Filter by:The purpose of this study is to determine the effectiveness and safety of mitomycin C in the treatment of primary sclerosing cholangitis (PSC).
The purpose of this study is to evaluate whether simtuzumab (GS-6624) is effective at preventing the progression of liver fibrosis in adults with primary sclerosing cholangitis (PSC).
This study aim to prospectively evaluate the clinical utility of Spyglass in sclerosing cholangitis patients undergoing endoscopic retrograde cholangiopancreaticography (ERCP). Fifty patients with a definite diagnosis of sclerosing cholangitis and a clinical indication for ERCP from September 2008 and onwards will be investigated with peroral cholangioscopy using Spyglass direct visualization system. Clinical data on all patients will be collected at time of the ERCP including information on the Primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD), serum liver function tests and indication for ERCP. A structured data collection form including information on Majoie Score, macroscopic features of the bile ducts at cholangioscopy, quality of the investigation, technical difficulties, and an overall judgment of whether any abnormalities observed were benign or malignant was completed by the endoscopist in conjunction with the procedure.
Primary sclerosing cholangitis (PSC) is a rare chronic cholestatic liver disease, typically affecting middle aged men and is frequently associated with inflammatory bowel disease. Establishing diagnosis in early stages of cholestatic hepatopathy is still a clinical challenge and based on invasive diagnostic procedures: endoscopic retrograde cholangiography (ERC) or percutaneous liver biopsy are needed when magnetic resonance cholangiopancreaticography remains inconclusive. As these procedures are associated with significant risks for the patient, the goal of this study is to evaluate, if endoscopic ultrasound (EUS) of the biliary tract is a useful diagnostic tool in suspected PSC.
Single-arm pilot clinical trial. Patients with non operable CC associated with PSC will be subjected to liver transplantation after a neoadjuvant multimodal therapy protocol. Cholangiocarcinoma (CC) accounts for 3% of all gastrointestinal cancers; it is more frequent in patients with primary sclerosing cholangitis (PSC), who carry an 8%-12% risk of developing this type of neoplasm. Only a minority of patients are suitable for resection partly because of the anatomic position of the tumor (which often arises from the bile duct bifurcation) and partly because of the frequently coexisting liver disease. In fact, CC is currently considered a major contraindication to liver transplantation (OLT) at the majority of centers, given a 5-year survival rate of 0%-35%. New strategies have been developed for the treatment of this kind of cancer arising in PSC. The Nebraska University group showed a 1 and 3 years survival of 55 and 45 % combining a neoadjuvant intra bile duct barchytherapy and 5-FU based chemotherapy with liver transplantation. University of Pittsburg proposed also a neoadjuvant protocol prior to liver transplantation based on systemic chemotherapy and external radiotherapy reporting a 53% 5 years survival. More convincing results come from the Mayo Clinic. An accurate selection of patients and a proper neoadjuvant multimodal therapy (chemotherapy, external radiotherapy and intraluminal bile duct brachytherapy) lead to a 80% 5 years survival after liver transplantation.
The purpose of this research study is to determine whether the combination of UDCA and ATRA taken for 3 months will improve laboratory tests of liver and bile duct inflammation in patients with Primary Sclerosing Cholangitis (PSC). Our hypothesis is that a combination of these medications will improve the liver inflammatory tests in these patients, specifically a reduction in alkaline phosphatase (AP) by at least 30%.
Our institution performs therapeutic ERCP (Endoscopic retrograde cholangiopancreatography ), Endoscopic Ultrasound (EUS) and Interventional Endoscopy in around 1000 patients a year. Procedures such as biliary and/or pancreatic sphincterotomy, stents placement (metallic or plastic) and removal for revision, cysts and pseudocysts drainage are conducted in patients suffering from pancreatico-biliary disorders, gastrointestinal disorders and esophageal disorders. The investigators would like to assess prospectively the efficacy and safety of these routine procedures to permit identification of technical details about the procedures or other factors which might be associated with outcome or results. Assessment of these details would help us with problem identification and recommendations to improve health outcomes and quality of life in these patients.
Primary sclerosing cholangitis (PSC) is a chronic inflammatory disease of the biliary tract of unknown origin. Around 50% of patients develop during their disease course narrowing of the main bile duct with corresponding increase in symptoms such as itching, jaundice and abdominal pain. These narrowings can be treated by balloon dilatation or temporary insertion of a plastic endoprosthesis. However, it is not known which of these two therapeutic modalities is best. This study aims to compare both techniques in order to determine which is best in terms of postponing recurrence of the narrowing, safety and costs.
This study will collect data from patients undergoing an ERCP procedure with probe-based Confocal Laser Endomicroscopy for suspicion of bile duct cancer. the objective is to evaluate the diagnostic performance of pCLE for the diagnosis of indeterminate biliary stricture when associated with other diagnostic information (standard ERCP and tissue sampling).
The goals of the proposed work are two fold: Firstly, to see if the antibiotic vancomycin may be used for the early treatment of Biliary Atresia (BA) and Primary Sclerosing Cholangitis (PSC). The investigators hope to learn what effect Vancomycin has on the bacteria that are present in stool, body fluid or intestinal tissue on someone who has BA and PSC and if so by what mechanism. Secondly, the investigators hope to learn to characterize human intestinal microbial communities (microbiome: the collection or collectivity of microorganisms) using molecular methods, examine the mechanisms of interaction between host and microbiome using genomic approaches, and determine how the microbiome both preserves local health and promotes pathology. The investigators will focus on primary sclerosing cholangitis, biliary atresia, as well as states of health. The composition of the associated microbiome will be assessed based on ribosomal DNA and RNA sequences, and attention will be given to richness (diversity), evenness (relative abundance), and variation with respect to time, person, and anatomic niche. Host response at the adjacent mucosal surface will be assessed based on genome-wide gene expression patterns.
