Abstract
An 86-year-old woman who was referred to our hospital because of anemia and abdominal distention was diagnosed with colon cancer, A circ cType2, cT4aN3M0, cStage IIIb by close exploration. Although we recommended radical operation, she did not hope to receive surgery. Accordingly we placed a colonic stent (22×60 mm, WallflexTM Colonic Stent). A plain abdominal x-ray study performed 12 months after the placement revealed migration of the stent to the left lower quadrant of abdomen. We decided to replace the stent and performed colonoscopy that demonstrated the displaced stent at the SD junction. The mucous membrane at the proximal verge of the stent showed marked edema with stenosis due to inflammation, through which the endoscope could not pass. Considering risks of causing intestinal obstruction and perforation at the site of the stent insertion, we created colostomy with double orifices.
