The “U-wire” technique during ERCP for easy guide wire passage through occluded uncovered metal stents

The "U-wire" technique during ERCP for easy guide wire passage through occluded uncovered metal stents.

A significant number of self-expanding metal stents (SEMSs) placed as conservative therapy for malignant biliary obstruction will become occluded [1]. Stent occlusion can be treated endoscopically either by balloon trawling to remove the biliary sludge and debris or by inserting a polyethylene stent or a second stent through the occluded stent [2]. However, these treatments can be given only af...

Two techniques for guide wire advancement along a tortuous pancreatic duct: the through-the-stent and flipped "U-wire" techniques.

a tortuous pancreatic duct: the through-the-stent and flipped “U-wire” techniques A 52-year-old man with a history of renal transplantation, immunosuppression, and valvular heart disease developed severe acute pancreatitis with a pancreatic pseudocyst. Endoscopic retrograde cholangiopancreatography (ERCP) performed 6 weeks previously had revealed a large pancreatic duct leak requiring the place...

Guide wire-assisted technique to access the bile duct with biopsy forceps for repositioning and removal of metal stents.

The malposition of a self-expandable metal stent (SEMS) placed fully inside the bile duct may be disastrous, and adjusting the position of a malpositioned stent can be difficult or impossible. Fully-covered SEMSs were designed mainly to treat benign biliary strictures and to be removable [1]. The removal process can however be difficult if the stent is placed fully inside the bile duct.
