Biliary drainage in malignant biliary obstruction improves patient survival and quality of life.
Although bypass surgery was historically the main method of treating malignant biliary …

Endoscopic insertion of plastic or metal stents is a wellestablished treatment for malignant
biliary obstruction. The major limitation of this technique is stent occlusion. Duodenobiliary …

BACKGROUND:: Antireflux stents that prevent duodenal biliary reflux may improve biliary
drainage and prolong stent patency. However, the use of antireflux metal stents (ARMSs) in …

Background and Aim Transpapillary stent insertion is the standard treatment for palliating
malignant biliary obstruction. However, luminal occlusion often occurs due to sludge …

Aim Antireflux plastic biliary stents prevent duodenal biliary reflux and improve the stent
patency rate. However, the efficacy of the antireflux valve in a self‐expandable metal stent …

BACKGROUND: The mechanisms leading to occlusion of plastic biliary stents (PBS) are not
known. OBJECTIVE: To evaluate the impact of reducing duodenobiliary reflux on stent …

Objectives. To compare the use of an antireflux metal stent (ARMS) with that of a
conventional covered self‐expandable metal stent (c‐CSEMS) for initial stenting of …

Introduction In unresectable malignant bile duct obstruction, endoscopic stent insertion is the
treatment of choice. However, the current stent allows only mechanical palliation of the …

Background There is as yet no ideal design of a plastic biliary stent with the longest patency
period. Objective To study the safety and effective patency period of a new plastic antireflux …

Background Self-expandable metallic stent (SEMS) placement has been a well-established
treatment for unresectable biliary tumors. Cholangitis following stenting, however, ranged …
