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
longterm complication of current-wdely 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 ingrowth 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 suffered 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.
