BACKGROUND AND STUDY AIMS The widespread use of cholangioscopy in the management of difficult choledocholithiasis has been limited by the need for two expert operators. This report describes the use of a technique of single-operator duodenoscope-assisted cholangioscopy (SODAC) in the successful management of 75 patients with choledocholithiasis. PATIENTS(More)
BACKGROUND The most common complication of uncovered biliary self-expandable metal stents (SEMSs) is tumor ingrowth. The addition of an impenetrable covering may prolong stent patency. OBJECTIVE To compare stent patency between uncovered and partially covered SEMSs in malignant biliary obstruction. DESIGN Multicenter randomized trial. SETTING Four(More)
BACKGROUND The aim of this study was to identify predictors of outcome after pancreatic duct stent placement for duct disruption. METHODS Patients were identified from endoscopy databases. Disruption was defined by extravasation of contrast from the pancreatic duct during endoscopic retrograde pancreatography. Data collected included demographic(More)
Alendronate sodium, an aminobiphosphonate used primarily to treat osteoporosis in postmenopausal women, is known to cause esophagitis. A 71-year-old woman experienced severe, acute esophagitis and severe stricture of the esophagus due to oral alendronate therapy. Unlike in previous cases, she had taken alendronate for 10 months before the onset of(More)
BACKGROUND AND STUDY AIMS Angiographic and surgical therapy are standards of care for persistent diverticular bleeding. Colonoscopic intervention using epinephrine injection, multipolar electrocautery, and placement of an Endoclip has not gained widespread acceptance due to concerns about complications,and the widespread management of severe lower(More)
Duodenoscope assisted cholangiopancreatoscopy allows direct visualization of the pancreatic duct and bile duct. There are several circumstances where direct ductal visualization might be helpful in clarifying a diagnosis or providing targeted treatment. Duodenoscope assisted cholangiopancreatoscopy is currently employed for a variety of indications(More)
The safety and efficacy of pulsed tunable dye laser fragmentation of common bile duct stones was assessed in pigs. Laser pulses were conducted through a flexible quartz fiber that was in direct contact with stones that had been surgically implanted into the common bile duct. All calculi were rapidly fragmented into small pieces without significant damage to(More)
