Abstract

Endoscopic retrograde biliary drainge is a useful method of palliative treatment of malignant biliary obstruction with respect to safety, rapidity in decompression of obstruction. However, despite of efforts to prolong patency of the stents, the main long term complication of current-widely used plastic endoprosthesis is to tendency for the stents to become clogged by sludge leading to recurrent jaundice and cholangitis, finally, obstruction of stents. Recently, in an effort to improve the patency of stent, variety of self-expandable metallic endoprosthesis have developed and which can be compressed into and inserted through small lumen catheter with large-bored lumen in expandable state. However, most of these open mesh of self-expandable stents allows tumor in growth which causes reobstruction, and additionally it is nearly impossible to retrieve the inserted prosthesis. Recently developed coil metal stent(Endocoil, Intent Co.), which, unlikely other previous metallic stent, has possibility of retrieving prosthesis and prevention of tumor ingrowth. We experienced a case of 52-year old male sufferd from malignant biliary obstruction due to recurrence of cancer at peripancreatic lymph nodes and combined with common bile duct stones on both proximal and distal side of the stricture, in whom Endocoil was implanted with sucessful decompression of obstruction and simultaneous removal of biliary stones located at both side of stricture.
