Malfunctioning Plastic Biliary Endoprosthesis: Percutaneous Transhepatic Balloon Pulling Technique
Percutaneous transhepatic removal techniques for malfunctioning plastic biliary endoprosthesis are considered safe and efficient second-line strategies, when endoscopic procedures are not feasible. We describe the percutaneous transhepatic balloon pulling technique in a patient with an unresectable malignant hilar cholangiocarcinoma.
متن کاملPercutaneous Biliary Drainage Using Open Cell Stents for Malignant Biliary Hilar Obstruction
OBJECTIVE To evaluate the feasibility, safety and the effectiveness of the complex assembly of open cell nitinol stents for biliary hilar malignancy. MATERIALS AND METHODS During the 10 month period between January and October 2007, 26 consecutive patients with malignant biliary hilar obstruction underwent percutaneous insertion of open cell design nitinol stents. Four types of stent placemen...
متن کاملPercutaneous transhepatic self-expanding metal stents for palliation of malignant biliary obstruction.
BACKGROUND Malignant biliary obstruction is often inoperable at presentation and has a poor prognosis. Percutaneously placed self-expanding metal stents (SEMS) have been widely used for palliation of malignant biliary obstruction as an alternative to major bypass surgery or when endoscopic drainage is not technically feasible. The success rate, procedural complications and outcomes in patients ...
متن کاملPercutaneous stent placement for the treatment of malignant biliary obstruction: nitinol versus elgiloy stents
OBJECTIVE This study aimed to compare two self-expanding stents, a nitinol stent and an elgiloy stent, both placed percutaneously, in terms of their efficacy in palliating inoperable malignant biliary obstruction. MATERIALS AND METHODS We retrospectively investigated 99 patients with unresectable malignant biliary obstruction treated with percutaneous placement of a self-expanding metallic st...
متن کاملHistologic assessment of biliary obstruction with different percutaneous endoluminal techniques
BACKGROUND: Despite the sophisticated cross sectional image techniques currently available, a number of biliary stenosis or obstructions remain of an uncertain nature. In these pathological conditions, an "intrinsic" parietal alteration is the cause of biliary obstruction and it is very difficult to differentiate benign from malignant lesions using cross-sectional imaging procedures alone. We e...
