Active clinical trials for "Jaundice, Obstructive"

Data accumulated from medical record collected from January 2008 until December 2018

The main objective of the study is to evaluate the size of the common bile duct (CBD) in a large cohort of patients with jaundice secondary to pancreatic head or distal bile duct malignancy undergoing diagnostic EUS for tissue acquisition or evaluation of resectability and to establish factors associated with a dilation of the CBD greater than 15mm.

To assess the size of the common bile duct in a large cohort of patients with jaundice following a malignant tumor of the head of the pancreas or the distal bile duct receiving a diagnostic EA for biopsy and / or for evaluation of tissue resectability.

Patients with obstructive jaundice (OJ) often require surgical, endoscopic or radiological interventions to facilitate biliary drainage and relieve jaundice. However it is known that patients with OJ have increased surgical risks than non-jaundiced patients undergoing the same procedures. Surgery for severe OJ is associated with a significant post-operative mortality (10-15%) and morbidity (30-65%). The commonest complications are related to sepsis but the pathophysiological mechanisms behind this susceptibility to bacterial infection are not clear. Recent work has shown a pivotal role of bile in the maintenance of enterocyte tight junctions and the expression of tight junction-associated proteins which could account for the translocation of enteric bacteria and bacterial products to mesenteric lymph node complexes, the portal circulation and subsequently the liver. Some of these bacterial products, such as endotoxin and quorum sensing signalling molecules (QSSMs), have immunomodulatory properties which may dampen normal immune responses to infection resulting in life-threatening organ dysfunction. Bacterial endotoxin and quorum sensing signalling molecules (QSSMs) represent good candidates for the mediators of this immune suppression and although there is a compelling case for their involvement in the pathogenesis of sepsis, evidence to support their involvement in the aetiology of infection in OJ is currently lacking.

This study is designed to evaluate the efficacy and safety of the combination treatment of Huaier granule and biliary drainage for malignant obstructive jaundice.

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.

The purpose of this study is to detect differences in the enzymatic activity of matrix metalloproteinases in patients with malignant obstructive hyperbilirubinemia before and after percutaneous biliary drainage.

This retrospective monocentric study aims at comparing multimodality endoscopic biliary drainage versus percutaneous radiologic biliary drainage in case of perihilar malignant obstruction. Data from patients admitted in the Nancy University Hospital, France, between january 2016 and march 2022 with jaundice and perihilar obstruction will be retrospectively collected.

To investigate the influence of antibiotics on the incidence of biliary tract infections after PTCD for malignant obstructive jaundice.
