Filter by:The aging of the population goes along with an increased demand for intensive care among very elderly patients (above 75-80 years old). At the same time, there is a decline in the supply of intensive care units (ICU). The 1-year mortality of patients above 80 years old in ICU ranged from 40 to 70%. Moreover, many survivors suffer from long-term sequelae as poor quality of life, cognitive impairment and functional disability. It is unclear under what conditions older patients may benefit from ICU admission. Cholangitis frequently occured in older patient. Moreover, severe acute cholangitis is a potentially life threatening disease characterized by a biliary obstruction and an infection of the bile possibly evolving towards systemic infection, shock and death. Because of its potential rapid reversibility of symptom thanks to early intravenous antibiotics and biliary decompression with drainage, old patients suffering from acute cholangitis are easily admitted to intensive care unit. To date, there is a lack of data about the outcome in this population admitted to the intensive care unit with acute cholangitis. The aim of the current study is to describe the outcomes in elderly patients (> 75 years old) admitted to the ICU with acute cholangitis and to identify prognostics factors associated with long term mortality (6 months).
This study aims to determine the repeatability and reproducibility of Quantitative Magnetic Resonance Cholangiopancreatography (MRCP). Imaging scientists at Perspectum Diagnostics have developed a hessian-based mathematical model to enhance conventional MRCP to a 3D geometric model of the biliary tree, 'Quantitative MRCP'. This enables advanced quantitative measurement of bile duct width, orientation, branching point and curvative metrics. The technology has been validated against 3D printed phantoms for accuracy, and early clinical research has demonstrated the technology has potential for clinical impact, with improvement in radiologist performance versus conventional non-enhanced MRCP imaging (Vikal et al 2017). Quantitative MRCP aims to act as a tool to not only improve assessment of the current status of the biliary tree, but also act as a mechanism to track change within the ducts. Thus, it must be established that any change between scans is due to change in the physiology of the individual and not due to a quirk or fault of the technology. In order to achieve this a series of scans will be performed on an individual over a short period of time, for which the condition of the biliary tree within that individual can be assumed to be constant. Between each scan, subject and coil repositioning will occur. The study will recruit a group of adult volunteers, from both diseased groups and healthy groups in order to achieve a range of physiological biliary metrics.
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.
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).
In expert comment, performing the sphincterotomy for choledocholithiasis with acute cholangitis may increase bleeding and pancreatitis risks (from 2% to 10%). Therefore, investigators often perform biliary drainage in acute stage, and arrange 2nd session ERCP for stone removal later. However, in the recent study, single-stage endoscopic treatment may be still effective (stone removal rate 90%) and safe for mild to moderate acute cholangitis associated with choledocholithiasis. Investigators will carry out a prospective trial to analyze one-stage retrograde endoscopic common bile duct stone removal in mild and moderate cholangitis with choledocholithiasis to determine the safety, successful rate, and complications in these two groups.
This study aims to prospectively assess the repeatability and reproducibility of iron-corrected T1 (cT1), T2*, and hepatic proton density fat fraction (PDFF) quantification with multiparametric MRI using the LiverMultiScan™ (LMS, Perspectum Diagnostics, Oxford, UK) protocol across different field strengths, scanner manufacturers and models.
This study evaluates the safety and efficacy of baricitinib in participants with primary biliary cholangitis (PBC) who do not respond or are unable to take ursodeoxycholic acid (UDCA).

Post-surgical biliary strictures are common especially after cholecystectomy. Standard treatment involves the performance of multiple procedures over a 1 year period at least using several plastic stents to achieve permanent dilatation of these strictures. Metallic stents have the theoretical benefit of absence of need of multiple sessions. These strictures however are frequently very close to the hilum and thus previously considered a contraindication for insertion of metallic stents for the fear of occlusion of the contralateral ducts. Metallic stent migration is also a frequent problem. The use of a metallic stent that is short and completely intraductal, in theory, should reduce the risk of stent migration. This is a randomized controlled trial comparing the efficacy and safety of a short metallic intraductal stent to the conventional treatment which is multiple plastic stents. In cases with a stricture reaching or close to the hilum a technique is used to avoid obstruction of the contralateral ducts which is insertion of a 7 French plastic stent alongside the metallic stent.
