【Abstract】 Biliary endoprosthesis, including plastic stents and metallic stents, have been widely used in the management of various benign or malignant bile duct stenosis. Although the short-term effect is most satisfactory, the long-term result is unsatisfactory because of the displacement and restenosis of the stent. Metallic stent is superior to plastic stent in keeping the stent open for long time and the technique has been improved gradually. This paper aims to make a review of the related literatures and to summarize the recent progress in the applied research.更多还原
