Metallic stents in biliary disease.

摘要: Abstract The development of self-expanding metallic endoprostheses which can be implanted easily, with minimal trauma, has revolutionized the non-surgical treatment both benign and malignant biliary strictures. Wallstent (Medinvent SA, Lausanne, Switzerland), a pliable, tubular stainless steel mesh, is stent choice for strictures in single session resulting shortened hospital stay patients undergoing palliation irresectable tumours. Although follow-up currently rather limited, it appears that occlusion rate Wallstents will lower than plastic no cases migration have been reported. Gianturco zigzag (Cook Inc., Bloomington, Ind, USA) should not used because rapid due to tumour ingrowth through struts. However, exerts strong, continuous, outward radial force ideally suited use small, but difficult manage, group recur despite surgery repeated balloon dilations.
