[A Case of Rectal Cancer with Hemorrhagic Shock with Bleeding Controlled via Stent Placement That Underwent Radical Resection after Preoperative CRT].

Colorectal stents are used mainly for the palliative treatment of colorectal obstruction or preoperative re-obstruction. However, the hemostatic effect of covered stents reportedly induced bleeding of esophageal cancer and varicosities. Here, we report a case of mildly obstructed rectal cancer with severe anemia and hemorrhagic shock that resulted in pulsatile tumor bleeding.
