The first transendoscopic plastic to self-expandable metal stent replacement in Serbia and Montenegro using a diagnostic duodenoscope.

Abstract

Studies have shown that SEMS remain patient longer with fewer associated complications compared with conventional plastic strents. Zilver stent, a nitinol zig-zag mash SEMS has a special advantage, having a thin introducer diameter of 7 Fr with a fully deployed span of 10mm. For a 48-year-old woman presented with obstructive jaundice and a diagnosis of unresectable pancreatic carcinoma with consequent stenosis of common bile duct (CBD), infiltration of local blood vessels and life expectancy longer than six months, it was decided that an endoscopic palliative drainage procedure should be performed. The technique of transendoscopic plastic to metal stent exchange is described, using a diagnostic duodenoscope. The patient lived 7 months after implementation of Zilver stent and died anicteric due to progression of a primary disease. The transendoscopic plastic to metal stent exchange is feasible palliative method which requires a basic endoscopic equipment and experienced staff and therefore is applicable in developing countries as well.
