Active clinical trials for "Cholangitis"

Nalfurafine hydrochloride is a selective kappa-opioid receptor agonist developed in Japan, and in May 2015 the use of nalfurafine hydrochloride was officially approved in Japan for pruritus in patients with chronic liver diseases including PBC. In the current study, the investigators aimed to assess pruritus and overall QOL before and after administration of nalfurafine hydrochloride in patients with PBC. Furthermore, the investigators took serum sample from the enrolled patients and examine the association of pruritus with possible biomarkers.

Primary sclerosing cholangitis (PSC) Prospectively validate interpretation criteria for the characterization of PSC strictures Prospectively evaluate the accuracy of pCLE for the characterization of PSC strictures (differentiation between malignant vs. non malignant strictures), using the newly developed interpretation criteria Evaluate the feasibility and safety of pCLE for the characterization of PSC strictures

Evaluation of the efficacy of laser-based endomicroscopy as a complement to white-light colonoscopy and chromoendoscopy for early detection of colon dysplasia in patients with PSC-IBD. White-light colonoscopy is a routinely used procedure in colorectal cancer surveillance programs. However, it does not permit detection of early dysplastic lesions. Chromoendoscopy by applying a dye (indigo-carmine) through the colonoscope helps to identify flat lesions but is not suitable for accurate endoscopic diagnosis of dysplasia and intraepithelial neoplasia Under this aim we will perform a clinical study evaluating a newly developed technique allowing for in vivo confocal microscopy assessment of the colon mucosa using laser-based endomicroscopy together with intravenous administration of fluorescein (FITC).

We wish to develop a protocol for PET/CT examination of humans using the bile acid tracer 11C-cholylsarcosine. This is done by a series of PET/CT examinations of healthy humans and patients with cholestatic disorders.

We do ERCP procedure (Endoscopic procedure with the help of x-rays) for a variety of reasons such as bile duct stones, bile duct obstruction secondary to bile duct narrowing (Strictures) and for bile leak. The incidence of infection post ERCP is around one in 200. There are some group of patients where this risk is significantly increased. In this high risk group, the risk increases from 1 in 75 to in some diseases 1 in 15 (Described in PIS). There are some reports that some of the infection may be contributed by contamination of bacteria in the scope. This happens even after diligently sterilizing the scope. A multi-centre study reported that the risk of contamination is as high as 39% but what we do not know is how many resulted in bacterial infection. We do not know what percentage of infection is secondary to the above. The new single use duodenoscope has been introduced in to the market to minimise the risk of post ERCP infection. It is CE marked and a single centre study reported that the above performance of the above scope was comparable to the standard reusable scope. We want to assess the scope simultaneously in multiple different hospitals. In addition, we also want to assess the cost consequence to the NHS for using the above scope. Hence we want to assess the performance of the scope in the high risk groups for infection.

The purpose of this study is to assess the healthcare-related quality of life (HRQOL), the impact of risk of liver transplant and risk of malignancy on HRQOL, and the complementary and alternative medicine use in patients with PSC.

To demonstrate the clinical utility of the addition of per oral cholangioscopy (POCS) to standard endoscopic retrograde cholangiopancreatography (ERCP) with brushing cytology for diagnosis and early detection of cholangiocarcinoma in patients diagnosed with primary sclerosing cholangitis (PSC).

Today 11 percent of China's population is over the age of 65, and according to United Nations, it will take China just 20 years for the proportion of the elderly population to double to 25%. As life expectancy has increased, application of Endoscopic Retrograde Cholangiopancreatography (ERCP) in super-aged (≥80 years of age) is no longer limited with increasing prevalence of choledocholithiasis, and malignancy in advancing age. This increasing may come with more difficulty in cannulation or more complications in senior patients. Regarding difficult cannulation, little is known about grading difficulty in the elderly and its relation with adverse events. Therefore, it is time to evaluate the risk factors of adverse events in super-aged patients with difficult bile duct cannulation.

This is an observational, retrospective cohort study of patients with primary biliary cholangitis (PBC) who failed ursodeoxycholic acid (UDCA) treatment, using a real-world data source, the Komodo Health United States (US) claims database. The study is designed to evaluate the effectiveness of obeticholic acid (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.

In this study, investigators aim to explore the status of advanced endoscopy in different endoscopy units all over the world.
