Filter by:This pilot study seeks to demonstrate the efficacy of an intravenous lipid preparation high in omega-3 fatty acids (Omegaven) in the treatment of cholestasis in parenteral nutrition dependent patients with short gut syndrome.
Patients who are not able to eat normally for a longer time require parenteral nutrition, i.e. they receive liquids and nutrients directly into their veins. This can have many long-term side effects, including liver problems. This study will examine whether a specific lipid emulsion containing fish oil can improve liver disease in patients on parenteral nutrition. The investigators will compare changes in bilirubin and liver enzymes after 3 months in 10 patients receiving standard lipid emulsion to 10 patients receiving standard lipids + a fish-oil containing emulsion. The investigators will also assess liver histology, the kind of fat, oxidative stress and gene expression in the liver at the beginning and after 6 months of fish-oil. The investigators also want to compare the baseline values from all 20 patients to 20 healthy controls. This will help to explain how fish oil may improve liver disease in patients on parenteral nutrition.
Currently, very few centers offer Photodynamic therapy for unresectable Cholangiocarcinoma in the United States. Several European studies have reported the efficacy and safety of Photodynamic Therapy (PDT) for Cholangiocarcinoma, however, only a few studies have reported the same in the United States. The establishment of a registry to capture all PDT cases within and outside US can help the investigators evaluate a larger and non-ambiguous sample population. This would help the investigators evaluate the technical success rates, clinical success rates, feasibility and safety of PDT for unresectable cholangiocarcinoma. With more endoscopists considering PDT as a therapeutic option along with adjuvant treatment for cholangiocarcinoma, there is a need to further evaluate the efficacy and safety of such combined procedures as well. The ultimate objective is to assess if PDT with or without additional or adjuvant treatment options prolongs survival duration and improves quality of life in patients with unresectable cholangiocarcinoma. This multicenter registry has been initiated: - To document the impact of PDT on the clinical management of unresectable cholangiocarcinoma. - To assess the clinical and technical success rates of PDT for unresectable cholangiocarcinoma.
The purpose of this registry is to record information and evaluate the impact of Endoscopic Ultrasound (EUS) Guided Endoscopic retrograde cholangiopancreatography (ERCP) on the management of pancreatico-biliary disorders. The registry will evaluate efficacy, safety and technical success of the Endoscopic Ultrasound (EUS)Guided Endoscopic retrograde cholangiopancreatography (ERCP) procedures. The safety and efficacy of various EUS-Guided ERCP procedures have been assessed in a series of studies. This multi-center registry has been initiated: - To document the impact of EUS-Guided ERCP procedures on the management of pancreatico-biliary disorders including malignancies. - To assess the clinical and technical success rates of EUS-Guided ERCPs for diagnostic or therapeutic procedures. Design is retrospective and prospective registry study. Procedures that will be captured include: 1. EUS-Coils placement 2. EUS Glue injection 3. EUS-Fiducial placement 4. EUS-Neurolysis 5. EUS-Stent placement 6. EUS-alcohol injection 7. EUS-fluid collection, abscess or cavity drainage 8. EUS guided ductal drainage 9. EUS-guided Ablation 10. EUS-guided anastomosis 11. EUS Guided ERCP for gallbladder, pancreatic duct or biliary duct drainage
The objective of this protocol is to establish a multicenter registry to evaluate the impact of radiofrequency ablation in the management of patients with pancreatico-biliary disorders including malignancies.
The investigators will try to predict the risk of esophageal varices (EVs) in long-term BA survivors using noninvasive computed tomography (CT) or magnetic resonance (MR) indices and the measurement of transverse diameters of paraesophageal and gastroesophageal veins.
Prolonged use of parenteral nutrition can lead to parenteral nutrition associated liver disease (PNALD). The purpose of this study is to determine the effect of treatment with a smaller amount lipid minimization) of our standard soybean oil based intravenous lipid emulsion (Intralipid) versus a fish-oil based lipid emulsion (Omegaven) in infants with severe cholestasis.
The overall median survival of nonresectable malignant hilar obstruction in most series has been less than 6 months. Most patients with malignant hilar obstruction present with advanced disease, making palliative endoscopic drainage the principal therapeutic option. However, the optimal endoscopic management strategy is contentious. Almost all of the published data comparing plastic and metallic stents relate to distal tumors (those of the pancreas, common bile duct and ampulla). Stent patency, complication rates, and cost-effectiveness have favored metallic stents when compared with plastic stents in patients with distal malignant obstruction expected to live at least 3 to 6 months. There are few comparative study as to whether self-expanding metallic or plastic stent, especially DLS (double layer plastic stent) are preferable in the technical success, stent patency, and cost-effectiveness for palliating malignant hilar obstruction. The study was designed to compare the the technical success, stent patency, and cost-effectiveness of self-expandable metal stent and DLS in patients with malignant hilar obstruction.
The purpose of this study is to investigate whether the inclusion of 1g of intravenous taurine as part of the nitrogen source of parenteral nutrition reduces parenteral nutrition associated cholestatic liver disease, a common side effect of parenteral nutrition.
Biliary atresia, idiopathic neonatal hepatitis, and specific genetic cholestatic conditions are the most common causes of jaundice and hyperbilirubinemia that continue beyond the newborn period. The long term goal of the Childhood Liver Disease Research Network (ChiLDReN) is to establish a database of clinical information and plasma, serum, and tissue samples from cholestatic children to facilitate research and to perform clinical, epidemiological and therapeutic trials in these important pediatric liver diseases.
