摘要：
The present invention relates to a multi-hole stent for digestive organs, which comprises: a body having a hollow cylindrical shape and having a plurality of cells formed by intersections between wires； and a film installed to contact the inner surface of the body, wherein the film has at least one discharging hole formed therein. Accordingly, the multi-hole stent for digestive organs is installed on a stenotic region in the biliary tract to restore a diameter that has narrowed, thereby securing a bile discharge pathway. At the same time, the film installed on the inner surface of the body can prevent entry into the stent and re-stenosis due to the growth of a lesion such as a malignant tumor on the stenotic region, and can also provide a discharge pathway for bodily fluid produced from side branches around the biliary tract through the plurality of discharging holes formed in the film.
