Project description:RationaleTransjugular intrahepatic portosystemic shunt (TIPS) is mainly used to treat acute and chronic esophageal, gastric, and intestinal variceal bleeding and refractory ascites caused by portal hypertension. The most common complication of TIPS is the development of hepatic encephalopathy (HE). Fecal microbiota transplantation (FMT) is an emerging method for treating diseases by altering the intestinal flora. We present 2 cases of FMT that ameliorated liver function and HE after TIPS.Patient concernsIn this report, 2 patients with liver cirrhosis secondary to hepatitis B had recurrent Grade 2-3 HE after TIPS.DiagnosisTwo patients were diagnosed as having HE.InterventionsThe 2 patients separately received 3 times of FMT.OutcomesThe liver function of both patients improved, the clinical symptoms were relieved, and the number of HE attacks decreased significantly after FMT.LessonsFMT may be another effective way to treat HE, and is worthy of further research.

Project description:Background/purposeOvert hepatic encephalopathy (HE) risk should be preoperatively predicted to identify patients suitable for curative transjugular intrahepatic portosystemic shunt (TIPS) instead of palliative treatments.MethodsA total of 185 patients who underwent TIPS procedure were randomised (130 in the training dataset and 55 in the validation dataset). Clinical factors and imaging characteristics were assessed. Three different models were established by logistic regression analyses based on clinical factors (ModelC), imaging characteristics (ModelI), and a combination of both (ModelCI). Their discrimination, calibration, and decision curves were compared, to identify the best model. Subgroup analysis was performed for the best model.ResultsModelCI, which contained two clinical factors and two imaging characteristics, was identified as the best model. The areas under the curve of ModelC, ModelI, and ModelCI were 0.870, 0.963, and 0.978 for the training dataset and 0.831, 0.971, and 0.969 for the validation dataset. The combined model outperformed the clinical and imaging models in terms of calibration and decision curves. The performance of ModelCI was not influenced by total bilirubin, Child-Pugh stages, model of end-stage liver disease score, or ammonia. The subgroup with a risk score ≥ 0.88 exhibited a higher proportion of overt HE (training dataset: 13.3% vs. 97.4%, p < 0.001; validation dataset: 0.0% vs. 87.5%, p < 0.001).ConclusionOur combination model can successfully predict the risk of overt HE post-TIPS. For the low-risk subgroup, TIPS can be performed safely; however, for the high-risk subgroup, it should be considered more carefully.

Project description:ObjectiveTo develop and evaluate a machine learning-based CT radiomics model for the prediction of hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic shunt (TIPS).MethodsA total of 106 patients who underwent TIPS placement were consecutively enrolled in this retrospective study. Regions of interest (ROIs) were drawn on unenhanced, arterial phase, and portal venous phase CT images, and radiomics features were extracted, respectively. A radiomics model was established to predict the occurrence of HE after TIPS by using random forest algorithm and 10-fold cross-validation. Receiver operating characteristic (ROC) curves were performed to validate the capability of the radiomics model and clinical model on the training, test and original data sets, respectively.ResultsThe radiomics model showed favorable discriminatory ability in the training cohort with an area under the curve (AUC) of 0.899 (95% CI, 0.848 to 0.951), while in the test cohort, it was confirmed with an AUC of 0.887 (95% CI, 0.760 to 1.00). After applying this model to original data set, it had an AUC of 0.955 (95% CI, 0.896 to 1.00). A clinical model was also built with an AUC of 0.649 (95% CI, 0.530 to 0.767) in the original data set, and a Delong test demonstrated its relative lower efficiency when compared with the radiomics model (p < 0.05).ConclusionMachine learning-based CT radiomics model performed better than traditional clinical parameter-based models in the prediction of post-TIPS HE.Advances in knowledgeRadiomics model for the prediction of post-TIPS HE was built based on feature extraction from routine acquired pre-operative CT images and feature selection by random forest algorithm, which showed satisfied performance and proved the advantages of machine learning in this field.

Project description:BackgroundPatients with cirrhosis often develop portal hypertension-associated splenomegaly and hypersplenism, potentially causing severe cytopenia.AimsSystematic assessment on the impact of transjugular intrahepatic portosystemic shunt (TIPS) implantation on platelet count (PLT), hemoglobin (Hb), and white blood cell count (WBC).MethodsPatients with cirrhosis undergoing covered TIPS implantation were retrospectively included. Patients with malignancies or hematologic disorders were excluded. Hematology lab work was recorded at baseline (pre-TIPS) and at regular intervals after TIPS.ResultsOne hundred ninety-two patients (male: 72.4%, age: 56 ± 10 years; MELD: 12.1 ± 3.6) underwent TIPS implantation. Higher-grade (≥ G2) thrombocytopenia (PLT < 100 G/L) was present in 54 (28.7%), ≥ G2 anemia (Hb < 10 g/dL) in 57 (29.7%), and ≥ G2 leukopenia (WBC < 2 G/L) in 3 (1.6%) patients pre-TIPS, respectively. Resolution of ≥ G2 thrombocytopenia, anemia, and leukopenia occurred in 24/55 (43.6%), 23/57 (40.4%), and 2/3 (66.7%), respectively. Similar results were also observed in the subgroup of patients without 'bleeding' TIPS-indication, with improvements of G ≥ 2 thrombocytopenia and of G ≥ 2 anemia in 19.8% and 10.2% of patients after TIPS, respectively.ConclusionsThrombocytopenia, anemia, and leukopenia frequently improved after TIPS. Therefore, moderate- to higher-grade thrombocytopenia should not be regarded as a contraindication against TIPS, but rather be considered in case of severe thrombocytopenia-particularly prior to surgery or interventions.

Project description:BackgroundThis study aimed to evaluate whether a large paraumbilical vein (L-PUV) was independently associated with the occurrence of overt hepatic encephalopathy (OHE) after the implantation of a transjugular intrahepatic portosystemic shunt (TIPS).MethodsThis bi-center retrospective study included patients with cirrhotic variceal bleeding treated with a TIPS between December 2015 and June 2021. An L-PUV was defined in line with the following criteria: cross-sectional areas > 83 square millimeters, diameter ≥ 8 mm, or greater than half of the diameter of the main portal vein. The primary outcome was the 2-year OHE rate, and secondary outcomes included the 2-year mortality, all-cause rebleeding rate, and shunt dysfunction rate.ResultsAfter 1:2 propensity score matching, a total of 27 patients with an L-PUV and 54 patients without any SPSS (control group) were included. Patients with an L-PUV had significantly higher 2-year OHE rates compared with the control group (51.9% vs. 25.9%, HR = 2.301, 95%CI 1.094-4.839, p = 0.028) and similar rates of 2-year mortality (14.8% vs. 11.1%, HR = 1.497, 95%CI 0.422-5.314, p = 0.532), as well as variceal rebleeding (11.1% vs. 13.0%, HR = 0.860, 95%CI 0.222-3.327, p = 0.827). Liver function parameters were similar in both groups during the follow-up, with a tendency toward higher shunt patency in the L-PUV group (p = 0.067). Multivariate analysis indicated that having an L-PUV (HR = 2.127, 95%CI 1.050-4.682, p = 0.037) was the only independent risk factor for the incidence of 2-year OHE.ConclusionsHaving an L-PUV was associated with an increased risk of OHE after a TIPS. Prophylaxis management should be considered during clinical management.

Project description:Background and aimHepatic encephalopathy (HE) is a serious complication of decompensated liver cirrhosis, affecting the prognosis of patients underwent transjugular intrahepatic portosystemic shunts (TIPS). We aim to create a nomogram to predict hepatic encephalopathy- free survivals (HEFS) after TIPS in cirrhotic patients and select appropriate candidates for TIPS.MethodsCirrhotic patients underwent TIPS from 2015 to 2018 in our department were included. Multivariable Cox regression was conducted to estimate the predictors of overt HE (OHE) after TIPS within one year. A nomogram based on the Cox proportional hazard model using data from a retrospective training cohort (70% of the patients) was developed. Then the prediction model was validated in the remaining 30% patients by Harrell's C-indexes, ROC curves and calibration plots.ResultsOf 373 patients, 117 developed postoperative OHE (31.4%). The training and validation groups comprised 83 (31.4%) and 34 (31.2%) patients, respectively. The cumulative survival rates of patients with HE at 1, 2 and 3 years were 90%, 83% and 76%, respectively. The nomogram included the following variables: age, Child-Turcotte-Pugh class (CTP class), diabetes mellitus (DM), serum creatinine and serum sodium (C-index = 0.772). The C-index for HEFS prediction was 0.773 for the validation cohort. The ROC for predicting HEFS was 0.809 and 0.783, respectively.ConclusionsWe created a nomogram of predicting postoperative HEFS in cirrhotic patients received TIPS. This nomogram could be an important tool of HE risk prediction before TIPS to guide the therapeutic strategy in cirrhotic patients.

Project description:ObjectivesHepatic hydrothorax (HH) is a predictor of poor survival in cirrhosis patients. However, whether HH increases the mortality risk of cirrhosis patients treated with transjugular intrahepatic portosystemic shunt (TIPS) is unknown. Our objective was to evaluate the influence of HH on the survival of cirrhosis patients after TIPS.MethodsCirrhosis patients with portal hypertension complications were selected from a prospective database of consecutive patients treated with TIPS in Xijing Hospital from January 2015 to June 2021. Cirrhosis patients with HH were treated as the experimental group. A control group of cirrhosis patients without HH was created using propensity score matching. Survival after TIPS and the related risk factors were analysed.ResultsThere were 1292 cirrhosis patients with portal hypertension complications treated with TIPS, among whom 255 patients had HH. Compared with patients without HH, patients with HH had worse liver function (MELD, 12 vs. 10, p < 0.001), but no difference in survival after TIPS was observed. After propensity score matching, 243 patients with HH and 243 patients without HH were enrolled. There was no difference in cumulative survival between patients with and without HH. Cox regression analysis showed that HH was not associated with survival after TIPS, and main portal vein thrombosis (> 50%) was a prognostic factor of long-term survival after TIPS in cirrhosis patients (hazard ratio, 1.386; 95% CI, 1.030-1.865, p = 0.031).ConclusionHepatic hydrothorax does not increase the risk of death after TIPS in cirrhosis patients.Key points• Hepatic hydrothorax is a decompensated event of cirrhosis and increases the risk of death. • Hepatic hydrothorax is associated with worse liver function. • Hepatic hydrothorax does not increase the mortality of cirrhosis treated with TIPS.

Project description:BackgroundSarcopenia and myosteatosis have been associated to a poor prognosis of cirrhosis and to a higher incidence of hepatic encephalopathy (HE). The prognostic implications of visceral and subcutaneous adiposity are less known.AimTo evaluate the modifications of visceral and subcutaneous adipose tissue after TIPS and to investigate their relationships with the modification of muscle mass and with the incidence of post-TIPS HE.Patients and methods35 cirrhotic patients submitted to TIPS were retrospectively studied. The modification of skeletal muscle index (SMI), muscle attenuation (myosteatosis), subcutaneous adipose tissue index (SATI), visceral adipose tissue index (VATI), assessed by CT-scan and plasma ammonia were evaluated before and after a mean follow-up of 19 ± 15 months after TIPS. The number of episodes of overt HE was also recorded.ResultsDuring the follow-up, the mean SMI and muscle attenuation increased significantly; SATI significantly increased while VATI significantly decreased, although not uniformly in all patients. By comparing the patients with or without improvement in their nutritional status after TIPS, MELD remained stable while the number of episodes of overt HE was significantly lower in the patients with improved SMI and in the patients with improved SATI. Finally, inverse correlation was observed between the variation of ammonia and SATI (r = -.40; P < .05).ConclusionIn addition to muscle mass, adipose tissue is modified after TIPS. The improvement of subcutaneous adipose tissue as well as of sarcopenia and myosteatosis is associated to the amelioration of cognitive impairment independently of liver function. The correlation between adipose tissue and ammonia modification may suggest an active role of the adipose tissue in the inter-organ ammonia trafficking.

Project description:The present study aimed to investigate (1) the association between left ventricular diastolic dysfunction (LVDD), graded according to the algorithm proposed by the Cirrhotic Cardiomyopathy Consortium, and long-term survival in patients with cirrhosis undergoing transjugular intrahepatic portosystemic shunt (TIPS) and (2) the additive prognostic value of left atrial (LA) function, as assessed by LA reservoir strain, using two-dimensional speckle-tracking echocardiography (2D-STE). A total of 129 TIPS candidates (mean ± SD, 61 ± 12 years; 61% men) underwent a comprehensive preprocedural echocardiography. LA dysfunction was defined by LA reservoir strain ≤35%, based on a previously suggested cut-off value. The outcome was all-cause mortality after TIPS. In the current cohort, 65 (50%) patients had normal diastolic function, 26 (20%) patients had grade 1 LVDD, 21 (16%) patients had grade 2 LVDD, and 17 (13%) patients had indeterminate diastolic function. Additionally, LA dysfunction (based on LA reservoir strain ≤35%) was noted in 67 (52%) patients. After a median follow-up of 36 months (range, 12-80), 65 (50%) patients died. All-cause mortality rates increased along worse grades of LVDD (log-rank p = 0.007) and with LA dysfunction (log-rank p = 0.001). On multivariable Cox regression analysis, Model for End-Stage Liver Disease score (hazard ratio [HR],1.06; p = 0.003), hemoglobin (HR, 0.74; p = 0.022), and LA strain, expressed as a continuous variable (HR, 0.96; p = 0.005) were independently associated with all-cause mortality. Notably, the addition of LA strain to the model provided incremental prognostic value over the established prognostic variables (delta χ2 = 8.27, p = 0.004). Conclusion: LA dysfunction assessed with 2D-STE is independently associated with all-cause mortality in patients with cirrhosis treated by TIPS.
