This study aims to evaluate the usefulness of disposable digital single-operator cholangioscopy (SOC) and intraductal ultrasound (IDUS) for the accurate diagnosis of indeterminate biliary stricture.
This study hopes identify the main pruritogens of ICP pruritus and provide new insights for the diagnosis, prediction, and treatment of ICP. Details are as follows: It is planned to include ICP confirmed pregnant women and healthy pregnant women who have given birth in the Peking University Third Hospital and Sichuan University West China Second University Hospital. Then progesterone sulfate levels in plasma samples will be quantified by High Performance Liquid Chromatography-Mass Spectrometry (HPLC-MS) and itch intensity will be quantified by questionnaires. Main study endpoint: To reveal new indicators of ICP diagnosis with high accuracy: single, multiple or combined indicators of progesterone sulfates and other molecules like bile acids; Secondary study endpoint: To determine whether progesterone sulfates can be used as an early screening indicator for ICP for disease prediction, specifically whether elevated levels of progesterone sulfates predate pruritus in pregnant women with ICP.
This study hopes investigate the itch-inducing ability of different potential pruritogen candidates of cholestasis pruritus, especially the intrahepatic cholestasis of pregnancy (ICP). In this study, a combination of skin application and needle-free subcutaneous injection was used to investigate whether human endogenous molecules can cause itching. And a questionnaire is used to quantify the intensity of different candidates-induced itch.
Migration of stones from the gallbladder to the common bile duct (CBD) facilitated by gallbladder contractions can be listed as a complication of gallstones disease. In the case of common bile duct stone (CBDs) migration, an endoscopic cholangiopancreatography (ERCP) should be offered for both symptomatic and asymptomatic patients fit for the procedure. An ERCP with an adequate endoscopic sphincterotomy obtains a complete biliary clearance in about 80-90% of the patients[5]. Whilst most cases are successfully treated with such first-line approaches, about 10-15% need alternative and/or adjunctive techniques to achieve bile duct clearance. These conditions are generally defined as "difficult" bile duct stones, a broad category of cases that encompasses very different scenarios. In the case of irretrievable CBDs, the European Society of Gastrointestinal Endoscopy (ESGE) recommends the endoscopic placement of a temporary biliary plastic stent to warrant biliary drainage. Since their introduction, fully covered self-expanding metal stents (FCSEMS) have rapidly been adopted for the treatment of benign biliary conditions such as strictures, leaks, or bleeding. In a recent retrospective study it has been shown that FCSEMS are useful in the approach of difficult lithiasis of CBD with no significant adverse events associated. Moreover, a promising FC-SEMS with a particular prosthesis design (flare type - Niti-S "S-Type" Taewoong) could be even more useful since it reduces the frequent complication of fully covered stents which is the migration of the prosthesis. However, prospective data on the effectiveness and on the adverse events rate on the use of SEMS for incomplete stone CBDs clearance are still lacking. Therefore, the investigators aim to estimate the incidence of adverse events, complete biliary clearance, and migration rate after 3-6 month from ERCP index (stent positioning), comparing plastic stents vs FC-SEMS (Niti-S "flare type" - Taewoong).
The stool color scale was set in 2018 in the health books of French children. The study aim is to see if the scale is usefull for healthcare professionals and if this scale has advanced the detection of neonatal cholestasis.
To verify the effect of feeding milk powder rich in medium chain fatty acids on improving the nutritional status and disease status of infants with cholestatic liver disease and To evaluate the safety of feeding milk powder rich in medium chain fatty acids in infants with cholestatic liver disease.
When clinical doctors cannot diagnose the cause of biliary stricture after comprehensive laboratory and imaging examinations, it is collectively referred to as unexplained bile duct stenosis. This study intends to analyze the diagnostic value of the biliary endoscopy system for unknown cause biliary strictures , and compare the diagnostic efficacy of biopsy under biliary endoscopy guidance with brushing cytology under ERCP.
The aim of this study is to evaluate the risk factors of PNAC in neonates
There is limited knowledge about the extent of the impact of maternal metabolic diseases (MD) and/or alterations in maternal serum lipid content upon neonatal lipid distribution and phenotypes. This observational feasibility study aims to investigate the effect of maternal MD on fat distribution, lipid content and metabolic phenotype of different neonatal tissues. We will explore whether differences in tissue fat distribution and lipid content are observed in the neonates of women with MD during pregnancy, compared to those who have a healthy, uncomplicated pregnancy and if there are changes in how the different tissues work (e.g. cardiac function). If there is evidence to show that there are alterations during pregnancy in children of women with MD, this will help inform potential interventions to ensure optimal child health.
