Newly Developed Fully Covered Metal Stent for Unresectable Malignant Biliary Stricture

Abstract EN

We herein report two patients with unresectable malignant biliary stricture who underwent stenting with a newly developed fully-covered metal stent.

In the first case of lower-middle bile duct cancer, a stent was placed through the stenosis.

In the second case of middle bile duct stricture due to lymph node metastases from gallbladder cancer, a stent was placed in the bile duct across the stenosis.

No procedure-related complications were observed.

Unevenness of the outer surface and a low shortening ratio are expected to lessen the occurrence of complications characteristic of covered metal stents such as stent migration and bile duct kinking.
