Large bowel obstruction can be caused by advanced colonic cancer, extracolonic obstruction or benign strictures. The technical success rate of colonic stents for the treatment of colorectal obstruction is about 87% with complications or technical failure at about 14%. Mortality associated with the procedure is <4% and perforation is 4.5%. This article will discuss who would benefit from colonic stents including bridge to surgery, palliation, benign strictures and who should be performing this procedure. The insertion of stents in the colon has been primarily studied in the left colon, although proximal obstruction will also be discussed. The timing of stent insertion, in relation to symptoms and chemotherapy, will be discussed.

结肠支架：谁、在哪里、何时


大肠梗阻可由晚期结肠癌、结肠外梗阻或良性狭窄引起。结肠支架治疗结直肠梗阻的技术成功率约为 87%，并发症或技术失败率约为 14%。与手术相关的死亡率为 <4%，穿孔为 4.5%。本文将讨论谁将从结肠支架中受益，包括手术桥接、姑息、良性狭窄以及谁应该进行此手术。支架插入结肠主要在左结肠中进行研究，但也将讨论近端梗阻。将讨论支架置入的时间，与症状和化疗有关。
