Abstract:

Endoscopic stent placement using Fully Covered Self-Expandable Metal Stent (FCSEMS) is gold standard method of treating for malignant biliary obstruction. However, if cystic duct is not occluded by malignant tumor, when FCSEMS was placed across cystic duct, acute cholecystitis may occur. In this condition, uncovered self-expandable metal stent (UCSEMS) or plastic stent may be selected as alternative drainage stent, however, stent patency is shorter than FCMS placement. Recently, novel UCSEMS is available (Double bare metal stent). This stent may have clinical impact for long stent patency compared with UCSEMS because preventing tumor in growth may be obtained, and prevent cholecystitis compared with FCSEMS because cystic duct is not occluded. Herein, we reported successful treatment for acute cholecystitis after FCSEMS placement using this double layer metal stent. Double bare metal stent may be effective to prevent acute cholecystitis after stent placement
