EXPANDABLE-METALLIC COIL STENTS FOR TWO PATIENTS WITH DISTALI BILIARY STRIOTURES

Abstract

We applied self-expandable metallic stents(EndoCoil)in two patients with unresectable pancreatic carcinoma causing obstructive jaundice due to involvement of the lower bile duct. Clinical improvement was had been achieved in both patients with no stmt dysfunction until death(9 and 11 months). This type of metallic stent has several advantages, i. e., its wide caliber(24F)after deployment, prevention of tumor ingrowth by the coilstructure, and removability. This new stmt is considered to be effective for lower bile duct stenosis.
