The surgical management of malignant colorectal obstruction is still controversial and has higher associated mortality and complication rates compared with elective surgery. Placement of self-expanding metallic stents (SEMS) has been proposed as an alternative therapeutic approach for colonic decompression of patients with acute malignant obstruction. SEMS placement may be used both as a bridge to surgery in patients who are good candidates for curative resection and for palliation of those patients presenting with advanced stage disease or with severe comorbid medical illnesses.
恶性结直肠癌梗阻的手术治疗仍存在争议，与择期手术相比，其相关死亡率和并发症发生率更高。自膨式金属支架（SEMS）置入已被提议作为急性恶性梗阻患者结肠减压的一种替代治疗方法。SEMS置入既可以作为适合根治性切除患者的手术桥梁，也可用于缓解晚期疾病或患有严重合并症的患者。
