Filter by:The study will evaluate the results of endoscopic treatment of NON-anastomotic biliary strictures following liver transplantation
To assess safety and effectiveness in the long term of percutaneous insertion of Biodegradable (BD) Biliary Stents for the treatment of benign biliary strictures, in a single center experience.
The Percutaneous Cholangiopancreatoscopy (PCPS) registry is an observational, multicentric, prospective, and retrospective registry of patients undergoing the percutaneous cholangiopancreatoscopy procedure at sites across the United States. In the retrospective component of the study, clinical and procedural data regarding patients who have undergone clinical indicated percutaneous cholangiopancreatoscopy procedure in the past will be collected from all the registry sites and stored in a secure database. The prospective component of the registry will run for three years at each site where patients undergoing the clinically indicated percutaneous cholangiopancreatoscopy procedure will be enrolled in the study, and the patients' data will be collected whenever the patients present to interventional radiology (IR) for a procedure or clinic visit.
The aims of this study are to compare the needle knife fistulotomy (NKF) technique versus the partial ampullary endoscopic mucosal resection (PA-EMR) technique in patients with difficult biliary cannulation and to assess the incidence rate of complications between these cannulation methods.
The aim of the study is to improve the immediate results after reconstructive and restorative operations on the biliary tract by substantiating the management of the perioperative period on the principles of "enhanced recovery after surgery".
The purpose of this study is to assess the safety, outcomes and performance characteristics of multiple biliary sampling techniques including but not limited to: single operator cholangioscopy (SOC) directed biopsies, transpapillary biliary biopsies (TPBx), brushings and bile aspiration for cytology and FISH in patients undergoing ERCP.
DNA methylation biomarker for diagnosis of cholangiocarcinoma in patients with bile duct stricture has high sensitivity and specificity compared with cytology from the brush specimens
The management of biliary strictures depends on their correct pre-operative evaluation which remains challenging. Despite the emerging multitudes of new diagnostic opportunities- modalities we have today, there is still a large number of biliary stenosis misdiagnosed with a profound negative impact on the patients´ outcome. The study aims to proove the feasibility and to evaluate the impact of Fluorescent In Situ Hybridization (FISH) on the tissue diagnostic of biliary strictures.
The aim of this prospective national multicenter randomized study is to compare, during an ERCP for VBP stenosis, the sensitivity of two biliary brushes: the INFINITY® vs the RX Cytology Brush® The main objective is the comparison of the rates of positive diagnosis of biliary brushing in cases of adenocarcinoma stenosis The total number of subjects required: 50 (25 patients per group) Duration of the inclusion period: 2 years Duration of participation for each subject: from 7 days to 12 months (in case of negative initial withdrawal) Total duration of the study: 3 years
The management of biliary strictures depends on their correct pre-operative evaluation which remains challenging. Despite the emerging multitudes of new diagnostic opportunities and modalities which exist today, there is still a large number of biliary stenosis misdiagnosed with a profound negative impact on the patients´ outcome. The study´s aim is to compare the diagnostic yield of primary peroral cholangioscopy and ERCP (with conventional sampling - brushing and forceps biopsy - completed with the FISH) in patients with suspected malignant stricture of the common bile duct and to evaluate the impact of both methods on the management of patients with biliary stricture.
