Filter by:The aim is to compare percutaneous transhepatic biliary drainage (PTBD) with primary metal stent implantation (one stage-procedure) with PTBD with secondary metal stent implantation in terms of adverse events.
To document the clinical utility of percutaneous cholangiopancreatoscopy using a thin, disposable, flexible endoscope for evaluation and treatment of complex pancreaticobiliary disease in a prospective, multi-center case series
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 purpose of this study is to investigate the feasibility and safety of endoscopic ultrasound-guided biliary drainage with a newly designed hybrid metallic stent.
The two most commonly used methods to biopsy suspected pancreaticobiliary masses are (1) endoscopic ultrasound guided fine-needle aspiration (EUS-FNA) and (2) cytology brush biopsies obtained during endoscopic retrograde cholangiopancreatography (ERCP). At most centers, the specific method used depends on the availability of the technology and local expertise. Although it is believed that EUS-FNA is more accurate than ERCP brushings, there have been no head-to-head comparisons. The investigators' hypothesis is that EUS-FNA is superior to ERCP in obtaining tissue biopsies of pancreaticobiliary tumors, and the investigators aim to directly compare the two techniques.
The primary goal is to determine stent patency and overall survival of the conventional covered self expandable metallic stent versus paclitaxel eluting covered self expandable metallic stent in unresectable malignant bile duct stricture. The secondary goals are to assess reinterventions, complications, technical difficulties, and physician graded ease of placement and to assess toxicity of paclitaxel eluting covered self expandable metallic stent.
The primary purpose is to compare patency of two different types of biliary metal stents, i.e. covered versus uncovered Nitinella metal stent. Secondary purposes are to determine frequency of complications in the two groups, e.g. cholecystitis, pancreatitis, and cholangitis.
