Fracture of a colonic self-expandable metallic stent in malignant colonic obstruction

Abstract

Self-expandable metallic stents (SEMSs) are used for the management of malignant colorectal obstruction. A patient who underwent colonic uncovered SEMS insertion for extraluminal stenosis in the splenic flexure of the transverse colon due to advanced gastric cancer is herein reported. The patient presented with a fracture of the colonic SEMS 494 days after SEMS insertion. Although various complications of stenting have previously been reported, the details of fractures of colonic SEMSs have not yet been reported. Because the improvement in the prognosis for patients who undergo palliative SEMS insertion leads to long-term SEMS placement, diverse complications can thus be expected, and new events like stent fracture are expected to increase in the future.
