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.
自膨式金属支架（SEMSs）用于治疗恶性结直肠梗阻。本文报道了一名因晚期胃癌导致横结肠脾曲腔外狭窄而接受结肠裸支架置入术的患者。该患者在支架置入494天后出现结肠SEMS骨折。尽管此前已报道了支架置入的各种并发症，但结肠SEMS骨折的详细情况尚未见报道。由于接受姑息性SEMS置入术患者的预后改善导致支架长期放置，因此可能会出现各种并发症，预计未来像支架骨折这样的新情况会增加。
