Although self-expandable metallic stent (SEMS) has a longer patency than plastic stent (PS) for malignant biliary obstruction, stent occlusion can occur and drainage has to be reestablished in a patient with expected long survival. However, the choices are still controversial among restenting with SEMS, PS, and percutaneous transhepatic biliary drainage ...

BACKGROUND: Endoscopic palliation in malignant hilar biliary obstruction requires endoscopic retrograde cholangiopancreatography (ERCP), whereas contrast injection leads to cholangitis. Contrast-free metal stenting with or without magnetic resonance cholangiopancreatography (MRCP) has shown encouraging results, but MRCP and metal stents are costly. There have been no reports on the use of air ...

PURPOSE: Ureteral stents are commonly used to facilitate kidney drainage but they may produce significant stent symptoms and morbidity, and require a secondary procedure for removal. Previous biodegradable stents showed bio-incompatibility or inconsistent degradation, requiring extra procedures to remove undegraded stent fragments. We previously reported a first generation biodegradable stent ...

Surgery often requires the interruption of standard dual antiplatelet therapy using aspirin and clopidogrel. Here, we present three patients who underwent surgery and suffered from a perioperative stent thrombosis associated with premature discontinuation of dual antiplatelet therapy. Although there are missing evidence-based data and key guidelines, we suggest that patients ...

Endoscopic biliary drainage is the mainstay of palliative treatment in patients with unresectable malignant hilar biliary obstruction. While self-expandable metal stents have shown significant advantages in distal tumors, bilateral hilar stenting is technically demanding. Moreover, ingrowth is a significant problem in uncovered stents. We evaluated the feasibility and efficacy of ...
Uchida Yasuto - - 2010
BACKGROUND: It is said that the chronic outcomes of the two-stent technique for bifurcation lesions are inferior to that of cross-over single stenting. However, there are many cases where true bifurcations are difficult to treat by single stenting and, in particular, strategies for bifurcation lesions that are not left main ...
