摘要：

Technical difficulties in the deployment of a Wallstent biliary endoprosthesis may be encountered in situations where increased friction forces interfere with the smooth withdrawal of its covering membrane. Examples of such situations are stenting of left-sided and very tight strictures and deployment of two or more stents lying parallel to or overlapping each other. We describe a new technique using an 8F peel-away introducer sheath, which reduces the resistance caused by friction during the release of an endoprosthesis. The technique has the additional advantage of allowing easy advancing or removal of a partially deployed stent. This technique was successfully and safely used in 35 complex stenting procedures, which were carried out in 25 patients with mostly hilar strictures. Only two significant complications occurred (one haemobilia and one septicaemia), unrelated to the use of the sheath.
