Active clinical trials for "Bile Duct Diseases"

This trial determines the feasibility of Laryngeal Mask Airway Gastro (Laryngeal Mask Airway) when used on patients who are undergoing endoscopic retrograde cholangiopancreatography for pancreas and bile duct disorders. Laryngeal Mask Airway is a device that helps patients breathe while they are asleep during procedures.

Patients with malignant obstructive jaundice (cancer of head of pancreas and cholangiocarcinoma) generally have a very poor prognosis with less than 20% patients having resectable disease at presentation. These patients also have a very poor quality of life with a life expectancy of 6-8 months. Jaundice associated with pruritus, poor appetite, malabsorption and loss of weight and cholangitis is the most common and troublesome problem. Placement of metallic stents has been the standard of care for patients with unresectable disease. However, about 50% of these stents get blocked in 6-8 months. Use of endoscopic Radio-frequency Ablation (RFA) prior to placement of metal stents may increase the patency of these stents

The aim of the present study was to compare the efficacy and safety of the knob-tipped knife and needle knife for precut papillotomy in difficult common bile duct (CBD)cannulation.

Difficult cannulation of the common bile duct is encountered in about 10%of ERCP procedures. This frequently happens in the form of repeated unintentional cannulation of the pancreatic duct. Two valid options are available to facilitate cannulation at this point: Double guidewire technique or performing a transpancreatic precut. This is a randomized trial comparing the efficacy and Safety of double guidwire technique versus transpancreatic precut after three unintentional passages of the guidewire into the pancreatic duct.

The purpose of this study is to determine if the double guide wire technique is more effective than the conventional method in those cases of difficult selective biliary cannulation in the ERCP procedures.

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 and pancreatic duct cannulation in patients. The primary outcome was successful deep bile duct cannulation and pancreatic duct canulation. The second outcome was the major papillary orifice,bile juice flow from the papilla, time to achieve deep bile duct cannulation, fluoroscopy time for deep bile duct cannulation,the appearance of the major and minor papillary orifice, pancreatic juice flow from the papilla, time to achieve deep pancreatic duct cannulation, and fluoroscopy time for deep pancreatic duct cannulation in the pinaverium bromide group versus Vitamin C group.

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

A previous study evaluating the NvisionVLE® Imaging Low Profile System revealed the system to be feasible and safe for use in bile duct. The study also revealed a potential to better define abnormalities, target sampling and therapy when utilizing the NvisionVLE® Imaging Low Profile System. This study will further evaluate the safety and efficacy of the NvisionVLE® Imaging Low Profile System in patients with bile duct diseases.

The study aims to evaluate factors associated with an increased risk of procedure related adverse events (including tecnical failure) of endoscopic retrograde cholangiopancreatography procedures (ERCP) conducted in a teaching setting, with trainee involvement.

Precut-sphincterotomy is a well established alternative after repeated futile attempts for common bile duct (CBD) cannulation with standard catheters and/or guide-wires fail. Commonly used devices instruments for pre-cutting are the needle-knife and the Erlangen-type precut-sphincterotome. In 1996 a so called "baby-sphincterotome" (Easy-Cut®, MTW, Wesel, Germany) with a pre-shaped-bended (to facilitate biliary access) small-calibre 3-French tip was developed, which enables cannulation and pre-cutting in one step. Here the investigators report on the clinical evaluation of this device.
