Efficacy of a novel large-cell Niti-S stent with a slim delivery system for hilar biliary obstruction: a preliminary study.

Objectives: The large-cell Niti-S stent is useful for multiple stenting in patients with malignant hilar biliary obstruction (MHBO). Recently, a novel uncovered self-expandable metallic stent (USEMS) (a Niti-S large-cell SR slim delivery system) was developed. In this study, we aimed to evaluate the efficacy of this USEMS slim delivery system in MHBO patients.

[Outcomes of Bridge to Surgery for Obstructive Colorectal Cancer after Metallic Stent Placement in Our Hospital].

Recently, the endoscopic placement of self-expanding metallicstents (SEMSs)has become widespread for the treatment of acute malignant colorectal obstruction. This study was designed to evaluate the clinical outcomes of 22 patients with obstructive colorectal cancer who underwent SEMS placement as a bridge to surgery(BTS)from January 2012 to December 2015. The subjects comprised 15 men and 7 women with a mean age of 68.
