hazard ratio [aHR]=0.44, p=0.01) and a longer rebleeding-free survival (aHR=0.34, p=0.001) than the TIPS group. CONCLUSIONS: BRTO provides better bleeding control, rebleeding-free survival, and OS than TIPS for patients with GV bleeding.

BACKGROUND: To evaluate the safety and efficacy of transjugular intrahepatic portosystemic shunt (TIPS) creation for the management of portal hypertension in patients with hepatocellular carcinoma (HCC). METHODS: A literature search of the MEDLINE/PubMed and Embase databases was conducted. All articles reporting the outcomes of TIPS creation for variceal bleeding and refractory ascites and hepatic hydrothorax in patients with HCC were included. Exclusion criteria were non-English language, sample size < 5, data not extractable, and data reported in another article. RESULTS: A total of 280 patients (mean age, 48–58; male gender, 66%) from five articles were included. TIPS creation was performed for variceal bleeding in 79% and refractory ascites and/or hepatic hydrothorax in 26% of patients. Technical and clinical success was achieved in 99% and 64% of patients, respectively. Clinical failure occurred in 36% of patients due to rebleeding or recurrent bleeding (n = 77) or no resolution or improvement of refractory ascites and hepatic hydrothorax (n = 24). One percent of patient had major complications, including accelerated liver failure (n = 1) and multi-organ failure resulting from hemorrhagic shock (n = 1), all of which resulted in early (i.e., within 30 days) death. Hepatic encephalopathy occurred in 40% of patients after TIPS creation. Lung metastasis was found 1% of patient 5 months (n = 1) and 72 months (n = 1) after TIPS creation. CONCLUSION: TIPS creation seems to be safe and effective for the management of portal hypertension in patients with HCC.

Transjugular intrahepatic portosystemic shunts (TIPS) are widely used in the management of bleeding gastric varices (GV). More recently, several studies have demonstrated balloon-occluded retrograde transvenous obliteration (BRTO) as an effective treatment method for bleeding isolated GV, especially in patients with contraindications for a TIPS placement. Both TIPS and BRTO can effectively treat bleeding GV with low rebleeding rates. Careful patient selection for TIPS and BRTO procedures is required to best treat the patient's individual clinical situation.

Summary of Event: A transjugular intrahepatic portosystemic shunt (TIPS) stent (Viatorr) was misplaced into main portal vein and superior mesenteric vein. This misplaced covered stent was then successfully retrieved using the rigid endobronchial forceps. Teaching Point: Before release the covered portion of the TIPS stent (Viatorr), it is necessary to confirm the position of uncovered portion in portal vein and covered portion in parenchymal tract. The endobronchial forceps technique is a safe and efficient method for retrieving a misplaced TIPS stent.

BACKGROUNDBalanced adjustment of the portal vein shunt volume during a transjugular intrahepatic portosystemic shunt (TIPS) is critical for maintaining liver perfusion and decreasing the incidence of liver insufficiency. A stent-graft is proved to be superior to a bare metal stent (BMS) for the construction of a TIPS. However, the clinical results of the combination application of stents and stent-grafts have not been determined. This study aimed to compare the technique of using a combination of stents and stent-grafts with using a single stent-graft to construct a TIPS.

METHODSFrom April 2011 to November 2014, a total of fifty patients were randomly assigned to a stents-combination group (Group I, n = 28) or a stent-graft group (Group II, n = 22). Primary patency rates were calculated. Clinical data, including the technical success rate, bleeding control results, incidence of encephalopathy, liver function preservation, and survival rate, were assessed.

RESULTSTechnically, the success rate was 100% for both groups. The primary patency rates at 1, 2, and 3 years for Group I were 96%, 84%, and 77%, respectively; for Group II, they were 90%, 90%, and 78%, respectively. The survival rates at 1, 2, and 3 years for Group I were 79%, 74%, and 68%, respectively; for Group II, they were 82%, 82%, and 74%, respectively. The incidence of hepatic encephalopathy was 14.3% for Group I and 13.6% for Group II. The Child-Pugh score in Group I was stable at the end of the follow-up but had significantly increased in Group II (t = -2.474, P = 0.022).

CONCLUSIONSThe construction of a TIPS with either the single stent-graft or BMS/stent-graft combination is effective for controlling variceal bleeding. The BMS/stent-graft combination technique is superior to the stent-graft technique in terms of hepatic function preservation indicated by the Child-Pugh score. However, considering the clinical results of the TIPS, the two techniques are comparable in their primary shunt patency, incidence of encephalopathy and patient survival during the long-term follow-up.
