Abstract

Background and Aim:

The aim of this study was to evaluate the efficacy and safety of one-step percutaneous transhepatic insertion of the Express LD stent, a balloon-expanding stainless steel stent used for the management of distal artery stenosis in the treatment of obstructive jaundice caused by various inoperable malignancies.

Methods:

Seventy-one consecutive patients with unresectable malignant biliary obstruction who underwent Express LD stent placement between 2007 and 2010 at our institute were reviewed.

Results:

Mean stent patency was 165 ± 144 days and mean patient survival was 180 ± 156 days, while the cumulative stent patency rate and patient survival rate at 6 and 12 months were 79% and 65%, and 38% and 16%, respectively. Stents were successfully placed in all cases without any stent migration or misplacement. Stent failure occurred in 14 patients (20%), and 16 complications were observed, including 12 cholangitis (17%), two cholecysitis (3%), and two pancreatitis (3%). Y-configuration stenting for hilar bile duct obstruction was the only independent prognostic factor for stent failure.

Conclusions:

One-step percutaneous transhepatic insertion of the Express LD stent is effective and safe for the management of obstructive jaundice caused by inoperable malignancies.
