P-249 Long-term oncologic safety of self-expandable metal stent as a bridge to surgery for obstructing colon cancer

Abstract

About 10-25% patients of with colorectal cancer suffer from acute colonic obstruction. Recently, placement of a self-expanding metal stent (SEMS) was widely used and it seems to be a safe and effective “bridge to surgery”, offering good palliation. But there is concern about long-term survival after the use of SEMS. Theoretically, tumor cell seeding can occur due to mechanical force during the stent insertion. To identify this theoretical validity, we surveyed long-term survival of malignant colonic obstruction using SEMS placement.
