Active clinical trials for "Cholangitis"

Primary Objective: To document state-of- the-art multi-modality management of occluded biliary SEMS aiming to minimize number of reinterventions while providing symptom relief without procedure-related serious adverse events. NOTE: This study will be hypothesis-generating for an anticipated randomized controlled study (RCT) to compare outcomes of placement of a plastic stent inside the occluded SEMS to outcomes of the proposed multi-modality approach.

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).

Cholangitis is a complication of biliary statsis. Bile juice is sterile when there is no obstruction, however, it can be infected with bacteria when there is a stasis or obstruction. After infection, cholangitis can be developed because of systematic endotoxemia or bacteremia. Though identification of bacteria is very important for selection of adequate antibiotics, treatment with empirical antibiotics is commonly performed when identification of bacteria is not possible. Identification of bacteria is usually done with blood or bile culture. In the previous studies, the same results from blood and bile were common in patients with cholangitis. However, the data of these studies were based on the bile juice which was aspirated by surgery. Considering that bile duct obstruction is usually treated with endoscopy or radiological intervention without surgery, it is necessary to collect data with endoscopic or radiologic intervention. In addition, the concordant rate of these two tests has not been reported according to severity of cholangitis. As a result, the necessities of bile and blood culture are not agreed among experts in this fields. Our hypothesis is that concordant rates of bile and blood culture are same in patients with each moderate or severe cholangitis. However, the concordant rates of bile and blood culture are different between patients with moderate and severe cholangitis. This study will assess the positive rates of blood and bile culture in patients with moderate or severe cholangitis, respectively and compare the results according to the different severity.

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a lengthy and uncomfortable procedure that requires adequate sedation. Propofol is the commonly used sedative during ERCP. However, dose dependent cardiac and respiratory depression may occur. Hypotension usually occurs in severe cholangitis which necessitate the use of alternative sedative. The aim is to study the efficacy and safety of ketofol as a sedative during urgent ERCP for severe cholangitis.

This is a health economic study on using quantitative magnetic resonance imaging in biliary disease. It is an observational study aiming to recruit 40 patients with Primary Sclerosing Cholangitis (PSC) in 12 months. The aim of the study is to assess the effect of result of enhanced Magnetic Resonance Cholangiopancreatography (MRCP+) on the physicians' diagnosis and/or plans for patients with suspected or confirmed PSC, compared with usual standard of care. This study also aims to identify the cost-effectiveness of adding MRCP+ to the standard care pathway.

This is an observational, retrospective cohort study, using the UK PBC registry, comparing patients with primary biliary cholangitis (PBC) who failed ursodeoxycholic acid (UDCA) treatment and were treated with obeticholic acid (OCA) to patients with PBC who failed UDCA treatment and were not treated with second-line therapy. The study is designed to evaluate the effectiveness of OCA. All patients who meet diagnostic criteria for PBC in the database between 01 Jun 2015 and 31 Dec 2021 and who meet all eligibility criteria will be considered for this study.

Analysis of occurrence of SSC-COVID in SARS-CoV-2-patients after the first wave of COVID-pandemic

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.

Primary sclerosing cholangitis (PSC) occurs in approximately 10 % of patients with ulcerative colitis (UC), but the outcome of reconstructive surgery is not clear. The purpose of this study was to determine the functional outcome after surgery, frequency of pouchitis, complications and failure-rate in UC-PSC patients compared to patients with UC alone. Both ileal pouch-anal anastomosis (IPAA) and ileo-rectal anastomosis (IRA) were studied.

This study evaluates the different response of Ursodeoxycholic Acid in primary biliary cholangitis only and primary biliary cholangitis with high immune globulin G or aminotransferase at West China Hospital from 2008-2017.
