Background Feasibility of antireflux metal stent (ARMS), designed to prevent duodenobiliary
reflux, was reported in patients with distal malignant biliary obstruction. In this prospective …

Methods Patients with nonresectable distal malignant biliary obstruction were identified
between April and December 2014 at three Japanese tertiary centers. We retrospectively …

Background and Aim An antireflux metal stent (ARMS) for nonresectable distal malignant
biliary obstruction (MBO) may prevent recurrent biliary obstruction (RBO) as a result of …

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 and Aims In patients with unresectable distal malignant biliary obstruction
(MBO), endoscopic biliary drainage by using self-expandable metal stents (SEMSs) is an …

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 …

Endoscopic retrograde cholangiopancreatography with stent placement has been utilized as
standard palliative management of distal malignant biliary obstruction (MBO). Compared to …

An antireflux metal stent (ARMS) for distal malignant biliary obstruction has been reported to
be useful, but the effectiveness of a flared-end structure to prevent migration on ARMS …

Objectives Anti‐reflux metal stent (ARMS) has been used to prevent recurrent biliary
obstruction (RBO) due to sludge formation or food impaction. However, the most suitable …

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 …
