Background The placement of a self-expandable metallic stent (SEMS) is a widely used
nonsurgical treatment method in patients with unresectable malignant biliary obstructions …

BACKGROUND: In unresectable malignant biliary obstruction, stent insertion can be the
treatment of choice. However, metal stents are susceptible to occlusion by tumor ingrowth or …

Methods This study was initially designed as a prospective randomized trial but was closed
early because of a high incidence of early occlusion. Therefore, the data were analyzed …

Background and study aims: Recent progress in chemotherapy has prolonged the survival
of patients with malignant biliary strictures, leading to increased rates of stent occlusion …

Paclitaxel-eluting covered metal stents (PECMSs) and metallic stents covered with a
paclitaxel-incorporated membrane (MSCPMs) have been developed to increase stent …

Methods DCMSs were endoscopically introduced into 59 patients with unresectable
malignant extrahepatic biliary obstruction at four tertiary referral centers, and the patient …

Background Self-expandable metal stents (SEMSs) are used to relieve malignant biliary
obstruction. Objective To compare outcomes between covered self-expandable metal stents …

Background Although self-expandable metallic stent (SEMS) has a longer patency than
plastic stent (PS) for malignant biliary obstruction, stent occlusion can occur and drainage …

Background/Aim: Metallic stents have been used for the sole purpose of biliary drainage for
patients with malignant biliary obstruction. Since paclitaxel has antitumor effect, metallic …
