Active clinical trials for "Ascites"

Ascites is the accumulation of fluid inside the abdomen. This can happen when the liver fails due to a substantial amount of scarring (cirrhosis). Patients (pts) must have this fluid drained and as cirrhosis progresses, patients will require drainage of ascites repeatedly on a regular basis, leading to frequent hospitals visits and increased complications. The current drainage device is slow and doesn't always drain completely so pts have to return repeatedly to keep symptoms under control. A new device (called Melody) has been developed and specifically designed for the purpose of draining ascites fluid, which the Investigators expect to drain faster and completely. This study will compare the volume of ascites drained using the new 'Melody' catheter device with that used in standard NHS practice. If the melody catheter device is confirmed as superior to the current device this would improve patient experience (less frequent visits to hospital and increased length of time between visits). With fewer procedures performed per patient, the pressure on the NHS would be greatly reduced in terms of time and costs.

Paracentesis is a bedside procedure in which a needle is inserted into a patient's peritoneum in order to obtain ascitic fluid. This is a safe bedside procedure with very low risks of complications that is usually performed using physical exam maneuvers to determine the site of needle insertion. Point of care ultrasound (POCUS) technology has improved the safety of central venous catheter insertion and thoracentesis, yet the data on safety in paracentesis is equivocal. In a practical study, we aim to determine if POCUS will change the needle insertion site over the traditional anatomic landmarking method. Operators will landmark for paracentesis using conventional physical exam and then utilize POCUS to determine if there is a more optimal site. The primary endpoint will be whether POCUS yielded a change in the needle insertion site, as defined by a location greater than 5cm from the anatomic site, at least 20% of the time. The results will further our understanding of POCUS in improving procedural safety, thereby adding to the currently limited literature on this topic. Furthermore, this study will inform residency training programs about the utility in POCUS training for paracentesis and may advocate for the availability of POCUS devices to physicians performing this procedure.

The role of teleradiology has far reaching implications for the health of remote and underserved populations. The ability to coordinate radiographic evaluation and diagnosis from a distance has the potential to raise the standard of patient care throughout the world. Perhaps the safest and most cost effective mode of teleradiology today is telesonography. The current project attempts to determine the extent that telesonography improves the standard of care within a rural government-run primary clinic within the Dominican Republic. The work reported herein is intended to compare the use of telesonography to the current standard of sonographic examination (referral to government hospital 60km from target clinic). The study was conducted by randomly assigning 100 patients with clinical indications for sonographic examination into experimental and control groups. Following a 60-day implementation period, the following research questions will be addressed: 1) To what extent does the use of asynchronous telesonography increase the percentage of definitive diagnoses based on the total number of scans (definitive diagnoses / total number of scans)? 2) To what extent does the use of asynchronous telesonography increase the continuity of care for patients? 3) To what extent does the elapsed time between scanning and final radiological interpretation decrease with the use of asynchronous telesonography? This study will also look at the history of telemedicine / telesonography and its dissemination into the mainstream practice of medicine, explore training protocols that may be used to assist others to establish new telesonography programs in a developing nations, and discuss both advances and persistent barriers to the implementation of telesonography programs. Hypothesis: The use of a store-and-forward telesonography system in this setting will increase the speed and number of final diagnoses per scan received by the target clinic and will increase the continuity of care by increasing the number and speed of follow-up appointments to the target clinic.

Refractory ascites (fluid build up in the abdomen that can not bet managed by medications) occurs in at least 10% of patients with end stage liver disease (cirrhosis). Two major options for management include large volume paracentesis (LVP)-drainage with a needle through the abdominal wall) and placement of a transjugular intrahepatic portosystemic shunt (TIPS)-re-directs blood flow across the cirrhotic liver), Not all patients are candidates for TIPS or transplant, are left with LVP as the only long-term treatment option. Patients listed for transplant require LVP while they wait for transplant. LVP can cause pain, bleeding, leakage from the drain site and frequent hospital visits which result in health care cost as well as patient and caregiver fatigue. In between the drains, living with ascites can negatively affect quality of life because of discomfort and limitations. Patients with ascites are more malnourished than those without. Specialized drains tunnelled under the skin, are used in patents with ascites due to cancer (malignant). There are not many studies evaluating these drains in patients with cirrhosis, One of the reasons for the lack of studies is the potential for infection. As opposed to malignant ascites, cirrhotic ascites generally has a low protein content, a risk factor for development of spontaneous bacterial peritonitis (SBP). From available studies, infection rates in cirrhotic patients with tunnelled drains who are not on antibiotics are estimated at 10% (4/40). Infection rates on antibiotic prophylaxis would be expected to be lower. This pilot study includes the evaluation of indwelling tunnelled PleurX catheters as an alternative option. The hypothesis is that with careful monitoring of kidney function and prevention of infection with antibiotics, PleurX catheters will be safe, cost-effective and improve quality of life and nutritional status compared to the standard of care.

The purpose of this study is to investigate the effect of terlipressin on myocardial perfusion and renal function. Hypothesis: Significant improvement of renal function reflected by: glomerular filtration rate (GFR), renal blood flow (RBF), excretion of salt and metabolites in the urine and related hormones and peptides in the blood. No effect on the systolic function of the heart.

Portal vein hypertension is associated with post-hepatectomy liver failure in patients with liver cirrhosis. Our previous study found that bolus injection of 1 mg terlipressin immediately after hepatectomy decreased portal vein pressure, and post-operative continuous use of terlipressin decreased the amount of abdominal drain. In this multicenter randomized controlled study, we aim to evaluate the effects of terlipressin in the patients who underwent liver resection complicated by portal vein hypertension.

The development of ascites is a landmark event in the natural history of cirrhosis and signifies a grim prognosis. Portal hypertension and splanchnic arterial vasodilatation are the major contributors in the development of ascites. Vasodilatation with the consequential decrease in effective circulating volume leads to the activation of sympathetic nervous system and renin angiotensin aldosterone system (RAAS), leading to antinatriuretic effects and retention of sodium and water. This results in the formation of ascites. Management of ascites primarily consists of salt restrictrion and diuretics. Liver transplant is the ultimate panacea. Dapaglifozin, a Sodium glucose linked transporter-2(SGLT-2) inhibitor, is a part of the routine armamentarium for treatment of patients with Diabetes Mellitus type-2. Its safety is well established in non-diabetic patients too where it has been shown to improve cardiovascular outcomes. The risk of hypoglycemia is negligible as its action is independent of insulin. By virtue of its natriuretic effect, it has been shown to reduce hospitalisations in patients with heart failure irrespective of the presence of diabetes. We hypothesise that a similar natriuretic effect may help in suppressing the renin-angiotensin axis with improved mobilization of ascites in patients with cirrhosis. Pharmacokinetic data on the use of Dapaglifozin suggest that there is no need for dose modification in cirrhosis. The AUC and Cmax for Dapaglifozin in Child Pugh C cirrhosis is 67% and 40%, respectively. In a recent small case series, SGLT-2 inhibitors including dapaglifozin led to improvement in fluid retention and serum sodium, without acute kidney injury or encephalopathy, in patients with cirrhosis. However, SGLT-2 inhibitors have not been evaluated in randomized controlled trials. In this pilot study, we plan to evaluate the efficacy and safety of dapaglifozin in cirrhotics patients with recurrent ascites.

The purpose of the present study is to investigate whether or not to perform elective surgical repair of umbilical hernias in patients with liver cirrhosis and ascites. There are no other randomized controlled trials in this area. The optimal management in patients with umbilical hernias and liver cirrhosis with ascites is not clear yet. The general surgical opinion is that umbilical hernias in patients with ascites should not be corrected because of the supposedly high operative risks and high recurrence rates. Conservative treatment, however, can have severe complications resulting in emergency repair. Such operations carry a higher risk of complications than elective operations, particularly in this group of patients. Prospective and retrospective series showed us that elective hernia repair in this specific patient group is safe without major complications or high recurrence rates. The aim of this study is to asses the optimal timing of correction of umbilical hernia in patients with liver cirrhosis and ascites.

The purpose of this study is to determine the effectiveness of using Bevacizumab in the prevention of recurrent malignant ascites. Ascites is a debilitating and unpleasant complication of several types of cancer. Animal and laboratory studies have shown that tumor cell production and/or increases in the amount of Vascular Endothelial Growth Factor (VEGF) is a major cause of the formation of malignant ascites. Therefore, giving patients with malignant ascites a drug that targets and neutralizes VEGF should prevent the recurrence of malignant ascites following paracentesis (a procedure to remove fluid from the abdominal cavity).
