Based on the result of the contrast examination, decide whether to conduct another examination. * Keep a diary of their symptoms and therapeutic process in 30 days.

High Dose Albumin in Refractory Ascites

Advanced cirrhosis with complications is a serious problem imposing a heavy financial burden on health care system. Moreover, ascites is associated with increase in mortality rates among cirrhotic patients. Ascites pathogenesis is multifactorial including: portal hypertension; splanchnic and peripheral arterial vasodilation; and neurohumoral activation. Current management strategies include dietary sodium restriction and diuretic therapy, however, this strategy put patients at the risk of intravascular volume depletion, renal impairment, hepatic encephalopathy and hyponatremia. Moreover, around 10% of patients do not respond to this strategy (termed: diuretics resistant) with 50% of them die within 6 months. This sub-group is managed by frequent large volume paracentesis along with intravenous albumin administration and are usually considered for liver transplantation (LT) and TIPS. Nonetheless, Frequent paracentesis increases the risk of infection, bleeding, bowel perforation, paracentesis-induced circulatory dysfunction (PICD) and renal dysfunction in this sub-group of patients. The beneficial effect of human albumin might result from blood volume expansion tapering activated vasoconstrictor and sodium-retaining systems improving renal perfusion, hence regular infusion of albumin may be beneficial to prevent development of ascites and to improve survival. The positive effects of albumin are supported by previous studies; Romanelli et al, showed a significant increase in survival rate among cirrhotic patients with ascites when compared to those who did not receive albumin. Moreover, a randomized multicenter open label trial published in lancet last year, demonstrated that long term albumin administration improved 18-month survival, decreased the use of paracentesis and decrease in the incidence of cirrhosis related complications among cirrhotic patients with ascites. As of today, there's a limited use of regular high dose albumin in cirrhotic patients with ascites in US, despite being used elsewhere in the world as previously stated. The investigators wish to study long-term efficacy of human albumin administration in patients with decompensated cirrhosis to assess safety and efficacy, and prevention of complications of cirrhosis.

VICIS - Vienna Cirrhosis Study

Patients with advanced chronic liver diseases treated at the Vienna General Hospital of the Medical University of Vienna will be offered to participate in this prospective observational trial - including an optional participation in a biobank. Clinical parameters and laboratory parameters will be recorded for all patients and patients will undergo a regular follow-up schedule with clinical visits at the Vienna General Hospital. This study is linked to a biobank with serum/plasma, ascitic fluid, urine, GI tract mucosal biopsies, liver biopsies and stool collected from the study participants.

Free Fluid Detection With Telementored eFAST

This feasibility study will evaluate the accuracy of telementored eFAST (Extended Focused Assessment with Sonography in Trauma) in detecting abdominal free fluid in patients who have recently undergone liver surgery. The primary goal is to determine how well the remote-guided ultrasound can identify fluid accumulation compared to conventional ultrasound performed by a radiologist. Participants in this study will be examined with ultrasound, supported in real-time by a remote expert, to assess its accuracy and other relevant performance metrics.

Kinesio-Taping vs. Usual Care for Malignant Bowel Obstruction With Ascites

The goal of this clinical trial is to find out whether abdominal Kinesio-taping is a feasible and effective way to relieve symptoms in patients with malignant bowel obstruction and ascites who still have severe symptoms after surgery, medication, or nasogastric tube treatment. The main questions it aims to answer are: * Can abdominal Kinesio-taping reduce the severity of symptoms, such as abdominal pain, bloating, and nausea, in these patients? * Is abdominal Kinesio-taping a safe and practical treatment option for this patient group? Participants in this study are adults with cancer who have been diagnosed with malignant bowel obstruction and ascites, and whose symptoms have not improved after standard medical treatments. People who are allergic to tape, have abdominal wounds, are pregnant, or are unable to provide consent will not be included. Participants will be randomly assigned to one of two groups: * The Kinesio-taping group will receive standard care for malignant bowel obstruction plus abdominal Kinesio-taping, applied by trained professionals using a standardized procedure. * The control group will receive standard care only. The main outcomes measured will be changes in symptom severity using the Edmonton Symptom Assessment System (ESAS) modified for ascites, as well as abdominal girth and pain medication use. Symptoms and side effects will be closely monitored to ensure safety. The information from this study may help determine whether Kinesio-taping can be an additional, safe, and effective option for managing symptoms in patients with advanced cancer who have malignant bowel obstruction and ascites.

Application of Bacterial DNA Quantitative Detection in Diagnosis of SBP in Cirrhosis: A Multi Center Diagnostic Experiment

Background and Significance: Spontaneous bacterial peritonitis (SBP) is a common and life-threatening complication in patients with liver cirrhosis, characterized by high incidence and mortality. The current diagnostic standard relies on ascitic fluid polymorphonuclear leukocyte (PMN) count ≥250 cells/μL. However, this threshold is associated with high rates of missed diagnoses, poor correlation with clinical symptoms, and delays in pathogen identification due to the low sensitivity and prolonged time of traditional ascitic fluid culture. With the development of molecular diagnostics, bacterial DNA (bactDNA) detection-especially through droplet digital PCR (ddPCR)-has emerged as a promising technique due to its high sensitivity, absolute quantification capability, and robustness. This study aims to evaluate the diagnostic value and accuracy of ddPCR-based quantification of bacterial DNA in ascitic fluid for SBP, providing a novel and objective diagnostic tool to improve early and accurate detection and to inform targeted antimicrobial therapy. Objectives: To assess the diagnostic accuracy (sensitivity, specificity, predictive values) of ddPCR-based quantification of total bacterial DNA in ascitic fluid for SBP. To evaluate the diagnostic performance of the ratio of Gram-positive to Gram-negative bacterial DNA (G+/G-) in predicting SBP. To explore the potential of ddPCR-based bacterial DNA quantification as a complementary or alternative method to conventional PMN-based diagnostic criteria. Study Design and Methods: This is a prospective diagnostic study involving 700 patients with liver cirrhosis and ascites. Ascitic fluid samples will be analyzed using ddPCR to quantify bacterial DNA levels. These results will be compared with traditional diagnostic criteria, including PMN counts and expert panel assessments based on clinical symptoms and laboratory findings. Statistical analyses will include correlation analysis, ROC curve analysis, and consistency testing. Expected Outcomes: The study aims to establish the clinical efficacy of ddPCR-based quantification of bacterial DNA in ascitic fluid as a novel diagnostic marker for SBP. This method is expected to be particularly useful in atypical cases where PMN counts are \<250/μL and may help guide preliminary antibiotic selection based on the proportion of Gram-positive and Gram-negative bacteria, thereby reducing empirical treatment failures and antibiotic resistance.

Comparing Ascites Relief In Two Standard Treatments: Large Volume Paracentesis Vs. Early Tips Using Viatorr Controlled Expansion Stents

For this study, the investigators will be collecting data based on patients' random selection to two different approved standard of care treatments for ascites: Subjects will get randomized into either Group A: Large Volume Paracentesis (LVP) with albumin infusion, or Group B: an early transjugular intrahepatic portosystemic shunt (TIPS) procedure.

Medical-economic Evaluation of the Care of Refractory Ascites by Implantation of Alfapump® Device in Cirrhotic Patients

The hypothesis is that the Alfapump® strategy would be more effective in terms of QALYs generated , and that the cost of Alfapump® device and its implantation will be totally or partially offset by the reduction in the number of evacuating parentheses performed and the reduction in the number of complications in patients with refractory ascites awaiting liver transplantation or not. On the other hand, given the difference in the clinical profiles of these two populations (whether or not they are awaiting transplantation), these two populations will be study separately Evaluation of the medical-economic impact at 1 year of the two therapeutic strategies: implantation of Alfapump® versus repeated evacuating paracentesis in cirrhotic patients with refractory ascites without scheduled liver transplantation.

Drug Sensitivity of Hydrothorax and Ascite Organoids from Breast Cancer

Malignant hydrothorax and ascitic fluid in advanced breast cancer often arise from metastasis to the lungs, pleura, or liver. Patients with this condition experience rapid disease progression and multidrug resistance, facing limited treatment options. Clinical guidelines offer various therapies based on molecular subtypes; however, their effectiveness can be hindered by prior treatments, patient health, and tumor evolution. Current evaluations of treatment efficacy typically take two cycles, delaying the recognition of ineffective therapies and resulting in unnecessary side effects and costs. Organoid models present a promising solution, accurately replicating tumor structure and cellular diversity compared to traditional methods. These patient-derived models facilitate improved drug sensitivity testing, leading to more personalized treatment plans. In this study, 90 patients diagnosed with metastatic breast cancer accompanied by hydrothorax and ascitic fluid will be recruited. Patient-derived organoids will be used to assess the sensitivity of chemotherapy regimens, including Doxorubicin, Carboplatin, Cyclophosphamide, and Paclitaxel, along with targeted therapies such as Herceptin and Pertuzumab.

High Definition Profiling of Ovarian Cancer Ascites

This project entails the collection of a prospective cohort of ascites (AS) samples from High Grade Serous Ovarian Cancer (HGSOC) patients. High Grade Serous Ovarian Cancer (HGSOC) is a major cause of cancer-related mortality, due to the late-stage diagnosis and failure of surgery and chemotherapy (CHT) to eradicate the disease with no significant improvement in overall survival. The primary objective of the project is to generate a comprehensive map of ascites cell components, detailing both their intrinsic features and the landscape of cellular interactions mediated by soluble factors in ascitic fluid.
