Abstract
A 70-year-old woman was introduced to our hospital with severe vomiting Endoscopic examination showed duodenal carcinoma of the third portion. Simultaneously, the findings of abdominal computed tomography showed multiple metastatic liver tumor with much ascites after treatment for dehydration. The duodenal tumor was not thought to be curatively resectable. To relieve duodenal stenosis, an expandable metallic stent (EMS) was successfully and easily placed with longover tube of Ileus Aid System. The long over tube equipped with a balloon at the tip of the tube facilitated stent placement for sever duodenal stenosis and assisted the insertion by transporting the strength of pushing the tip of EMS because the balloon was fixed at the first portion of duodenum.
