Abstract

Endoscopic biliary stenting has been performed since 1979. The stent is two different materials of plastic (PS) and metallic (MS). The metallic stent has Uncovered or Covered The benign biliary stenosis is placed PS. The stent patency of Covered MS is longer than Uncovered MS and PS in the distal malignant biliary stenosis. Uncovered MS is longer than PS in the hilar malignant stenosis . We don't become clear that the bilateral hepatic duct drainage is better than unilateral drainage in the patient with malignant hilar biliary stenosis In the future, we will available to use a drug-eluting stent and inbiliary radiation therapy I strongly expect the new stent ; easy to insertion, long stent patency (over six months), easy to exchange and reasonable price.
