Active clinical trials for "Bile Duct Diseases"

This registry is to evaluate the procedural and clinical outcomes in patients undergoing endoscopic treatment of bile duct stones when utilizing an algorithmic management approach.

The aim of this study is to evaluate the usefulness of a newly developed multibending ultra-slim upper endoscope for the successful direct peroral cholangioscopy (POC) without assisting accessory in comparison with conventional ultra-slim endoscope. The investigators expect that multibending endoscope will show more higher successful performance than conventional endoscope.

It is reported in the literature that the treatment of any liver and bile duct disease process, whether benign or malignant, continues to be a huge challenge. For example, patients with adenocarcinoma continue to be diagnosed at an advanced stage with medical and surgical options that are improving in terms of outcome measurements but with much more room for improvement. Our goal is to continue to review our treatment outcomes to further improve overall survival, overall symptom control, mortality and morbidity. The main aim of this study is to evaluate and compare the outcomes from our multiple treatments of benign or malignant liver and bile duct diseases.

Retrospective study of all patients diagnosed with primary biliary cholangitis during January 2001 to July 2016 at West China Hospital by review of medical records. The following variables will be retrospectively studied: age, sex, first symptoms, clinical characteristics, pathology, treatment, stage, complications of cirrhosis, other autoimmune diseases and long-term outcome.

Digital single-operator cholangioscopy (DSOC) findings achieve high diagnostic accuracy for neoplastic bile duct lesions. To date, there is not a universally accepted DSOC classification. Endoscopists' Intra and interobserver agreements vary widely. Cholangiocarcinoma (CCA) assessment through artificial intelligence (AI) tools is almost exclusively for intrahepatic CCA (iCCA). Therefore, more AI tools are necessary for assessing extrahepatic neoplastic bile duct lesions. In Ecuador, the investigators have recently proposed an AI model to classify bile duct lesions during real-time DSOC, which accurately detected malignancy patterns. This research pursues a clinical validation of our AI model for distinguishing between neoplastic and non-neoplastic bile duct lesions, compared with high DSOC experienced endoscopists.

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 biliary and pancreatic tumors are rare but the prognosis is pejorative. It was difficult to have histology of these tumors as the samples taken during ERCP were performed under " blind " radiology control. So the diagnostic accuracy was insufficient. The arrival of A new optic fiber endoscope used by only one operator had improved the diagnostic of bilio-pancreatic diseases. However this technology with optic fiber quickly had proved outdated for several reasons: poor manoeuvrability, perfectible optical vision, optical fibers fragility and cost. A new generation of endoscopes with digital vision appeared and would allow an increase in diagnostic accuracy related to better vision and manoeuvrability. The purpose of the study is to assess the interest of the cholangio pancreatoscopy performed with digital vision.

In this prospective study the investigators compared common bile duct injuries (CBDI) following laparoscopic cholecystectomy (LC) and open cholecystectomy (OC) procedures, 35 patients in each group. To date, no detailed study concerning this matter has been published. LC - CBDI in comparison with OC - CBDI more often concerned young females with a narrow CBD, they were located closer to the liver hilus, and they were more extended.

The purpose of this study is to assess the interobserver agreement (IOV) for pancreatico-biliary Volumetric Laser Endomicroscopy (VLE) de-identified clips using the new VLE criteria. This is an Interobserver study to validate VLE criteria for indeterminate biliary and pancreatic duct strictures and evaluate impact on clinical management.
