Metal Stents (Moving Cell Stent) for Inoperable Tumors of the Bile Duct Tract

In this feasibility study (non-randomized), the applicability of a new "moving cell" biliary stents (by HILZO) in Klatskin tumors (bile duct obstruction) will be investigated. The HILZO Moving-Cell Stent to be examined here is a non-coated metal stent with a novelty. The meshes have a diameter of 4 mm, which is rather small compared to most other stents. This significantly increases the radial force and thus the stability of the stent. Furthermore, ingrowth by tumors in the st...

Study of Microbiota in Bile From Patients With Common Bile Duct Stone During ERCP

In this study, investigators will investigate the microbiota of bile in common bile duct stone participants. Three key questions are of concern. The first one is whether there is bacteriria in bile in participants without common bile duct stone. The second one is whether the microbiota of bile is similar with that of gut mucosa in common bile duct stone participants. The third one is whether the bacteria in bile of common bile participants with intact papillar is the same as th...

RCT of the Double Wire Technique With or Without Transpancreatic Sphincterotomy for Difficult Common Bile Duct Cannulation

Endoscopic cholangiography is a procedure which is performed to image the bile duct and perform therapy like removal of bile duct stones. It is currently standard of care to remove stones from the bile duct when found as they frequently cause complications like infections which can sometime be life threatening. Therapy on the biliary tree, like for example stone removal, frequently requires inserting tools through the opening of the duct and cutting of the muscle which control...

Impact of Pinaverium Bromide on Bile Duct Cannulation During Endoscopic Retrograde Cholangiopancreatography

Pinaverium bromide can be used to treat symptoms related to irritable bowel syndrome (IBS) and functional disorders of the biliary tract. In this study, pinaverium bromide was compared with Vitamin C for the facilitation of bile duct cannulation in patients. The primary outcome was successful deep bile duct cannulation. The second outcome was the major papillary orifice, bile juice flow from the papilla, time to achieve deep bile duct cannulation, and fluoroscopy time for deep ...

Microbiomes in Patients of Recurrent Common Bile Duct Stones

Bile duct stones is a common biliary tract disease, which is characterized by high morbidity and frequent recurrence. Endoscopic retrograde cholangiopancreatography (ERCP) is an effective therapy for common bile duct stones, and endoscopic sphincterotomy (EST) which associated with recurrent cholangiolithiasis often carried out on difficult intubation or extracting stones, probably due to enhanced reflux of intestinal contents that changes the microenvironment. Patients with ch...

Fully Covered SEMS Versus Partially Covered SEMS With Anti-migration System for Malignant Distal Biliary Obstruction

The purpose of this study is to compare the duration of stent patency between partially covered and fully covered SEMS for palliation of malignant distal bile duct obstruction.

Study Investigating the Best Method of Treatment of Bile Duct Stones in Higher Risk Patients

The aim of the trial is to compare two operations which are used to treat bile duct stones. The hypothesis of the study is that there is no difference between endoscopic sphincterotomy followed by laparoscopic cholecystectomy or laparoscopic bile duct exploration during laparoscopic cholecystectomy in the treatment of bile duct stones in higher risk patients.

PTFE Covered Stents Versus Naked Stents in the TIPS (Transjugular Intra-Hepatic Porto-Systemic Shunt)

Transjugular intrahepatic portosystemic shunts (TIPS) have been increasingly used for the treatment of complications of portal hypertension in patients with cirrhosis. The initial experiment of the TIPS was reported during the 1990s with stents of various brands, manufacture and sizes, but all "non covered", thus owing the pseudointimal hyperplasia growing inside the stent, which progressively decreases the diameter of the shunt and thus its efficacy. Since the beginning of th...
